ALLEN: MAMMALIA. 243 
About the eye is a narrow ring of hair-brown, and a few dark brown hairs are 
scattered along the sides of the body. Without additional specimens it is im- 
possible to decide how great may be the individual or age variation in color so 
for the present it seems best to consider this Ichang specimen as representing 
E. hanensis. The collector's measurements are: — total length, 225 mm.; 
tail, 19 mm.; hind foot, 43 mm. 
The skull seems to be that of a nearly adult animal, and is but a trifle smaller 
than that of EH. dealbatus from Pekin. Its dimensions are:— greatest length, 
* 49.5; basal length, 46; palatal length, 29; zygomatic breadth, 30; mastoid 
breadth, 24; width outside first upper molar, 20; mandible from condyle to tip 
of incisor, 39; upper tooth row, 27; lower tooth row, 25.5. The anterior pro- 
longations of the frontals do not reach the intermaxillaries so that there is a 
maxillonasal suture of some 3.5 mm. in length. 
VESPERTILIONIDAE. 
PIPISTRELLUS ABRAMUS (Temminck). 
Between July 24 and August 5, 1907, a series of twenty-five specimens was 
collected at Ichang. A number of these are immature with the metacarpal 
epiphyses still distinct. The species was also obtained at Kiating, Hochinghsien 
and Kweifu, in Szechwan. The adult males are nearly hair-brown above and 
females are of a redder tinge, nearly ‘Prout’s brown.’ In both sexes the bases 
of the hairs are darker, near seal-brown. This sexual dichromatism was noticed 
by Swinhoe (1870, p. 618) who says that ‘“‘the female is a rich brown, with lighter 
and dusky underparts; the male is black.”’ The skulls of our series show some 
variation in size, though this is often more apparent to the eye than the measure - 
ments would indicate. Thus the smallest skull is 13 mm. long but is in every way 
lighter and more delicate than the largest which measures 14 mm. In some the 
upper canine and pm® actually touch, while in others there is a considerable 
space between the two teeth. Usually, however, this space is slight. 
VESPERTILIO MURINUS SUPERANS (Thomas). 
One male was taken at Ichang, Hupeh, April 22, 1907, and a pair on March 
28, 1908, at Kweifu, in eastern Szechwan. 
NycTALUS NOCTULA LABIATA (Hodgson). 
An immature skin and skull from Ichang, July 21, 1907, and an adult skin 
from Kweifu, eastern Szechwan, March 28, 1908, represent a very dark colored
