Tenasserim provinces. 



The true M. spasma inhabits Ceylon and the Malayan countries generally ; 

 and the Indian M. lyra can hardly but occur in Arakan and Pegu, as it has 

 been obtained at Amoy and in Formosa. The Bats of this genus are highly 

 predatory, and Col. McMaster records that at Eangoon one killed on suc- 

 cessive occasions two canary-birds. Nycteris javanica, Geoff., inhabits the 

 Malayan peninsula, and should be looked for in the Tenasserim provinces.

According to Captain Hutton, "this fine species commences its flight 

 rather early in the evening, and does not soar high, like the smaller 

 Bats in general, but remains below at about from twenty to thirty feet 

 from the ground, wheeling with a somewhat heavy and noiseless flight 

 around buildings and large trees in search of beetles and other insects. 

 Indeed," he adds, " I think it may be truly said of all the larger species 

 of" insect-eating "Bats, that they hawk for prey in the lower regions 

 of the atmosphere, while nearly all 'the smaller ones ascend; and the 

 reason is, that while the flies and minute insects are in the higher regions, 

 the large beetles and other large insects, of which the smaller Bats could 

 make no use, are found below among the branches of the trees. R. luctus 

 appears usually to dwell in pairs, and does not associate in communities like 

 some of the smaller species of its genus — though in a large cavern, affording 

 ample room for them to dwell apart, several pairs may sometimes be found. 

 I have taken them from the roofs of outhouses, and in wide caves in limestone 

 rocks; but they appear to fly only in the warmer months of summer,
