MOLOSSUS TROPIDORHYNCHUS Gray. 

 1839. Molossustri)pl(lnrliij)irhtis(}R.\y, Ann. Nat. Ilint., IV, p. 6, September, 1839. 



Fourteen skins and eleven iilcoholic specimens from Pinar del Kio, 

 and five (8 skins) from El Cobre. This is the Cuban representative 

 of Ifolossus ohscurus. It is readily distinguishable from the South 

 American species by its much smaller size. For measurements see 

 table, page 340. 



Field notes. — Probably the most abundant of the species living 

 together under a tile roof at Pinar del Kio. Like the others they 

 emerge suddenly from their roosting place very late in the dusk of 

 evening, and after flitting a few times about the roof are gone. 

 At El Cobre the specimens were likewise collected under the tiles of a 

 roof. — W. Palmek.

One specimen (in alcohol) was taken under a tile roof at Pinar del 

 Rio, February 27, 19(»0. For measurements see table, page 340.

Three in alcohol and five skins from El Guama, one skin from Caba- 

 nas, and one (in alcohol) from Pinar del Rio. 



This species is readily distinguishable from both Nyctinmnus hasi- 

 liensis and JS^. cynocephalus by its small size, the character pointed out 

 by Gundlach in the original description, A further peculiarity of the 

 Cuban animal, apparently shared b}' all the AV^est Indian memb(>rs of 

 the group, is the minute size and rudimentar}^ structure of the first 

 upper premolar. In the continental species this tooth is well ihnel- 

 oped and provided with a distinct cingulum, Avhile in the insidar forms 

 it is a mere terete spicule. For measurements see table, page 840. 



Field notes. — Occasionally seen about dark among the hard lime- 

 stone hills of the mountainous districts. Here it spends the day in 

 the smaller crevices of the caves, with Artlheus j)ari'ijk-'<. We could 

 find none during the day, although the Aj'fiheus was common and con- 

 spicuous, ])iit by closing all but one of the entrances to a cave and 

 hanging a tine net over this opening at night we usually obtained one 

 or more of these little bats the next morning. The specimen from 

 Cabanas was captured in a house. — W. Palmku.
