insects, "skims closely and somewhat leisurely over the surface of 

 the crops and grass," One that entered a room kept low down 

 near the floor, instead of flying about the ceiling as most bats do. 



Two other species of the genus, H. suillus found in the Malay 

 Archipelago, and H. aumtus from Eastern Tibet, may hereafter be 

 found within Indian limits. Both are small forms with a narrow 

 muzzle. 



Genus VESPERTILIO, L. (1766). 

 Syn. Trilatitus, Myotis, Gray. 



Muzzle long, face hairy ; the glandular prominences on each side 

 between the eye and the nostril much less developed than in Ves- 

 lieriujo, and scarcely increasing the breadth of the face ; nostrils 

 not prolonged, opening sublaterally by crescentic apertures ; crown 

 of the head but slightly raised above the face. Ears separate, 

 longer than broad, generally longer than in Vespenujo, the internal

basal lobe angular, the external margin of the ear-conch terminating 

 below the base of the tragus or very slightly in front, and not 

 carried far forward towards the angle of the mouth. Tragus long, 

 generally attenuated above and pointed. 



Tail less than the head and body (rarely equal) ; postcalcaneal 

 lobe absent or very small. 



Dentition : i. "-^, c. j^, pm. -^^, m. ^^^ The upper incisors 

 subequal, in pairs on each side close to the canines, the points of 

 the teeth in each pair generally diverging in direction, the outer 

 incisor pointing slightly outwards, the inner inwards ; lower outer 

 incisors much larger than the inner. The first and second upper 

 premolars small, the second always smaller than tlie first, often 

 minute and internal to the tooth-row. The relative proportions of 

 the three lower premolars are the same, the second being the 

 smallest, but it is rarely so minute as the corresponding tooth in 

 the u]iper jaw. The last upper molar is rather less in section than 

 half the next. 



The genus VespertiUo, as at present restricted, ranges throughout
