The type of fuliginosa is still in the British Museum and I am 

 indebted to Mr. Oldfield Thomas of that institution for notes 

 and a figure of the nose pad, which prove its relationship is not 

 with macleayii. A representative of this small species is found 

 in Cuba, and was lately described by the writer (1916) as torrei ; 

 it should best be considered as a subspecies of fuliginosa. No 

 corresponding form has as yet been discovered in Jamaica, nor 

 in Porto Rico unless C. inflata eventually proves to be of this 

 group rather than a form of macleayii. 



The third species is the largest of the three, and was first de- 

 scribed from Jamaica as Phyllodia [=(7.] pamellii by Gray in 

 1843. Gundlach, in 1861, found a very similar form in Cuba, 

 to which he gave the name boothi, very properly made by Rehn 

 (1904) a subspecies of the Jamaican animal, C. pamellii boothi. 

 A third form, smaller than either of the others, was described 

 by Miller, in 1902, from Porto Rico, as portoricensis. This author 

 gives a key to the forms of pamellii, based on the relations of 

 the small second lower premolar, which he states in the typical 

 subspecies does not appear in profile view from the external 

 side, since the first and second premolars meet and crowd it 

 inward from the tooth row. This condition I did not find in 

 the two Jamaican specimens I examined. In both there was a 

 small space between the first and third premolars, in which the 

 small second tooth was visible. 



It is of much interest to record the discovery of a form of C. 

 pamellii from Santo Domingo, where in his expedition of 1916, 

 Mr. J. L. Peters captured three in a cave. These prove to be very 

 different from the forms of the other islands. They are much 

 less in size, with smaller ears, in these respects resembling more 

 the Porto Rican form, but are even smaller. It seems therefore 

 of particular significance that, as in case of the Erophyllas, the 

 Porto Rican and Santo Domingan races more nearly resemble 

 each other than they do those of Cuba and Jamaica, which latter 

 again are closely similar. 



A description of the Santo Domingan bat follows:
