ALLEN: MAMMALIA. 205 
Hydropotes kreyenbergi on the basis of a single male skull, unaccompanied by 
skin, from Hankow, also on the Yangtze, in east central Hupeh. Our specimens 
should thus be referable to the latter species if it is really distinct, but this does 
not seem clear from the material at present available. Hilzheimer bases his 
distinction on slight cranial differences, which may be more or less individual 
and which are mainly derived from a comparison of figures. These differences 
are chiefly :— (1) in inermis the rostral portion of the skull in front of the orbit 
is about thrice the length of the orbit, while in kreyenbergi it is but 23 times this 
distance; (2) the least breadth of the combined nasals is in inermis somewhat 
more than # their greatest combined breadth; whereas in kreyenbergi they are 
so narrow that their least combined breadth is at most equal to one half their 
greatest combined breadth; (3) in kreyenbergi the upper rim of the orbit is so 
protuberant that in profile view it hides the median roof of the skull at that 
point, which is not the case in inermis. 
In the skulls from Hupeh, these characters are not borne out. Thus in a 
male from Kwangtitze, the nasals are hardly narrowed distally and at the narrow- 
est point their combined breadth is exactly three fourths the total width at 
the widest point as in inermis. The orbit is contained three times and a slight 
fraction in the length of the preorbital part of the skull, and the upper orbital 
rim is on a level with the interorbital parietes. The series shows more or less 
individual variation in all these characters, and the females as a rule have rather 
narrower nasals and a more compressed rostrum than the males. Unless there- 
fore, other characters can be discovered, the water deer of the upper and the 
lower Yangtze must be considered identical. 
Moscuus siIranicus Biichner. 
Owing to ceaseless persecution by the Chinese, the Musk deer has been 
nearly exterminated in the country where Mr. Zappey collected. The musk 
glands are keenly sought and much esteemed by the Chinese. In the moun- 
tains of western Szechwan, at Shuowlow, a single male was shot at an altitude 
of 14,000 feet. Although others were seen they were so shy that it was impossible 
to approach within range. 
SUIDAE. 
Sus MouPINENSIS Milne Edwards. 
Near Tachienlu, in western Szechwan, the skull of a wild pig was procured, 
which undoubtedly represents Milne Edwards’s Sus moupinensis. The skull is
