Subfara. II. PHYLLOSTOMINiE. 



The four groups into which this subfamily has been divided 

 (vide p. 447) corresponds to Prof. Peters's subfamilies of the same 

 names. So closely, however, for the most part, are the genera of 

 each group allied to one another, that it may be considered doubtful 

 whether these groups should not rather be called genera, and the so- 

 called genera subgenera. This is especially noticeable in the first 

 group, the Vampyri, which includes such apparently widely different 

 forms as Vumpyrus spectrum and Phyllostoma hastaium, yet between 

 which so many perfectly intermediate species come that it is neces- 

 sary either to unite all in one genus or place the intermediate 

 species in intermediate genera. The latter course has been adopted 

 as more convenient, leading to less change in nomenclature, and 

 facilitating the discrimination of the species. 



Group 1. VAMPYEI. 



Muzzle long, and narrow in front ; the distance between the eyes
