The genus Chceronycteris is now for the first time recorded 

 from Trinidad. The present species, while agreeing with C. 

 minor from Surinam in size, appears to differ from it decidedly 

 in coloration, particularly of the underfur, and in the shortness 

 of the thumb, in the greater length of the tibia, and in the cal- 

 caneum being much shorter, instead of much longer than the 

 hind foot. 



While agreeing in the relative length of the calcaneum with 

 C. mexicana, it is widely dissimilar in size, as well as in other fea- 

 tures, it being very much smaller in all parts, as shown by the 

 following comparative measurements : 



In dental and cranial characters C. intermedia appears to agree 

 with C. mexicana and C. minor. The position of the lower pre- 

 molars as shown in Dobson's plate (Cat. Chirop., PI. xxvii, Fig. 6, 

 6a) does not agree, however, with his description given in the 

 text (1. c., p. 510). 



8. Artibeus, sp. nov. ? A large Artibeus, not referable to 

 either A. planirostris or A. perspicillatus, is represented by a sin- 

 gle skin, the skull unfortunately having been stolen by the rest- 

 house cat. It differs in coloration and in the distribution of the 

 fur on the wing-membranes, from any of the currently recog- 

 nized species of Artibeus. The forearm measures 63 mm. ; the 

 third metacarpel, 61, and the tibia, 25.4. Color above and below 

 light brown, much lighter on the head and anterior half of the 

 body, the hairs nowhere tipped with gray. A broad white stripe 

 above and a faint whitish line below each eye. 



9. Lutra insularis F. Cuv. An adult female (No. ffff, 

 fully mature but not aged) gives the following measurements : 



1 Measurements from skin 



2 Measurements from alcoholics. 



3 Measurements from Dobson, Cat. Chirop., pp. 510, 511.
