NYCTINOMUS. 355 



lobe by a deep notch. The thickened horizontal basal lobe 

 commences some distance inside the inner margin, and extends 

 nearly across the ear-conch inside, covering the eye. Tragus very 

 small, subtriangular, truncated above. Muzzle broad, lips very 

 thick, the upper overhanging the lower, both wrinkled, but the 

 upper more so. 



"Wings from tibia, the point of junction varying. Calcaneum 

 short, scarcely extending half the distance from the ankle to the 

 tail. The free portion of the tail longer than that contained in the 

 membrane. Distribution of the fur as in N. tragatiis. 



Lower incisors 4, first upper premolar small. 



Colour of fur brownish black to greyish brown above, sometimes 

 the same but generally paler below, basal portion of the hair lighter 

 in colour. 



Dimensions of an adult male : head and body 2'7 inches, tail 

 1-55, forearm 1-95, tibia 0-65, ear from crown O5. 



Distribution. Generally distributed throughout India, Burma, and 

 the Malay countries, but not recorded from Ceylon or the 

 Himalayas. 



Habits. This bat is found during the day in caves, deserted 

 masonry buildings, &c. Tickell met with it in countless myriads 

 inhabiting limestone caves at Phagat, 30 miles from Moulmain. It 

 has, like others of the genus, a steady powerful flight high in the 

 air, effected by sweeps of its long narrow wings. An allied species, 

 N. cestoni^ has the power of sinking its eye in the socket and 

 thrusting it out again. 



Two other species of Nyctinomus, N. mops and N. johorensis, are 

 found in the Malay Peninsula and islands, as is also Chiromeleg 

 torquatus, already mentioned.
