Note 12 — Subfamily II. CEPHALOPHINÆ.

From Loanda, farther south, the Lisbon Museum received, in 1869, the head of a large Duiker, which our friend Dr. Barboza du Bocage referred, rightly as it now proves, to Gray’s C. longiceps. Afterwards, however, in 1878, struck by the great development of the rufous crest, of which no mention had been previously made, he distinguished it as C. ruficrista. Thanks to his kindness we have now had an opportunity of comparing the typical head with those of the mounted specimens in the British Museum, and find it to be unquestionably the same, although, as the latter are very old, the rufous crests have been worn off and but little trace of them is left. Our figure (Plate XIV. fig. 2) shows, however, that in rather younger animals the crest is both well developed and very much of the same rufous colour as in the Lisbon example.
