1904.] NATURAL SCIENCES OF PHILADELPHIA. 189 



Distribution. — The island of Haiti and San Domingo. No specimens 

 possessing exact data available. 



General Characters. — Allied to the Cuban macleayii but the size 

 smallest in the genus, skull smaller than in macleayii and compara- 

 tively slender, and calcanea shorter. 



Head. — As in C. macleayii. 



Limbs. — Except for the generally smaller size of the forearm and 

 tibia, no difference is noted from the same portions of macleayii. The 

 calcaneum is distinctly shorter, not at all or but slightly exceeding 

 the tibia in length. 



Membranes and Fur. — As in macleayii. 



Color. — The available alcoholic specimens have been preserved for 

 quite a long time and the coloration exhibited by them may be some- 

 what abnormal. General color above cinnamon-rufous; below seal- 

 brown; volar membranes prout's-brown ; ears wood-brown. The 

 single skin available is mummified and has been in a liquid preserva- 

 tive at some time ; the colors are as follows : above pale mars-brown ; 

 below isabelline, becoming ecru-drab on the throat; membranes drab. 



Skull. — Similar to C. macleayii but smaller, the males with the whole 

 form comparatively more robust than in the same sex of macleayii. 

 The singular abbreviate skull of the females of macleayii approaches 

 m. fuliginosa very much, but the latter has a slenderer rostrum and 

 more compressed zygomata. One specimen (5072, A. N. S. P.) bears 

 a comparatively high sagittal crest. 



Teeth. — Essentially as in C. macleayii with the following exceptions : 

 first upper premolar simpler in outline, more ovate than reniform; 

 second upper premolar more transverse in outline than pentagonal, 

 the anterior shoulder not as strongly developed as in macleayii. 



Measurements. — Average of series: Total length [1] 56.2 mm. ; length 

 of head and body [3] 40.5 (39.5-41) ; head [1] 17.1 ; ear [2] 13.6 (13.2-14) ; 

 tragus [2] 4.5; forearm [5] 37.7 (35-40); thumb [4] 6.2 (6-7); third 

 digit [5] 62.2 (58.5-68); tibia [5] 15.1 (14.5-16); calcaneum [2] 15 

 (14-16) ; foot [5] 8.3 (8.9) ; tail [5] 18.8 (17-20). 



Total length of skull [2] 14.1 (14-14.3) ; greatest zygomatic width [1] 

 7.2 ; interorbital width [3] 3 ; height at base of second premolar [3] 3 ; 

 height of brain-case [2] 6 ; width of palatal constriction [2] 1 .4 ; length of 

 palate [2] 6.1 (6-6.2); width of palate including teeth [3] 5.1 (5-5.2); 

 greatest length of mandible [2] 10.5 (10-11). 



Remarks. — This form of macleayii, while not at all sharply defined, 

 can be recognized by the unusually small size, short calcaneum and 

 rather different skull. In a number of characters which reach their 

 extremes in macleayii and m. inflata, m. fuliginosa is intermediate, as
