that island. Measurements of the male holotype of M. plethodon, 

 taken for us by Gary L. Ranck, plus those given by Miller (1900, 

 p. 38), show that it is somewhat smaller than the other individual, 

 which was collected in 1961. It is purely on the basis of the holotype 

 that we recognize M. p. plethodon as distinct from other Lesser An til- 

 lean populations; the second specimen (also a male) has measurements 

 that fall within the parameters established by other Lesser Antillean 

 Monophyllus; those of the holotype do not. It is possible that Mono- 

 phyllus from Barbados average slightly smaller than their relatives 

 elsewhere in the Lesser Antilles and, for this reason, we accept M. p. 

 plethodon as a distinctive Barbadian subspecies with full cognizance 

 that additional material from Barbados may well demonstrate the 

 incorrectness of this conclusion. 



On the basis of the single fresh male examined, there seem to be 

 no differences in color between M. p. plethodon and the subspecies M. 

 p. luciae that occurs on other Lesser Antillean islands. The recently 

 collected specimen was taken in a mist net set between the buttresses 

 of the road bridge at Jack-in-the-box Gully. The gully is a steep- 

 sided and wooded ravine in an area otherwise devoted to cultivation 

 of sugarcane. Artibeus jamaicensis was the only other bat taken in 

 the gully. 



Specimen examined. — Barbados: St. Thomas Parish: Jack-in- 

 the-box Gully, 1 cf (AS 5302).

Monophyllus luciae Miller, 1902, p. 111. [Type-locality: St. Lucia.] 



Definition. — A subspecies of M. plethodon characterized by a com- 

 bination of large size (total length 69-84), long forearm (40.1-45.7), 

 large skull (greatest length 22.1-24.2), and long toothrows (maxillary 

 toothrow 7.8-8.5). 



Distribution. — Known presently from the Lesser Antillean islands 

 of Anguilla, Barbuda, Antigua, Dominica, and St. Lucia (see fig. 1). 



Remarks. — At the time of its description, M. plethodon was com- 

 pared only with the then-named kinds of Monophyllus — M. redmani, 

 M. portoricensis, and M. clinedaphus. The dental peculiarities (pri- 

 marily the crowding of the upper premolars) used to distinguish M. 

 plethodon from these other taxa do indeed distinguish it from these 

 Greater Antillean bats. When M. luciae was named (on the basis of 

 16 specimens), it was compared with M. plethodon and was said to 

 differ from the latter in being larger (which apparently it is) and in 

 having less crowded teeth. The teeth of our Barbadian specimen, 

 although crowded as typical of the species, are no more closely ap- 

 pressed than in specimens from St. Lucia, Dominica, or other Lesser 

 Antillean islands. Since there are no skins available from St. Lucia,
