278 COLLECTION OF BATS, 
NOTE XLI. 
ON A COLLECTION OF BATS FROM THE 
WEST-INDIES. 
BY 
Dr. F. A. JENTINK. 
September 1893. 
The collection of Bats hereafter described has been pre- 
sented to the Leyden Museum by our well known corres- 
pondent Dr. OC, G. Young from Berbice, New Amsterdam, 
British Guyana. 
This collection tells us that, although our knowledge 
about the Bats may have increased during the latest years, 
much remains to be done before we can pretend to know 
exactly these most interesting creatures: especially the 
study of the South-American Bats is very difficult by lack 
of sufficient material. Therefore every addition may be 
called welcome. 
The specimens contained in this collection have been 
preserved in alcohol and are all in perfect condition; they 
are eighty in number and belong to seventeen species, 
among which several rare and interesting ones and one 
new species, 
Atalapha intermedia Allen. 
Two female-specimens. 
In comparing our specimens with the specimen descri- 
bed and the head figured by Dobson (Catalogue, 1878, p. 
274, pl. XVI, fig. 3) we find an important difference in 
Notes from the Leyden Museum, Vol. XV.
