Glossophaga rostrata sp. nov. 



Type. — Adult male (skin and skull), No. 111,500, U. S. National 

 Museum. Collected on the Westerhall Estate, Grenada, Lesser Antilles, 

 August 25, 1H00, by Peter Gellineau. Original number, 29. 



Diagnosis. — Externally like Glossophaga longirostris Miller, but- 

 general color averaging slightly less dark. Skull without appreciable 

 peculiarities as compared with that of the mainland animal. Teeth 

 differing from those of G. longirostris in the deeper emargination of m' 

 and m 2 , as a result of which the postero-external prolongation of crown 

 i metastyle and base of metacone) is more sharply defined, while the 

 main portion, bounded on outer side by paracone and point of metacone, 

 and on inner side by protocone and its commissure, assumes a general 

 outline that is almost square; last two lower cheek-teeth shorter than iu 

 G. longirostris, a peculiarity especially noticeable in m a . 



Measurements. — Type: tibia, 15; foot, 10.0; forearm, 37.4; thumb, 9.0; 

 third finger, 82; fifth finger, 53; condylobasal length of skull, 21.8; 

 zygomatic breadth, 10.0; rostral breadth across bases of canines, 4.0; 

 breadth across interorbitral swellings, 5.2; mastoid breadth, 0.0; breadth 

 of braincase, 9.0; depth of braincase, 7.0; mandible, 14.8; maxillary 

 toothrow exclusive of incisors, 8.0; mandibular toothrow exclusive of 

 incisors, 8.4. 



Specimens examined. — Fourteen, all from the type locality. "Taken 

 in hollow tree." 



Remarks. — The Grenadan form of Glossophaga, though not conspicu- 

 ously differentiated from the mainland representative of the longirostris 

 group, has very constant characters in the outlines of the molar crowns. 

 The skull shows no tendency toward the narrowing characteristic of the 

 Curacaon G. elongata or the reduction in size peculiar to the Jamaican 

 G. antillarum. Two skulls of immature individuals taken by Mr. Gelli- 

 neau at Roseau, Dominica, are not in condition for positive identification. 

 They agree in dental peculiarities with the Grenadan form. 



Brachyphylla minor sp. nov. 



Type. — Adult female (in alcohol), No. 101,528, U. 8. National Museum. 

 Collected in Coles Cave, St. Thomas Parish, Barbados, Lesser Antilles, 

 June 14, 1899, by P. McDonough. 



Diagnosis. — Like Brachyphylla cavernarum Gray,* but size at and below 

 the minimum; area of cheek-teeth reduced. 



Measurements. — Type: head and body, 78; tibia, 25; foot, 17; forearm, 

 61.5; thumb, 15; third finger, 105; fifth finger, 80; ear from meatus, 20; 

 width of ear, 13.5; condylobasal length of skull, 20.6; zygomatic breadth, 

 16.0: breadth of braincase, 12.0; mandible, 19. 8; maxillary toothrow 

 exclusive of incisors, 10.4 ; mandibular toothrow exclusive of incisors, 11.0. 



* The United States National Museum contains about 200 specimens of true caver- 

 narum, representing the islands of St. Vincent (type locality), St. Lucia, Dominica, 

 Montserrat, Antigua, Barbuda, and Porto Rico. Practically all are preserved in 

 alcohol. I have not been able to discover any characters to distinguish local forms.
