L., but as the fourteen examples which I have examined all 

 retain their distinctive characters, it seems advisable to regard 

 it as a distinct species, at least provisionally. I retain for it 

 Buquet's collection name under which it already stands in all 

 the older collections. The chief points in which it differs from 

 Linne's species are: — (1) the absence of the deep central 

 furrow on the rostrum ; (2) the lower lateral sulcus is dis- 

 tinctly longer than the upper and parallel with it, whereas in 

 verrucosus it is shorter and the sulci converge apically ; 

 (3) the thoracic tubercles are more elevated ; (4) the discal 

 punctures on the elytra are deep and simple, whereas in 

 verrucosus they are shallow and with a small but distinct 

 granule at the side of each ; (5) the discal portions of the 

 intervals 1 and 3 near the base are quite plane and smootii, 

 and not distinctly tuberculate or carinate.

LVIII. — The Specific Name of the Ohapi presented hy Sir 

 Harry Johnston to the British Museum. By E. Ray 

 Lankester, M.A., LL.D., F.R.S., Director of the Natural 

 History Department of the British Museum. 



Since it appears probable (according to Dr. Forsyth Major's 

 observations) that the skin of the Okapi received in Brussels 

 in May last belongs to a species of the genus Okapia distinct 

 from that represented by the entire skin and skull (the larger 

 of the two skulls) sent home by Sir Harry Johnston in the 

 previous year, and now mounted and exhibited in the public 

 gallery of the Museum, and since, moreover, according to 

 Dr. Forsyth Major's observations, the " bandoliers " of striped 

 skin sent home by Johnston at a still earlier date,' and named 

 Equus Johnstoni by Sclater, belong to the sjiecies received in 

 Brussels in May 1902, and not to the species represented by 

 the entire skin and skull sent by Johnston in 1901, it becomes 

 necessary to assign a new name to the latter. This is the skin 

 figured and described in my memoir in the Trans. Zool. Soc. 

 1902 (vol. xvi.): the larger of the two skulls and the lower 

 jaw there described and figured belong to it. I propose to 

 call this species after the Belgian officer Mr. Eriksson, who 

 obtained it at Sir iJarry Johnston's request, as recorded in 

 my memoir above cited. This species will therefore stand 

 as Okapia Erikssoni, Lankester. Tiie type is the stuffed
