REVIEW OF THE BAT GENUS HEMIDERMA—HAHN. 107 



Mr. Geriit S. MilltT, jr., rocontl}^ reexamined the specimen und 

 made the following- notes: ''Adult skin, with the skull removed but 

 not cleaned. Color rather dark, in no wa}" characteristic. Forearm, 

 38.5 nmi. ; third finger, 82; foot, 11.8; tibia, 16; upper tooth row, 

 7.4.'' The small size here given would seem to indicate that the speci- 

 men may actually be a representative of a small South American form 

 allied to suhrufum, but in the absence of more definite data in regard 

 to locality and skull characters it seems ])est to regard the name, at 

 present, as a synonym of 'perspiclUatiDfi. 



Mcolor {Phyllostoni(i) Wagner, Schreber's Saugeth., Suppl., I, 1844, 

 p. 400. Wagner here renames the YampyruH mriclriui< of Spix (ante- 

 dated by PJnjUostonia sorichi^m, Geoffroy;) His description does not 

 show any characters by which the species can be distinguished from 

 P. hrevicauduni Wied which is described on the next page. The type 

 was from Brazil and the name is a s3monym iov per-spiGlllatutii 



azteca {CaroUid) Saussure, Rev. et Mag. ZooL, 2me. ser., XII, 1860, 

 p. 480, pi. XX, figs. 1, la. Saussure described this form from "Tropi- 

 ical and Temperate Mexico," giving as the piincipal character a 

 lanceolate and pointed antitragus. After examining specimens of the 

 genus from Mexico I cannot regard this character as having any value. 

 The figure which Saussure gi\'es of the tragus appears to have been 

 drawn from memory some time after the specimens were last examined, 

 while the figure of the feet resembles those of a Glossophaga. His 

 measurements, however, serve to identify the species as the largest 

 form of the genus known from Mexico. Peters, Dobson, and others 

 have considered this to be identical with the South American species. 

 Sufficient material is now at hand to show conclusively that it is a 

 well-marked form, nmch larger than the South American bat, though 

 connected with it by intermediate forms in Central America, Azteca 

 therefore stands as the valid name for a form which is here recognized 

 as a sub-species of perspicillatum. 



minor {Rhinopfi) Gray, Proc. Zool. Soc, 1866, p. 115. No specific 

 characters were given by Gray, but a new genus (Phmops) was estab- 

 lished and the type of the genus was given as '^'' P/miops minor sp. 

 nov." Mr. Miller has recenth^ reexamined the type for me and 

 made the following notes upon it: "Type (49. 10. 15. 13.). [British 

 Museum of Natural History.] Very young, milk incisors in place 

 and permanent cheek-teeth not fully grown. Forearm, 35.5 mm. ; foot, 

 11.7; tibia, 14.2. Color rather dark, in no way characteristic." The 

 specimen was from Brazil and the name is a s^'nonym of perspi- 

 cillatuni.

 has been generally recognized by mammalogists. The species has
