802 MR. R. LYDEKKER ON AN [ISToV. 3,. 



from Mr. Brooke, in whicli it is stated that old males of the 

 Sze-chuen Takin grow to a very large size, as, indeed, is indicated 

 by the skin and skull sent to the Museum. Also, that in summer 

 the long and rough orange or reddish coat is replaced by one of 

 short greyish hair.]

Subadult male (1) and female (2) of the Sze-chueu Takin {Budorcas tibetanns),

4. On an Indian Dolphin and Porpoise. 

 By R. Lydekker. 



[Received September 2, 1908.1 

 (Plates XLIV. & XLV.^=) 



Once more I am indebted to the Director — Lieut. -Colonel F. W. 

 Dawson — of the Trevandrum Museum for sketches and measure- 

 ments of certain Cetaceans recently captured on the Travancore 

 coast. These are represented by three specimens, referable to two 

 species ; they differ to a greater or less degi-ee from the typical 

 forms of all the Dolphins and Porpoises hitherto described fi'om 

 Indian waters, and from the world generally. The most i-emark- 

 able fact about the new specimens is that two of them are Bottle- 

 nosed Dolphins, referable to Tursiojys, of which genus, in addition 

 to the typical T. tursio, I have already recognised (Proc. Zool. Soc. 

 1905, vol. i. pp. 125-128) three, if not indeed four, Indian 

 species. 



Col. Dawson informs me that the^ two examples of this 

 apparently new Bottle-nose Avere caught by fishermen about six 

 miles to the north of Trevandrum, in the spring of the present, 

 year (1908). The skeletons of both were preserved ; and one of 

 these has, at my request, been presented by Col. Dawson to the 

 British Museum, as it seemed desii-able that an appai'ently new 

 form should be represented in the chief English collection. 



The following particulars concerning these two specimens. 

 {A and B) have been supplied to me from Ti-evandi'um : — 



Length from tip of snout to cleft in flukes ... 

 Do. to origin of dorsal fin 



„ flipper 



,, genital groove 



,, anal groove 



Length of dorsal fin 



„ flukes 



Expanse of flukes
