1905. ] OF THE GENUS RHINOLOPHUS. 111 
Details—(1) Compared with tragatus: On an average (as a 
rule also absolutely) markedly smaller: forearm 57:2-59-3 mm. 
(tragatus: 59-63); but the horse-shoe is, nevertheless, of 
the same excessive breadth: 9-9°5 mm. (éragatus: 8°8-9°7), 
Skull considerably smaller and narrower, but {(in conformance 
with the broad horse-shoe) with rather broad nasal swellings: 
comparatively as broad as in tragatus, but, owing to the smaller 
size of the skull, not absolutely so. Teeth markedly smaller, the 
tooth-rows shorter. 
(2) Compared with regulus: Of approximately the same size 
(or nippon rather smaller), but horse-shoe considerably broader : 
9-95 mm. (regulus: 8:2-8°8). Skull generally smaller and 
narrower, but nasal swellings, nevertheless, quite as broad as 
in regulus (comparatively, therefore, decidedly broader). Tooth- 
rows markedly shorter. 
(3) Compared with the western races: The broad horse-shoe 
prevents it from being confused with any of the western forms. 
Colour. AS im adult individuals of Serrum-equinum from 
Europe*. No quite young specimens examined. 
Dentition (5 skulls). In two skulls p, is present on both sides; 
in two (teeth unworn) on one side only; in one (teeth very 
slightly worn) lost, but the alveoli not quite obliterated. p? is 
present in all skulls examined. The cingula of the upper canine 
and p* not only less completely overlap than is generally the 
case in the other races, but in one skull the two teeth are very 
slightly, in one quite distinctly, separated. his dentition is 
decidedly more primitive than in the western neighbours of this 
race, tragatus and regulus. 
Distribution. S. China (Shanghai). Pt. Hamilton. Japan. 
Remarks. 1 find the examples from Shanghai and Pt. Hamilton 
(S. of Korea) indistinguishable from those from Japan.

* According to Temminck the fur of nippon is “plus long, plus abondamment 
feutré, plus soyeux et moins lustré” than in ferrwm-equinwm from Europe, and the 
colours “ différent également.” In the length and abundance of the fur I am unable 
to find any tangible difference between nippon, tragatus, and ferrum-equinum. As 
to the colours (two well-preserved skins: Fuji and Nikko), it is quite the same 
as in darker individuals of ¢ragatus, and this again as im-fully adult individuals of 
the typical ferrum-equinum ; laid side by side these Bats are indistinguishable in 
colour,
