In view of the fact that, so far as known, no member of this genus 

 has been taken on the mainland of America, it is probable that this 

 species, described from a single specimen without locality, is likewise 

 Antillean. In size and other characters it approaches nearest to M. 

 redmani of Jamaica. Possibly its home may be looked for in San 

 Domingo.

The Santa Lucia Monophyllus is, as might be expected, "nearly 

 related to that of Barbados. Its larger size and less crowded teeth 

 readily distinguish it." 



Monophyllus plethodon Miller.

The type was collected in St. Michael's Parish, Barbados. It is 

 a strongly characterized species, and, strangely enough, appears to 

 have escaped observation in this thickly populated island until 1899. 



Hemiderma perspicillatum (Linne). 



Vespertilio perspicillatus Linne, Syst. Nat., ed. 10, 1758, 1, p. 31. 



Dobson's (1878, p. 494) statement that this bat occurs "through- 

 out the West Indian islands" is probably based on the fact that he 

 had specimens from the eastern and western extremes of the group, — 

 namely, one each from Grenada and Jamaica. These constitute the 

 only specific records I have found for it in the West Indies. The 

 species is common on the tropical mainland of South and Central 

 America north to southern Mexico. It occurs in Trinidad, whence 

 it may have reached Grenada at times when a connection existed. 

 Its presence in Jamaica may equally be explained by assuming a 

 former connection with the Honduras peninsula. Its case is somewhat 

 paralleled by that of Sturnira lilium, whose range on the mainland 

 probably did not extend sufficiently far to the north to enable it to 

 reach Cuba by a Yucatan connection. 



No critical comparison appears to have been made between speci- 

 mens from Jamaica and the mainland.
