174 Mr. 0. Tliomas on 



Type. Adult male. Original number Gl. Collected 3rd 

 December, U)04. Presented by Capt. G. 13. Gosling. 



" Native name in Kanura ' Dagull.^ " 



"Iris hazel.'^— (7. B. G, 



A study ot" the very imperfect material of the C. patas 

 group available in the British Museum and the Zoolojjical 

 Gardens collection * gives evidence that there are in West 

 Africa two forms of the Patas monkey — one, represented 

 by examples from Sierra Leone, with the moustache region 

 black J and the other, from more to the east, with this part 

 white, and thus leading towards C. pyrrhonotas, which has 

 the nose also white. 



No mention of the colour of the lips was made in the 

 original description of the Patas, but specimens from Sene- 

 gambia were referred to that species by F. Cuvier and other 

 earlier authors, and that region may therefore be treated as 

 the typical one. The Sierra Leone specimen would thus 

 liave the best right of those available to be considered true 

 C. patas J and I give a new name to the more eastern form, 

 as represented by the fine example sent home by Capt. 

 Gosling. 



Scotophilus nigrita herero, subsp. n. 



Hairs of back about 5*5 mm. in length.

 " cream-buff.^' 



Dimensions of the type : — 



Forearm 59 mm. 



Greatest length of skull 20"1. Front of canine to back of 

 m^ 7-1. 



Hah. Northern Damaraland. Type from Elephant's Vley, 

 about 18° S., 17° 30' E. Other specimens from Otjoro. 



Type. Female. Original number 260. Collected 8tli 

 August, 1859, by Mr. C. J. Andersson, and received in the 

 Tomes Collection. Twenty specimens examined. 



This is the bat referred by Mr. Tomes f to Nycticcjus 

 2>lanirostiis, Peters, but it is far paler, both above and below, 

 than either that or any other described race of the widely 

 distributed S. nigrita. The variation in colour among t!ie 

 large series collected by Mr. Andersson is much less than 

 one would gather from Mr. Tomes's note. I can find no 

 specimens which are anything like " as dark in colour as the 



* For these latter I have to thauk Mr. Pocock, the Supeiiutendent.
