1904.] NEW SPECIES OF TUFTED DEER. 169 



makes a much nearer approach than it does to that of E. michi- 

 anus, showing a similar conformation of the bones below the 

 orbit, and apparently also a very similarly shaped preorbital 

 cavity. The nasal bones are, moreover, of much the same 

 relative length, their long diameter being one third of the basi- 

 cranial length. On the other hand, E. cephalopht(,s is at once 

 distinguished by its greatly superior size, as is shown by the 

 following table of the basicranial lengths of the four skulls 

 available for compaiison : — 



E. michianus, male 6| inches 



„ female G^j ,, 



Ichang adult male 6| ,, 



E. cephalofjhiis^ female 1\ „ 



From this it is obvious that the Tibetan skull cannot possibly 

 be the female of the form indicated by the adult Ichang specimen. 



If a male skull of E. cejihalophus were available for comparison, 

 I have little doubt that important differences between it and the 

 Ichang specimen might be detected. As it is, the former species 

 appears to have a much longer type of skull than the Ichang 

 animal, from which it is also distinguished (so far as can be 

 determined) by the much more solid structure of the walls of 

 the preorbital cavity. 



In any case, the Ichang Deer is broadly distinguished from the 

 Tibetan Elajyhochis cephaloplius by its greatly inferior size. 



The foregoing differences seem to leave no doubt as to the 

 specific distinctness of the Ichang Tufted Deer, which may be 

 named Elaphodus ichangensis [cf. Abstr. P. Z. S. 1904, No. 9, 

 p. 10, June 14). It is characterised, as compared with E.'michianus, 

 by its darker and more uniform colour, whiter tail, smaller antlers, 

 larger tusks, shorter nasals, and smaller, deeper, and more evenly 

 circular preorbital fossa ; while it is smaller than E. cephalophus. 



The type will be the aforesaid adult male skull, collected by 

 Mr. Styan. 



In conclusion, I may take the opportunity of referring to the 

 skull of a female Tufted Deer (B.M. No. 98.3.7.18) obtained, 

 together with the skin, by Mr. C. B. Rickett at Fing-ling, Fokien, 

 lying considerably to the south of Ningpo. This skull is of the 

 same general type as that of the female of E. michianus, but 

 differs by its superior size, the basicranial length in the two 

 specimens being respectively 6| and 6^ inches. The Fokien skull 

 is further distinguished by the less marked elevation of the 

 hinder half of the frontal region, Avhich does not develop a 

 median crest, and by the expansion and flattening of the platform 

 formed by the base of the preorbital cavity and the anterior 

 zygomatic root. There are also differences in the form of the 

 paroccipital process in the two skulls, which, with other details, 

 and their marked difference in size, appear to justify the reference 

 of the Fokien Tufted Deer to a separate race, under the name of 

 Elaphodus micltianus fociensis.
