groove passing down from the nostril; and in the intervening 

 space between and below the nostrils is prominent and rounded. 

 Ears confined at the bases of their inner margins, which meet on 

 the forehead slightly in front of the eyes ; the outer margin is 

 also carried forward in front of the eyes, terminating on the face 

 above the upper lip, so that the eye is contained within the 

 external ear; tragus triangular above and attenuated towards the 

 tip. Feet slender with long toes. Tail nearly as long or longer 

 than the body. Skull considerably vaulted behind the short 

 muzzle.

Species: — barbastellus, Schreber. Described b.y Bell, who, 

 however, has created some confusion by describing it (p. 81) as 

 Barbastellus daubentonii, this specific name belonging to a ver}' 

 different species, Vespertilio daubentonii (oj). cit., p. 60). 



EHINOLOPHID^. 

 The bats belonging to this family are readily distinguishable 

 by the curious form of their foliaceous nasal appendages, and by 

 their rudimentary premaxillary bones supporting two minute, 

 usually bilobed incisors ; their molars are acutely tubercular, and 

 enable them to crush with ease the hard cases of coleopterous 

 insects which (from remains found in their stomachs) appear to 

 constitute a large proportion of their food. Their eyes are 

 minute, and often with difficulty discovered in spirit specimens ; 

 the eye -ball is extremely small, and the optic nerve reduced to 

 the thickness of a very fine thread, contrasting remarkably with 

 the development of the auditory and olfactory nerves in the same 

 animals.

Nose-leaf very complicated, consisting of three distinct poi'- 

 tions — anterior, central, and posterior ; tlie anterior horizontal 

 portion is horse-shoe-shaped, usually angularly emarginate in 

 front, containing within its circumference the nasal orifices and 

 the central erect nasal process ; the posterior nose-leaf is 

 triangular, erect, with cells on its anterior surface ; the central 

 process rises between and beliind the nasal orifices, is flattened
