620 MR. W. T. BLANFORD ON THE [DcC. 6, 



The incisors of the lower jaw are thick and round. The skull, 

 in comparison with the skull of Capra caucasica, has neither such 

 a developed forehead nor such a hroad occipital region. 



The fur has the following peculiarities : the general colour is a 

 brownish grey, with more expressed yellowish tinge than in Capra 

 caucasica ; the head is darker, a light spot on the nape of the 

 neck is but a little dereloped ; along the ridge of the spine a dark 

 stripe. The anterior and posterior extremities are dark with a very 

 observable light stripe on their posterior side. The fur on the belly 

 is light brownish. The beard, brown in colour, is longer and narrower 

 than in Capra caucasica ; the tail, on the contrary, is shorter. 



It seems to me that all the figures of horns on the plate accompany- 

 ing Mr. Biichner's pamphlet (taf. 1) should be referred to Capra 

 severtzowi. 



The distribution of Severtzow's Goat is more extensire than 

 that of Capra caucasica ; this animal is met with throughout the 

 whole of the alpine region of the western Caucasus, and, according 

 to the observations of Mr. Dinnik, presents some marked distinctions 

 in the specimens inhabiting its westernmost parts. " Their horns 

 are comparatively short, thick, with a more decided outward turn 

 at the base, and with large nodules on the anterior side. Their 

 section taken near the base proved them to be quadrangular with 

 rounded corners, rather than triangular. The circumference at the 

 base of the horn as compared with the length measured along the 

 anterior surface is equal to half or a little more. The colour of the 

 fur of this Goat is also perceptibly lighter." 



It is possible that this western Caucasian Mountain-Goat may form 

 a third distinct species, or at least a variety of Capra severtzowi. 



Both the described typical specimens of Goats {Capra caucasica 

 and Capra severtzowi) are now preserved in the Zoological Museum 

 of the University of Moscow.

I. On the Simla silenus and S. veter of Linnceus, and on the 

 proper name of the Malabar Bearded Monkey. 



Ever since the time of Schreber the specific name silenus has 

 been applied to a bearded species of Macacus peculiar to the 

 Malabar coast. This Monkey is commonly known amongst 

 European zoologists as the Wanderoo, and in many European 

 works on natural history is said to inhabit Ceylon ; but it was long 

 since shown by various writers that the species is not Ceylonese, and 

 that the Wanderoo of Ceylon is a Semnopithecus. The question I 

 have endeavoured to solve is whether the bearded Macacus of 

 Malabar is the Simia silenus of Linneeus.
