7. Review of Bats of the Endemic AntiEean Genus Monophyllus 



By Albert Schwartz and J. Knox Jones, Jr. 2 



As recently as 1959, Hall and Kelson (p. 116) commented on 

 the status of the bats comprising the seven species of the phyllosto- 

 matid genus Monophyllus, endemic to the Antillean region: "Some 

 of the species of Monophyllus are known from only one specimen 

 and none is really well represented in collections. Therefore the 

 extent and nature of individual variation is only poorly known. 

 Further, the characters employed to distinguish each of the several 

 species from others are minor differences in proportion that are 

 best appreciated only by direct comparison." Consequently, Hall 

 and Kelson's key to the named species of Monophyllus is based 

 primarily on provenance of the known kinds rather than on mor- 

 phological characteristics; such a course could hardly have been 

 avoided since nowhere are there definitive statements concerning the 

 variation of all the species involved. Miller, the first and only reviser 

 (1900) of Monophyllus, had at that time eight specimens. From
