by more than 6 mm. Its skull is large and heavy, and its 
cranial ridges far more developed than in specimens of similar 
age of the allied forms. In company with it there lives the 
smallest eastern species, 2. minor, such a difference in size no 
doubt tending to reduce competition, and therefore to enable 
such closely allied forms to live side by side. 
h. shortridgei must be exceedingly rare, as getting all the fine 
series of bats now enumerated, including 34 of the previously 
almost unknown ft. minor, My. Shortridge only obtained one 
single specimen of it.

This species has not hitherto been represented in the Museum 
collection, the only known example of it being the type, preserved 
in the Calcutta Museum. The present fine series of topotypes 
is therefore a most valuable accession to the National Collection. 
“ «Tiddot’ (Javanese) (as distinguished from insectivorous 
bats). 
“The smaller fruit-bats are really much more plentiful than 
Pteropus vampyrus, but on account of their smaller size and 
late appearance in the evenings they are less noticeable. They 
also seldom roost by day in conspicuous positions, but generally 
collect in caves, hollow trees, or among dense foliage. When 
disturbed by day they will dart off sharply in every direction 
like insectivorous bats. The fruit-bats are a very serious pest 
in Java, on account of their enormous numbers, and it is chiefly 
on their account that so much of the fruit is picked green and 
not allowed to ripen on the trees.”—G. C. 8.

The Buitenzorg specimens are absolute topotypes of this fine 
- species, which had not previously been represented in the Museum 
collection, 
Young specimens of (1. titthecheilus are of a brownish-grey 
colour, and in other respects have a general likeness to Rousettus, 
for members of which genus they were at first mistaken.
