set straight parallel short hairs, forming a comb-like fringe. Be- 

 neath, the wing-membrane is clothed with very fine rather long hairs 

 as far as a line joining the elbow- and knee-joints ; the remainder of 

 the membrane is naked, except where a few very short, almost invi- 

 sible hairs arise from the transverse dotted lines. 



Upper incisors slender and very acutely pointed ; the inner incisors 

 not so much curved forwards as in K. picta, with a minute basal 

 cusp posteriorly not visible from without ; outer incisor unicuspi- 

 date, nearly as long as the inner incisor ; first and second upper pre- 

 molars smaller in proportion to the other teeth than in other species 

 of the genus, the second premolar less than the first in cross section 

 at the base.

Hah. S.E. Africa (Shupanga, near the Zambesi River ; east coast 

 of Cape Colony). 



Dr. Kirk found a colony of this species inhabiting the hanging 

 nests of "Weaver-birds at Shupanga.

(Type of Nycticejus nidicola, Kirk;) 



Under the name of Kerivoula argetitata Mr. Tomes has described 

 (P. Z. S. 1861, p. 32) a species from Otjoro, S.W. Africa, which, 

 judging from the description, appears to be an example of an old 

 individual of K. lanosa or, at most, a local variety of that species. 

 The ears and tragus, the distribution of the fur and the teeth, are 

 quite as in K. lanosa, the only difEerences being that the single spe- 

 cimen on which Mr. Tomes has founded his species has the forearm 

 one tenth of an inch longer, and the extreme tips of the fur are of 

 a " shining and silvery white."

 oval, close together, opening near the margin of the lip ; lower lip
