4, Capricorxis collasinus Heiule. 



Heude's species collasinus is represented in the collection by a 

 fragment of a skull Avitli one very long horn {^\") attached, which 

 bears a resemblance to those from Chen-kou-ting. Hende had 

 the complete skull reconstructed in a drawing which he has 

 reproduced on pi. xlii. figs. 5-8 of tome iv. of his Memoires. The 

 geographical position of this Sei'ow would almost preclude its 

 being placed with the Chen-kou-ting specimens, and, as the horn 

 diffei'S mai'kedly from those of the specimens from Tonkin, it 

 would seem advisable to let the name remain till material for 

 better comparison is forthcoming. The description, if it may be 

 called such, appears on p. 211, tome iv. of Mem. etc. 



5. CapricorjS'IS rocherianus Heude. 



Finally, there remain the large series of skulls from Along Bay 

 (Bale de Halong) and Keso in Tonkin to be dealt with. With 

 the exception of the specimen labelled C. herthetianus from Keso, 

 all the skulls in this series are decidedly smaller than those 

 of the Ssuchuan series. They are also proportionately deeper, 

 including the herthetianus specimen. The horns of all the skulls 

 are smaller and shorter than any of the Ssuchuan or other 

 Chinese skulls. Added to these skull and horn differences is the 

 fact that the colour of the coat differs markedly from the other 

 species, it being black, inclined to blue-black, with a distinctly 

 brown face (more so than in the other species) and creamy-white 

 legs. Besides this, there is an entire absence of any white or 

 cream mane, so that the animal is certainly distinct from the 

 other Chinese forms. Nevertheless, there is nothing in the series 

 to justif}^ Heude's division of it into ten species. The name 

 rocherianus is the first which has a description, and as there seems 

 to be no real difterence between the others, it should be applied 

 to the whole series. The skull labelled thus is typical of the 

 others, and was collected as far back as 1887 by M. Rocher*. 

 The rest of the names for the Tonkin specimens should be 

 considered invalid. 



Thus, Heude's twenty-four species and David's one may be 

 reduced to the following five : — 



1. Capricornis argyrochcetes Heude. The Province of 



Chekiang, S.E. China, 



2. ,, vidianus Heude. The region of N.E. 



Ssuchuan and S. Shensi, Central China. 



3. ,, milne-echoardsi David. W. Ssuchuan, N.W. 



Ssuchuan and S.W. Kansu, W. China. 



4. ,, collasinus Heude. Kuang-tung Province, 



S. China. 



5. ,, rocherianus Heude. Tonkin, S.W. China.
