Suborder II. BALÆNOPTEROIDEA (cf. p. 36).

Balænopteridæ, Gray, l. c. pp. 61, 106.

Balænopteroidea, Gray, Synops. Whales & Dolph. p 2.

Head moderate. Body elongate. Dorsal fin distinct, rarely wanting. Belly longitudinally plaited, rarely smooth. Baleen short, broad. Maxillary bones broad. Pectoral fin lanceolate; arms elongate; radius and ulna much longer than the humerus. Fingers 4, subequal. Vertebræ of the neck free, or partially united. Tympanic bones oblong or ovate.

Family 2. AGAPHELIDÆ. Scrag Whales.

Head moderate; body elongate; hinder part of the back keeled and notched. Cervical vertebræ free. Pectoral fin lanceolate. Fingers 4. Throat without plaits. No dorsal fin. Ribs single-headed.

Mr. Cope “mentioned that he had an opportunity of examining a portion of a specimen of the Scrag Whale of Dudley, Balæna gibbosa of Erxleben, and ascertained that it represented a genus not previously known. It was a Fin-back Whale; but without dorsal fin or throat-folds, resembling superficially the genus Balæna. The baleen short and curved. The genus was called Agaphelus.”

1. AGAPHELUS.

Cervical vertebræ free. Fingers 4. Throat without plaits. No dorsal fin. Ribs single-headed. Scapula with acromion (Cope, Proc. Soc. N. Sc. Phil. 1869, p. 16).

Agaphelus, Cope, Proc. Soc. N. Sc. Phil. 1868, pp. 159, 225; Gray, Ann. & Mag. N. H. 1870, vi. p. 200.

“Fingers four, elongate. Cervical vertebræ ⸺? Lumbar and anterior caudal vertebræ longer than their greatest diameter. Dorsal fin wanting. Gular and pectoral region without folds. Scapula with well-developed acromion and coracoid. Baleen narrow, short, curved.

“The baleen is peculiar; throughout the length of the maxillary bone it nowhere exceeded one foot in length, and the width of the band, or length of the base of each plate, four inches. It is of a creamy white; the fringe very coarse, white, and resembling hogs’ bristles.

“The ear-bone is much compressed, with an inferior carina, towards which the lip of dense bone is suddenly decurved. The longitudinal opening is much contracted, especially anteriorly, where the bone is pinched up into a keel; and there is no abrupt concavity of the inner lip at that point. External surface not very rugose. Total length 3 in. 2·5 lines.

“The scapula preserved is low and elongate, with well-developed acromion and coracoid process. It is evidently of the type of Balænoptera and Physalus; the ulna and radius relatively less elongate than in Sibbaldius laticeps and borealis, being 1·5 as long as the humerus, thus resembling Physalus.

“The four fingers, with the second much the longest, form a fin of the type of those genera.

“The ear-bone is much more compressed than in Physalus antiquorum or Sibbaldius laticeps.

“The mandibular ramus is rather massive, moderately curved, and with a more elevated coronoid process than in any Whale that I have seen.

“The greatest peculiarity is in the form of the lumbar and anterior caudal vertebræ; they are of a much more elongate form than any I have seen or found figured, excepting those of the Balænoptera rostrata (as figured by Gaimard in ‘Voyage de la Recherche’), which, however, are relatively shorter. Those of the present species are of greater length than transverse diameter, the lumbars most elongate; all furnished with an acute hypapophysial keel and concave sides, and entirely transverse diapophyses. This peculiarity is consistent with the account of my informant, who stated the animal to have been of an unusually elongate and slender form. When it came ashore it had perhaps been dead ten days; the flukes and muscular region as far as the third caudal vertebra had been devoured, probably by Sharks and Killers, and the abdominal region much lacerated; the edge of a fin preserved was slit by the teeth of some carnivorous enemy. The measurement from the end of the muzzle to the end of the third caudal was 35 feet, which may be reduced to 33 feet axial. Up to this point the dorsal line was, according to my informant, entirely smooth, without knob or fin, or scar of one; hence I suppose the fin (if present) to have been situated, as in Sibbaldius &c., at the posterior fourth of the length, and not, as in Balænoptera, on the posterior third. It may then be safely assumed, bearing in mind the form of vertebræ, that ten feet of the whale’s length had been removed, making in all 43 feet. That the species attains over 50 feet is probable, as the present individual was quite young, the epiphyses separating from the vertebræ with the greatest ease. The slender form of the animal is corroborated by the slenderness and slight curvature of the ribs, one attached beneath the scapula, probably the second, being narrower than the corresponding ones in Sibbaldius. I therefore think it most probable that in this form the anterior ribs are single-headed.”—Cope, l. c. p. 223.

“The points in which this species differs from those of the genus Balæna previously known are numerous, and will no doubt be increased on a further knowledge of the animal.

