bull for example Mr. Lydekker judges that the horns would not 

 have measured when unworn more than 15 or 16 inches along the 

 curvature, whereas in the male of the typical form the length is from 

 abont 20 to 25 niches. As the skulls figured by Mr. Lydekker show, this 

 difference in length depends upon the greater shortness of the basal 

 horizontal position of the horn in the Bhotan as compared with the 

 Assamese Takin rather than in the iireater shortness of the recurved 

 terminal portion. For instance in the skull of the Assamese Takin 

 figured the extreme length of the basal horizontal portion is just 

 about equal to the greatest inter-orbital width of the skull, whereas 

 in the figured skull of the Bhotan specimen, the basal horizontal 

 portion of the horn is markedly less than the inter-orbital width of 

 the skull, this inter-orbital width being approximately the same in the 

 two skulls. Skulls of young males and females of the Bhotan Takin 

 are correspondingly smaller. 



Unfortunately detailed comparison between the skulls of the two 

 races was not possible. The two agree, however, in general colora- 

 tion, in the darkness of the head and the extension of the spinal 

 stripe from the occiput to the tail. In a young female presented 

 to the Zoological Society by Mr. J. Claude White and now living in 

 the Gardens in Regents Park, the coloration is practically the same 

 as that of the adult bull of the Assamese species mounted in the 

 British Museum — the specimen from which Mr. Lydekker's concep- 

 tion of the coloration of the typical form of B. taxicolor was derived — 

 except that there is quite a considerable amount of yellowish brown 

 hairs on the forehead and cheeks, so that there is no sharp line of 

 demarcation between the colours of the head and the neck, such as is 

 seen in the stuffed example in the British Museum. Whether this 

 difference holds good in all cases it is impossible to say without further 

 material wherewith to check it ; but considering the great variation 

 in colour exhibited by the typical Assamese Takm, it would be rash 

 to assume constancy in all cases for the coloration of the head noticed 

 up to the present time only in one young female specimen.
