Ears intermediate in size between those of typical examples of 

 Ph. bicolor and Ph. fulva, the outer margin of the ear-conch flattened 

 in the upper third, as in Ph. hicolor. 



Fur, above, very dark brown, almost black on the surface, the 

 basal three fourths of the hairs pale greyish ; beneath, greyish 

 brown, slightly darker towards the extremities of the hairs.

Ears shorter than the head, smaller than in any of the previously 

 described forms ; the frontal sac appears to be quite absent in the 

 female ; the interfemoral membrane is also less triangular behind, 

 and the extremity of the tail projects more. However, the three 

 specimens of this form agree so closely in aU other respects with 

 Ph. bicolor, that it is impossible to consider them as representatives 

 of a distinct species (Plate IX. fig. 11). 



(For measurements see Table below.) 



Hab. Amboina ; peninsula of India. 



In the following Table the measurements of Ph. bicolor and its 

 varieties are compared. It may be seen that a regular gradation 

 exists in the size of the ears from Ph. amboinensis to Ph. fulva.
