458 G. E. Dobson — On a new Genus of Rhinolophidce, &c. [No. 4, 



from the middle of the humerus to the middle of the femur, but 

 the humerus and femur are completely naked beyond the body ; 

 the distribution of fur on the under surface of the interfemoral 

 membrane is similar to that above.

The anterior upper premolar is minute with a flattened crown, 

 and is placed outside the line of teeth ; the upper and lower in- 

 cisors are bilobed ; the upper canines have large cusps at their 

 bases posteriorly.

The characters of the nasal appendages would be sufficient, ac- 

 cording to Dr. J. E. Gray's system of classifying the genera of 

 Bhtnolophida* to require the formation of a new group for the 

 reception of the genus, based on this species, which would thus 

 take its position next the Rhinolophina : — 



I. Rhinolophina. 



II. Trianopina. 



III. Phyllorhinina. 



IV. Rhinopomina. 



V. Nycterina. 



The characters of the group are those of the genus as given in 

 the commencement of this paper, and in the absence of o«her genera 

 must necessarily remain so without modification.
