1901.] ON THE KASHMIR IBEX. 91 



braslUensis is more pointed than that of the Bornean Dolphin, and 

 lacks the anterior ridge-like extension of the latter. Moreover, the 

 head is less elevated above the beak than is the case in the present 

 form, althongh it is true that this may be due to immaturity. In 

 the skull of the Brazilian species the beak appears to be much wider 

 than in the specimen under consideration, while the teeth seem 

 relatively larger. S. guianensis, which is said to have ^ teeth, may 

 be identical with one of the foregoing ; and, in any case, is too im- 

 perfectly known to admit of exact comparison, in the absence of 

 the type specimens. 



I have not been able to identify the Brazilian specimen wdth any 

 of the South- American Dolphins recently described by Dr. E. A. 

 Philippi \ and am indeed doubtful whether any of them belong to 

 Sotalia . 



Under these circumstances I see no other course but to make 

 the Bornean Dolphin, at least provisionally, the type of a species, 

 for which the name S. borneensis will be appropriate. The specific 

 characters will be apparent from the description above given. 



The specimen was captured on September 12th, 1900. 



2. Note on the Kashmir Ibex (Capj'a sibirica sacin). 

 By R. Lydekker. 



[Received January 22, 1901.] 



(Plate IX.) 



(Text-figure 12.) 



So far as I am aware, no coloured figure of the Ibex inhabiting 

 the mountains which border the northern and eastern sides of 

 the Valley of Kashmir has ever been published, and I accordingly 

 desire to direct attention to a skin which, through the intervention 

 of Rowland Ward, Ltd., will shortly be acquired by the British 

 Museum. The animal (a male) to which this skin belonged was 

 shot by Captain E. F. Holden below the Zogi-la, the pass on the 

 Leh route dividing the Siud Valley of Kashmir from the Tibetan 

 district of Dras. Captain Holden has had the head mounted for 

 his own collection, and the remainder of the skin he has kindly 

 offered to present to the Museum. 



This animal was in the winter coat at the time of its death ; 

 and is, I take it, the Capra sakeen of Blyth, which is generally 

 described as of a dii'ty white colour in winter, with dark uuder- 

 parts and legs, and browner in summer. Few naturalists, I think, 

 have, however, any idea that it is really as white as is shown to be 

 the case by the present example, which may be briefly described 

 as follows : — 



AVhole of back and the basal portion of the neck creamy 

 huffish white, with a very faint and incomplete light brown dorsal 

 streak, becoming broader and darker towards the tail, which is
