40 VESPERTILIONIN.E. 



Horsfield states that this bat has the fur similar in character to Lasi- 

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

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

 and N. ornatus 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. 



Sub-fam. VESPERTILIONIN.E.

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

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.

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

 Blyth, in his Catalogue, places it separately from other species of Ves- 

 pertilio, 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 emar- 

 ginatus, 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.
