Among named subspecies, A. n. koopmani most closely resembles 

 A. n. annectens of Guadeloupe. Cranially, the one male examined is 

 comparable in overall size with two males of A. n. annectens studied, 

 but it is narrower relative to length of the skull and has a better 

 developed sagittal crest. The female holotype has a longer forearm and 

 longer, relatively narrower skull (excepting zygomatic breadth) than 

 any of the females of A. n. annectens examined and, in direct compari- 

 son with a large female A. n. annectens (MCZ 15927), has narrower 

 molars and a better developed sagittal crest. The two subspecies are 

 separated geographically by the much smaller race A. n. nichollsi of 

 Dominica, and we assume, therefore, that the general resemblance in 

 size has evolved independently. 



Ardops was unknown from Martinique until five specimens were 

 collected there in March of 1967 for the American Museum of Natural 

 History by Harry Beatty and Peter Martin, supported by a grant from 

 the Explorers Club. All the bats were captured near Balata "in mist 

 nets set over streams in second-growth (about 40 years old) montane 

 rain forest" (Karl F. Koopman, pers. comm., May 25, 1967). We take 

 pleasure in according patronymic recognition to Dr. Koopman for his 

 generosity in making the specimens from Martinique available to us 

 for study and also for his contributions to chiropteran biology in the 

 Caribbean region.
