grove, and eight were netted in company with Artibeus, Brachyphylla, 

 Monophyllus, and Sturnira over a rock-strewn gravel bar between the 

 edge of the Layou River and lush vegetation that lined the bar. 

 A female from 1 mile northwest of Portsmouth was taken in a net 

 stretched across a trail on the side of a hill overlooking the Caribbean 

 in dry, relatively scrubby forest; another female captured near the 

 same place in 1964 was netted near the ruins ("Cabrit") on Prince 

 Rupert Bluff. A male from 6 miles northeast of Roseau was netted in 

 1962 over a stream in rain forest, whereas a female from Roseau was 

 trapped along with several Artibeus jamaicensis in a net placed ad- 

 jacent to a pond in the Botanic Garden. 



Each of six females collected in the spring of 1966 was reproductively 

 active. One taken on April 19 was lactating. The others each carried 

 a single embryo on the following dates (crown-rump length of embryos 

 in parentheses): March 27 (11); March 28 (21); March 29 (31); 

 April 2 (18); April 14 (29). Testes of March- and April-taken males 

 varied in length from 4.5 to 6.0. Wing mites (Spinturnicidae) and hair 

 mites (Listrophoridae) were obtained from several individuals, but no 

 other kinds of ectoparasites were found. 



Specimens examined. — 46. Dominica: "Cabrit" [northwest 

 of Portsmouth], 1 (USNM); 1 mile northwest of Portsmouth, 100 

 ft, 1 (KU) ; Clarke Hall Estate, 100 ft, 9 (KU) ; 6 miles northeast of 

 Roseau, 1 (AS) ; Roseau, 1 (USNM) ; Botanic Garden, Roseau, 50 ft, 

 1 (KU); no specific locality, 2 (1 MCZ, 1 BMNH— examined for us 

 by J. E. Hill). 



Ardops nichollsi mont serratensis (Thomas) 



Stenoderma montserratense [sic] Thomas, 1894, p. 133. 

 A[rdops]. montserratensis.' — Miller, 1906, p. 84. 



Holotype. — Adult male in spirits, skull removed, BMNH 94.1.9.1, 

 from unknown locality on Montserrat, Lesser Antilles. 



Distribution. — Known from Montserrat and St. Eustatius (see 

 % 3). 



Measurements. — External measurements taken from a male and 

 female preserved in alcohol from St. Eustatius are, respectively: total 

 length 69, 72; length of hind foot 18, 17; length of ear 18, 18; length of 

 forearm 51.1, 51.9. The male holotype, also in alcohol, was recorded 

 in the original description as measuring : head and body [total length] 

 69; length of ear 16.5; length of forearm 51.5. See table 1 for cranial 

 measurements. 



Remarks. — Ardops nichollsi montserratensis is so much larger than 

 the holotype of A. n. nichollsi that it is easy to understand why 

 Thomas (1894, p. 133) named it as a full species. The subsequently 

 described subspecies on Guadeloupe, Martinique, and St. Lucia
