3. EMBALIONUEA. 359 



Comparison of the above measurements sho-ws how very closely 

 A. sclinabUi agrees with F. horrens in size ; the differences are indeed 

 so slight that if the measurements of the specimens had been made 

 by the same person, it is probable they might have been almost 

 identical. This remarkably close correspondence in size and (as far 

 as I can judge from the excellent figures and description) absolute 

 agreement in dental characters, as well as in the form of the ear 

 and tragus, renders it very doubtful whether, even with the appa- 

 rently great structural differences in the form of the extremity of the 

 muzzle and of the bony palate, we should consider this species the 

 type of a genus distinct from Furia. 



Hah. Tumbez, Peru. 



Group EMBALLONUR^. 



Ears arising by their inner margins from the sides of the forehead ; 

 outer margin of the ear-conch terminating in a lobe carried for- 

 wards towards the angle of the mouth ; tragus longer than broad, 

 generally expanded above ; nostrils opening close together at the 

 extremity of the conical muzzle ; thumb and first phalanx of the 

 middle finger moderately long ; tail perforating the large interfe- 

 moral membrane about its centre and appearing upon its upper 

 surface. 



Crown of the head slightly elevated above the face-Hne ; postorbital 

 processes distinct, generally very long. 



Range. Tropical and Subtropical Eegions of both hemispheres.

(1844) (not Mag. Zool. ^ Bot. 1838, p. 99, vide infra, p. 377). 



Ears arising separately from the sides of the forehead ; outer 

 margin of the ear-eonch terminating in a long lobe behind the 

 angle of the mouth below the eye ; tragus longer than broad, gene- 

 rally slightly expanded above ; apertures of the nostrils circular or 

 oblique ; wings from the ankles or tarsi ; antebrachial membrane 

 without a pouch; interfemoral membrane large, extending much 

 beyond the point at which it is pierced by the tail, and having its 

 posterior free margin supported by long calcanea. 



Nasal bones slightly convex ; muzzle broad and flat above, in- 

 creasing in width in front of the postorbital processes. 



from the recently published original description of the species described by 

 Dr. Peters from a single specimen, which I have not yet had an opportunity of 

 examining.
