no. 3634 ARDOPS — JONES AND SCHWARTZ 11 



collection of the five specimens listed by Miller (loc. cit.) in the origi- 

 nal description save that they were obtained by H. Selwyn Branch 

 between Jan. 25 and Feb. 1, 1902. Of the other three specimens, 

 Allen (loc. cit.) wrote as follows: "Dr. G. K. Noble, who secured an 

 adult female and well-grown young in Guadeloupe in 1914, writes 

 me that he found these hanging [in a tree?] together directly over a 

 path he was following through the woods near Sainte Rose. Later 

 his guide caught another . . . ." The young bat mentioned was 

 approximately half grown (forearm 34.4) ; the exact date of its capture 

 in 1914, however, is not recorded on the specimen label. 



Specimens examined. — -8. Guadeloupe: Sainte-Rose, 2 (MCZ); 

 no specific locality, 6 (1 MCZ, 5 USNM). 



Ardops nichollsi koopmani, new subspecies 



Holotype. — Adult female in spirits, skullremoved, AMNH 213,951 , 

 from near Balata, Martinique, Lesser Antilles; obtained by Harry 

 Beatty and Peter Martin on Mar. 18, 1967, original no. 656. 



Distribution.— Known only from Martinique (see fig. 3). 



Diagnosis. — -A medium- to large-sized subspecies of Ardops nic- 

 hollsi having a large though relatively narrow skull, well-developed 

 sagittal crest, narrow molariform teeth, and marked sexual dimor- 

 phism; color generally as in A. n. nichollsi, white spot at junction of 

 wing with body prominent in both sexes. 



Measurements. — External measurements of the holotype, another 

 adult female, and two adult males (all taken from specimens pre- 

 served for several months in alcohol) are, respectively: total length 

 70, 68, 67, 65; length of hindfoot 17, 17, 16, 16; length of ear 18.5, 

 18, 18, 17; length of forearm 50.5, 47.3, 47.5, 46.0. See table 1 for some 

 cranial measurements of the holotype and the first-listed male; addi- 

 tional measurements of these two skulls are condylobasal length 21.0 

 and 19.2, and breadth across upper canines 6.2 and 5.1. 



Remarks. — Ardops nichollsi koopmani differs from populations of 

 the species on adjacent islands (A. n. nichollsi to the north on Dominica 

 and A. n. luciae to the south on St. Lucia) in being considerably 

 larger. Judging from the skulls of the male and female available for 

 study, secondary sexual dimorphism is marked in A. n. koopmani in 

 that the cranium of the male is about the size of that of the largest 

 female of the subspecies A. n. nichollsi examined, whereas the cranium 

 of the female holotype is the largest we have studied save for those 

 referred to A. n. montserratensis. Both the male and female of A. n. 

 koopmani have well-developed sagittal crests, reminiscent of some 

 individuals of A. n. nichollsi. Members of the new subspecies are 

 notably smaller and somewhat narrower of skull than specimens of 

 the northerly A. n. montserratensis.
