932 Mil. U, LYDUKKBtt ON A NEW [Dec. 1, 



Isubra Deer is larger. In the female it leaves the pudenda un- 

 covered. The caudal disk is very strongly marked, extending, as 

 in the AVapiti, largely over the base of the tail. In the male it is 

 foxy, but in tlie other speciniens bright straw-yellow. A dark 

 band, extending inl'eriorly on to the thigh, borders tlio disk. In 

 both sexes the head is elongated, and the nose somewhat convex. 

 A pair of antlers sent from East Siberia ' have two forwardly- 

 projecting brow-tines and a middle tine. While the beam goes in 

 a regular curve to end in a termiual tine, there is given ofi a strong 

 hind-tine, which is likewise single. Wherever tines are given off, 

 the antlers are flattened, and resemble those of 0. eustephanus, 

 as figured by Blanford '." 



It is added that the young are spotted, and it is suggested that 

 the species may prove identical with G. eustejilianus of the Thian- 

 Shan. 



Prom this description it appears that O. luelidorfi has a well- 

 marked caudal disk at all seasons, and this is certainly the case with 

 the nearly allied Wapiti, whereas in the Woburn deer the summer 

 coat in the second year is uniform. The colour of the summer 

 coat is also much redder than in the Wapiti, and, apparently, than 

 in C. luehdorfi. Then, again, the neck-fringe, in tlie present 

 condition of the animal, is quite different to both the others. 

 Moreover, the appearance of the deer is not quite that of a Wapiti, 

 although it seems to belong to the same group. Further com- 

 parisons cannot be made till the antlers of the third year are 

 developed ; and it is, therefore, with some hesitation that I give 

 the animal a name at this time, especially as it inhabits an area 

 not very far removed from that of C luehdorfi. Still, I have the 

 support of Mr. A. D. Bartlett, who saw the specimen in August, 

 and regarded the Woburn deer as undoubtedly re])resenting a new 

 species. In the event of its proving decidedly distinct, the name 

 of Oerviis hedfordianus would be appropriate, and this name I 

 accordiugly assign to it provisionally. 



Whether of individual or of specific value, the late develop- 

 ment of the caudal disk in the summer coat of the second year is 

 certainly a very remarkable feature ; and this feature, together 

 with the bright chestnut-red colour of the coat at the same season, 

 must be regarded as one of the most distinctive peculiarities of 

 this deer. In the winter coat the narrowness and banded coloration 

 of the throat-fringo must likewise be noted as a well-marked featiu-e. 

 Beyond this it is almost impossible to go at present in attempting 

 to define the presumed species. 



It is quite clear that the specimen has nothing to do either with 

 C. davidianus or with the Pseudaxine group. 



The following list of the known species of Elaphine Deer, with 

 a few of their leading distinctive characteristics, may be found 

 useful in connexion with the foregoing notes : —
