The external characters of BracbyphySla nana Aliller." 



The United States National Museum has recently procured by ex- 

 change -with the Field Columbian Museum two complete specimens of 

 Brachyphylla nana from a cave on the south coast of the Province 

 of Santiago, Cuba. As this bat was originally described from an 

 imperfect skull (Miller, Proc. Acad. Nat. Sci., Philadelphia. 190-?. 

 p. 409. September 12, 1902) the external characters of the species 

 have hitherto been unknown. In general appearance the Cuban ani- 

 mal resembles true BrarJiyphylla cavernaTuvi from St. Vincent more 

 closely than the peculiarities of its skull would lead one to expect. The 

 only tangible difi'erences appear to be the smaller general size of the 

 Cuban species, and its broader, flatter noseleaf. The light basal area 

 of the fur is grayish white in B. nana and dirty yellowish Avhile in the 

 specimens of B. cavernarum that I have examined, but as all have been 

 submitted to the action of preservative fluids this seeming difference 

 may have no real basis. Measurements of an adult female of each spe- 

 cies (those of B. ca'cemarv.m, in parenthesis): head and body, 83 (93): 

 tibia, 25 (29); foot, 15 (18.6); fofearm, CO (06); first digit, 12.4 (16): 

 second digit, 48 (53) ; third digit, 102 (115) ; fourth digit, 80 (92) : fifth 

 digit, 80 (88) : ear from meatus, 22.6 (23) : ear from crown, 17 (18) : 

 width of ear. 14 (15).— 6'tTrrt H. Miller, Jr. 



An overlooked specimen of Chilonycteris psilotis. 



In 1878 Dobson described an American bat as Chilonycferis pnilotis, bas- 

 ing his account on two specimens without history- in the British Museum 

 (Catal. Chiropt. Brit. Mus., p. 451. pi. XXIII. fig. 2). Apparently noth- 

 ing more has been published about the animal. While re-arranging 

 some bats in the United States National Museum I recently found an 

 adult male of this species, (No. 9870), collected in 1858 by Dr. F. Sum- 

 chrast, on the Isthmus of Tehuantepec, Mexico. Its characters agree in 

 all respects with those given by Dobson, except that the forearm and 

 tibia are somewhat longer than in the type. Skull scarcely distinguish- 

 able from that of Dermonotus fulrus, therefore much more robust than 

 in the small West Indian species of Chilonycteris. Teeth uniformly 

 smaller than those of Dermonotus fulvvs, and upper incisors separated 

 from canine by a distinct space, not as wide, however, as that between 

 the same teeth in Chilonycteris macleayi. Measurerments : Total length. 

 62; head and body, 46; tail. 16; tibia, 17; foot. 9 (8): forearm, 44; 

 thumb, 8 ; second digit, 37 ; third digit, 71 ; fourth digit, 50 ; fifth digit, 

 47; ear from meatus, 15.8 ; ear from crown, 11.4 ; width of ear, 7 ; great- 

 est length of skull, 15; basal length, 12.6; basilar length, 11.6; zygo- 

 matic breadth, 8.2; breadth of braincase above roots of zygomata. 8. —
