This species, which is the largest, and one of the most common of the 

 American Nose-leaved Bats, varies considerably in colour. The variation may 

 depend on the season of the year, or on local peculiarities, but certainly not on 

 sexual distinction, for the specimens of the same sex are not similar in this 

 respect. Thus, some males are nearly black, and bright rufous beneath, while 

 others, which are more rufous above, are grey beneath ; and a female from the 

 same locality is rufous on the back, and rufous-grey on the under side. 



All the varieties may always be distinguished by their more rufous colour, 

 and rather larger size, from P. fuliginosum {Gray, Mag. Zool. and Bot. ii. 6.), 

 which is the only species that can be confounded with it, on account of the 

 stoutness of the body and general size of the species, which more nearly re- 

 semble those of the Pteropi, than any other known Bats.
