BULLETIN OF THE 



cartilaginous flaps, covered with a thick leathery naked membrane, which 

 is deeply indented opposite the intervals between the toes, and serves to 

 connect the rather diverging digits. The three middle toes are provided 

 with long, well-developed nails ; the outer toes are without true nails, but 

 in place of them are thickened, horny disks, which may be regarded as 

 rudimentary nails, which an examination of the skeleton shows them to 

 be. The outer toes are slightly shorter than the three middle ones, which 

 are sub-equal. 



Fore Limbs. — The fore feet (Fig. 6, PI. I, fa nat. size) are large, tri- 

 angular, and situated but a little in front of the middle of the body. 

 They terminate in a thick, hard, membranous flap, which is slightly and 

 somewhat irregularly indented on the inner side. The terminations of the 

 digits are indicated by small circular horny disks or rudimentary nails. 



Measurements. — The following table of external measurements of two 

 males, one very aged and the other mature, indicates the general propor- 

 tions of the body. A part were taken from the moist skins before stuffing, 

 and the others from the same skins mounted.
