at base of second premolar 3.8 (3.5-4) ; height of brain-case 8.3 (8-8.8) ; 

 breadth of brain-case above roots of zygomata 9.1 (9-9.2); width of 

 palatal constriction 2.1 (2-2.2); length of palate 9.7 (9.2-10); width 

 of palate (including teeth) 7.3 (7-8); greatest length of mandible 15.4 

 (15-16). 



Remarks. — The Cuban form minor is quite distinct from any of the 

 related forms except the Jamaican Macrotus waterhousii jamaicensis. 

 The specimens from eastern Cuba somewhat approach this latter race, 

 as already noticed by Gundlach {vide supra), but the general charac- 

 ters of the race are retained and the smaller size and weaker teeth, as 

 well as the deeper coloration, will serve to distinguish the two races. 



Specimens Examined. — Twenty-eight; four skins, twenty-four alco- 

 holics :
