40 TESPEKTILIONINJE. 



Horsfield states that this hat has the far similar in character to Lasiu- 

 rus Pearsoni, being delicate, soft, and silky ; and I see that in the last 

 edition of the Catalognie of Hodgson's specimens, it is classed as a Lasiurus 

 and N. omatus is considered to be the male. It is also stated to have 

 some affinity to Vesp. formosa, Hodgson. This bat is stated to have 

 been procured from near the snows in Sikim. If this be the case, its 

 habitat is very different from that of ornatus, which frequents warm 

 valleys ; and as there are various other differences in the descriptions, 

 without further evidence I shall keep them distinct. 



Sab-fam. Vespertilionin^. 



4 • 

 Lower molars usually six on each side ; incisors - ' tragus, long thin 



6 



and narrow, more or less pointed. These bats are difficult to group in 

 genera, and almost require a special cheiropterologist. Mr. Tomes, indeed, 

 has undertaken the task partially, and it is to be hoped he will publish 

 a complete history of Cheiroptera. Several groups have been generally 

 recognized. 



Gen. Lasiurus, Horsfield. 



Char. — Head small ; ears oval, short, pointed ; tragus short, bent for-

wards; molars or - — -; with a minute premolar close to the 



5 — 5 6 — 6 

 canines above ; interformal membrane hairy above ; wings hairy along the 



forearm. 



This group is classed as a section only of Vespertilio by Tomes, but Blyth, 



in his Catalogue, places it separately from other species of Vespertilio, 



though classing it as a typical Vespertilio apud Tomes, which I do not 



think that naturalist intended ; and as the bats referred " to, or near to 



this group," by him, viz., suillus, Pearsoni, formosus, and emarginatus, 



are certainly of a different type from various other species of Vespertilio. 



I shall class them here under the three sub-generic groups of Lasiurus, 



Murina, and Kerivoula.
