Note 395 — Chapter XXI · PYCNOGONIDA[393]

Brünnich’s description (“Entomologia,” 1764), is still more accurate, and is worthy of transcription as an excellent example of early work. “Fig. iv. Novum genus, a R[ev.] D[on.] Ström inter phalangiis relatum, Söndm. Tom. i. p. 209, t. 1, f. 17. Exemplar hujus insecti, quod munificentia R. Autoris possideo, ita describo; Caput cum thorace unitum, tubo b excavato cylindrico, antice angustiore, postice in thoracem recepto, prominens; Oculi iv. dorsales, a, in gibbositate thoracis positi; c, Antennae 2 tubo breviores moniliformes, subtus in segmento thoracis, cui oculi insident, radicatae; segmenta corporis, excepto tubo, iv., cum tuberculo e medio singuli segmenti prominulo. Pedes viii., singuli ex articulis vii. brevissimis compositi, ungue valido terminati. Ex descriptione patet insectum hoc a generibus antea notis omnino differre, ideoque novum genus, quod e crebris articulationibus Pycnogonum dico, constituit.” The confusion between Cyamus and Pycnogonum seems to have arisen with Job Baster, 1765; cf. Stebbing, Knowledge, February 1902, and Challenger Reports, “Amphipods,” 1888, pp. 28, 30, etc.