“The head, between one-fourth and one-fifth of the total length, allies it to the shorter-headed species. From the B. australis the number of dorsal vertebræ, and the colour and shortness of the baleen, distinguish it; and no doubt other features will be brought out when we are acquainted with the Cape species. The dorsal serration is not known to occur in any species of the genus Balæna, though said to be characteristic of the A. gibbosus, whose characters I have just given.

“Two Balænæ have been described as inhabiting the North Pacific Ocean, Balæna Sieboldii, Gray (Catal. Cet. 1865, p. 96), and Balæna cullamach, Chamisso (Nov. Act. Acad. Cæs. xii. p. 251, tab.)

“Both have been established on figures carved by the natives, of the Japanese and Aleutian Islands respectively, the former under the supervision of a naturalist, the traveller Siebold. The carving of the B. cullamach, judging from the figure given by Chamisso, can but doubtfully represent any species; but if the species exist, it will rest on the following diagnosis of its describer:—‘Rictu amplo forma litteræ S curvato, elasmiis maximis atro-cæruleis, spiraculis flexuosis, in medio capite, tuberculo in apice rostri (ex imagine), pectore pinnisque pectoralibus albis, dorso gibboso sexpinnato.’

“These are, however, true Balænæ. A species of Agaphelus exists in the Kamtschatkan seas, according to Pallas, who, however, derives his information solely from wooden models made by the Aleutian Islanders. This is not sufficient basis for an introduction to the scientific system; yet Pallas indulges in applying to it the name Balæna agamachschik. The pectoral limb of this species is said, however, to be white, with the underside of the flukes, characters not found in the A. glaucus. Dr. Gray has already (Cat. Brit. Mus.) indicated that this, if reliable, indicates a genus unknown to him.

“The Agaphelus glaucus is the Grey Whale of the coasts of California. Two specimens have been examined by my friend Wm. H. Dall, of the scientific staff of the U. S. Russian-American Telegraph Expedition, one of them near Monterey; and descriptions, as complete as the state of the specimens would allow, were made.

“These, which were sent to the Smithsonian Institution, and placed in my hands by Prof. Baird, are quite sufficient to indicate a Whale of a species hitherto unnoticed, and to render certain its future identification.

“Dorsal vertebræ and ribs 13; lumbar and caudal (those in the fluke cut off with it) 28. Scapula, breadth and height not very different, with a short broad coracoid process; its head opposite first rib. Apparently only four fingers, of which the second is the longest. 145 laminæ of baleen on each side, the longest 18 inches long; colour bright yellow.”—Cope, Proc. Ac. N. Sc. Philad. 1868, p. 226.

“A second and more full examination of the Megaptera osphyia, Cope, furnishes the following additional points and characters. The specimen is young, and measures in its present condition 34 feet. It has, however, lost a considerable number of caudal vertebræ, and, from the posterior part of the column, of intervertebral cartilages also; add to this the shrinking of the cartilages preserved, and the increase of length would perhaps amount to 8 feet, giving 42 in all. The asserted length of 50 feet, line measurement, which I quoted in my original description, is no doubt an exaggeration.

“The glenoid process is margined by an angular prominence, the rudiment of the coracoid, precisely as in the M. brasiliensis. The diapophysis of the atlas is a flat vertical plate, extending from opposite the base of the foramen dentatum to opposite the widest point of the spinal canal; inferior posterior outline of the atlas broad, slightly concave mesially. The mandible is peculiar in the strong angular process, which extends from behind, round the side, projecting as far as the condyle, and separated from it by a deep groove. The third and fourth cervicals are united by the neural arch. The first rib is very broad at the extremity; length 37 inches, width at end 8·22 inches. The orbital processes of the frontal bone are not contracted at the extremities as in M. longimana, but are more as in Balænopteræ; entire width over and within edge of orbit 15½ in.; length to vertical plate of maxillary 31 inches. The baleen measures 2 feet in length, is black, with three rows of coarse bristles. Its base is one curve; its length is spirally twisted. The species is probably one of the largest of the Balænidæ.”—Cope, Proc. Acad. Nat. Sci. Philad. 1868, p. 194.

“The first Whales appear in the Abrolhos waters at about the end of May, and they stay until October. The females often bring young calves with them, and appear to seek the shelter of the reefs. The headquarters of the Abrolhos fishery is at Caravellas, or, rather, at the mouth of the river Caravellas, where are situated the armações or trying-houses.”—E. Hartt, Geology and Physical Geography of Brazil, p. 182.

“The fishery begins at Bahia, according to Castelnau (Expédition dans l’Amérique du Sud, tome i. p. 750), about the 13th of June, and lasts till the 21st September. At Caravellas I was assured that the Whales always appeared later than at Bahia, and the fishery does not always begin until the last week in June, continuing through the month of September.”—E.
