Serotine. 
Teeth very much as in the Serotine. Inner upper incisors 
bicuspid, outer minute. Lower incisors tricuspid, overlapping, 
their line more directly transverse and less angular than in 
the Serotine. Anterior lower molar slightly smaller in pro- 
portion to the second than in the allied species.

Type. Female in spirit. B.M. no. 88.5.17. 3. Presented 
by the late Dr. G. E. Dobson. 
The characters of this species are strongly confirmatory of 
the view that ‘ Hptesecus”’ should not be separated from 
Vespertilio, for with the large size, heavy build, and more or 
less the crested skull of the former it has the broad tragus of 
he typical Vespertilio. 
V. megalurus, the only other African species as large as 
V. platyops, has unicuspidate middle upper incisors. 
Vespertilio minutus somalicus, subsp. n. 
Closely allied to the typical V. minutus, Temm., but 
distinguished by smaller size, at least of head, and much 
paler coloration. 
General characters as in V. minutus, the description of that 
animal in Dobson’s Catalogue agreeing in all details except 
those referring to colour, though it may be also noticed that 
the inner margin of the ear, instead of being “‘ slightly convex 
to the tip,” is flat or even faintly concave for its middle 
third. 
General colour of fur above dull buffy, the hairs blackish 
slate for two thirds of their length, with their tips buffy ; 
beneath the bases are equally dark, the tips being dull 
whitish. Hairs of back rather more than 6 millim. long, 
Wing-membranes smoky brown, interfemoral membrane 
paler brown, both prominently edged with whitish, recalling 
the white edging of Pipistrellus Kuhlii on the same parts. 
Skull very small and delicate, smaller than South-African
