Gray here remarks, that he does not know in what respect Desmodits, 

 E,/:l<>istoma, DipJiyllia differ from tin's genus. As species of this genus, Gray has 

 particularly characterized, but with inconvenient brevity, Phyttophora megalotis 

 (tab. v, fig. 2), and nigra (tab. v, fig. 1) ; Monophyllus Leachii, Phyllostoma 

 liastatum and elongatum, Gray (tab. viii, fig. 2) ; Carollia vernicata, Gray 

 (tab. viii, fig. 3) ; Sturnira spectrum (tab. vi, fig. 1). LMacrotusWaterhowsii, 

 by him, occurs in the Ann. Nat. Hist, xiii, p. 69. 



In these Archives, p. 365, I have given the diagnoses of seven new 

 species of Phyllostoma from Brazil. 



GYMNORHINA. J. E. Gray has also given an arrange- 

 ment of the genera in his tribe Noctilionina.
