4. Geketta TiGRLN'A (Schreb.). 



Sixteen flat skins of a G-enet which may probably be referred 

 to this species. They vary much in the amount of spotting on 

 the back, some being thickly spotted with rusty red here, whilst 

 others are quite without these markings. But there are inter- 

 mediate specimens. 



5. VivEEEA ciVETTA, Schreb. 



Three flat skins of this \^'idely-8pread species. 



6. Herpestes galeea (Erxl.) ; Thomas, P. Z. S. 1882, p. 72. 

 One flat skin. 



7. COBUS CEAWSHAYI, Sp. nOA'. 



Similis C. ellipsiprymno, sed colore, prcecipiM in dorso, saturatiore, 

 et disco anali alho : fascia uropygiali alba nulla, et statura 

 2)aido minore diversus. 



Mr. Sharpe sends a single flat skin of the Mweru Waterbuck, 

 and Mr. Crawshay's collection contains 2 heads and 3 flat skins of 

 the same animal. I think there can be no question of its being 

 distinct from C. ellij)sij)r)j)nnus, and I propose to attach to it the 

 name of Mr. Crawshay, who has done such good work on the 

 Antelopes of Xyasaland \ 



The fur of Crawshay's Waterbuck, as will be seen from the 

 skin which I now exhibit, generally resembles that of C. elliiisi- 

 2>ri/mnus, the animal being covered ^ith the same harsh, lengthened, 

 thinly spread hairs. But the colour is considerably darker, being of 

 a dark iron-grey on the dorsal surface, which passes into blackish 

 on the back of the neck, upper portion of the limbs, and tad. 

 This colour gets gradually lighter and more gi'eyish on the flanks, 

 and passes on each side into whitish on the belly. There is no 

 sign of the distinct rump-band v/hich is so clearly marked on 

 0. ellipsijjrymnihs, where it is bordered on each side by dark grey ; 

 but in the present species the A^hole anal disk is white, separated 

 on the dorsal line by the dark medial streak which passes into the 

 short black bushy tail. The whole length of the flat skin in the 

 present example is about 56 inches, the length of the tail about 

 15 inches. 



The horns of Crawshay's Waterbuck, of which I exhibit a fine 

 pair obtained by Mr. Crawshay near Ehodesia, the British Central 

 African Station on Lake Mweru, can hardly be distinguished from 

 those of C. ellijjsi'prijinnus. The present pair measure about 24 

 inches in length along the curve. They are strongly ringed to 

 near their extremities. The points are about ll'o inches apart. 



Assuming the validity of the species just described, I am ac- 

 quainted with four species of the peculiar group of the genus 

 Cohus, commonly called Waterbucks, and distinguished by their 

 rough and elongated hairs, which are longer and divergent on the 

 neck, the tufted tail, and the large, heavy, strongly -ringed horns,
