greatest length of skull (lower extreme in M. r. redmani 22.8, high 

 extreme in all other subspecies 22.4). Other skull measurements 

 (condylobasal length, postorbital constriction, mastoidal breadth) 

 show some degree of overlap but length of maxillary toothrow (8.3- 

 8.9 in M. r. redmani, 6.8-8.3 in other races) is almost as effective as 

 greatest length of skull in distinguishing the nominate subspecies. 

 Of external measurements, the total length of M. r. redmani is greater 

 (73-80) than that of the other tw r o subspecies (59-71), and measure- 

 ments of ear from notch lie at the upper extreme for the species. 

 Mensural data are given in tables 1 and 2. 



The senior author took four specimens of M. r. redmani from a 

 large cave at Windsor, Jamaica, where the bats were observed clinging 

 to and flying just below the high ceiling of the moist cave, well back 

 from the entrance. Koopman and Williams (1951, p. 20) recorded 

 Monophyllus in surface and subsurface deposits in Jamaican caves, 

 but not as fossils: these authors regarded M. redmani as common in 

 Jamaica today (p. 23). Williams (1952) reported Monophyllus from 

 the "bat layers" of a single cave at Portland. No information has 

 been published on weights or dates of parturition.

 Cave, Balaclava, 2^,39 (AMNH 45233, 45236-39). Trelawny

 Cave, 3 cf , 1 9 (AS 5248-51) ; no specific locality, other than Jamaica, 

 1 cf (MCZ 45778).

Monophyllus clinedaphus Miller, 1900, p. 36. [Type-locality: unknown, herein 

 restricted to the vicinity of Baracoa, Oriente Province, Cuba.]

 Province, Cuba.] 



Monophyllus cubanus ferreus Miller, 1918, p. 40. [Type-locality: cave eight 

 miles west-southwest of Jer^mie, Departement du Sud, Haiti.] 



Distribution. — Cuba and Hispaniola; on the latter island ap- 

 parently as yet unknown in the Dominican Republic (see fig. 1). 



Definition. — A subspecies of M. redmani characterized by small 

 body size (total length 59-70, mean 65.5 for six Cuban specimens 

 and 60.7 for three Hispaniolan specimens), relatively long forearm 

 (37.6-42.5, mean 40.1 for 32 Cuban specimens and 39.8 for 24 His- 

 paniolan specimens), skull of moderate size (greatest length 21.0- 

 22.1, mean 21.9 for nine Cuban specimens and also for four Hispanio- 

 lan specimens) with broad postorbital region, moderately broad 

 mastoid region, and narrow zygomata, and moderately long toothrows. 

 The color is brownish, generally paler than in M. r. redmani. 



Remarks. — Monophyllus clinedaphus was described by Miller 

 (1900, p. 36) on the basis of a single male in alcohol with skull re-
