the wings lighter apically, becoming yellowish white at the extreme 

 tips. Wing membrane from the base of the toes. Proximal two 

 thirds of fore arm above and tipper surface of tibia heavily furred; 

 interfemoral membrane wholly naked below, as are the wing mem- 

 branes, except a narrow band of thin woolly fur along the proximal 

 half of the forearm. 



Measurements (from dry skin). Forearm, 71 mm.; third finger: 

 metacarpal 69, first phal. 24, second phal. 39, third phal. 24; tibia, 26; 

 hind foot, 19; tragus, 4; nose leaf, 6x n. Skull: total length, 32; 

 zygomatic breadth, 18.5; width of rostrum at canines, 9; width of 

 braincase, 14; width at first molars, 14; postorbital constriction, 7. 

 The braincase is gently convex, long, and low. 



This species is nearly related to A. palmarum of Trinidad 

 and adjoining parts of northeastern South America, but 

 differs in the lower, less convex, and more spreading braincase, 

 broader palate and heavier dentition, the upper toothrow 

 (canine and molar-premolar series) having a length of 11.5 

 mm. against 10.2 in A. palmarum; also in more prominent 

 face stripes and darker general coloration. 



It needs no comparison with any of the much smaller West 

 Indian species, nor with A. intermedius of Costa Rica, char- 

 acterized also by small size, but especially by a short, high- 

 arched skull. 



Artibeus insularis, sp. nov. 



Type, No. 19579, $ ad -> Island of St. Kitts, W. I. 



Size large; coloration pale, including membranes. Dorsal surface 

 pale reddish brown, paler below; membranes pale brown; no head 

 stripes. Nose-leaf large. 



Measurements (alcoholic specimen). Head and body, 82 mm. ; nose- 

 leaf, 13.5 x 8; width of interfemoral membrane, 13; ear from crown, 

 15; forearm, 61; thumb, 15; third metacarpal, 58; third finger, first 

 phal. 1 8, second phal. 40, third phal. 20; tibia, 25.5; foot, 16.5. 

 Skull (imperfect): Width across m 2 , 13; width of rostrum at base 

 of canines, 8.6; upper toothrow (c-m 2 ), n ; length of lower jaw, 19.6; 

 height at coronoid, 8; toothrow, n. 



Based on a single alcoholic specimen, a very old male, in 

 excellent preservation, but with the skull badly broken. In 

 external measurements it agrees very well with A. jamaicen- 

 sis, in which the forearm ranges in five adults from 60-62
