[10] Unless when “_Antilope quadriscopa_” is rediscovered it shall prove to belong to this subfamily. See below, p. 124. [11] An animal to which the following names refer has been described as a member of this genus:-- _Antilope (Cephalophus) quadriscopa_, =H. Sm.= Griff. An. K. iv. p. 261, fig. (♂), v. p. 345(1827). _Quadriscopa smithii_, =Fitz.= SB. Wien, lix. pt. 1, p. 167 (1869). _Hab._ Senegal. The figure, however, shows a species more like a Gazelle than a Duiker, although some of its characters seem rather Cephalophine. Whatever it may have been it has never been rediscovered, nor is its description sufficient for us to assign it to its proper place in the group. [12] 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. [13] Hand-l. Rum. B. M. p. 94 (1873). [14] This name has no connection with the “Antilope zébré, _Antilope fasciata_, Geoff.,” mentioned (without a description) by Desmarest (N. Dict. d’H. N. (1) xxiv. tabl. p. 33, 1804). There is no evidence available to enable us to determine what this name refers to. Transcriber’s Notes: 1.
