The position of the eye is not marked by wrinkles but is smooth 

 and rounded and is indicated by the line of the closed ocular 

 fissure which extends back for a distance of 2 mm. from a point 

 1-5 mm. behind the lappet at the base of the muzzle. The pig- 

 ment of the eye can be seen around this faintly appearing through 

 the continuous integument of the region. 



The position of the ear is indicated by the slight integumentary 

 depression of the external auditory meatus just behind the ocular 

 fissure and 4*5 mm. behind the lappet. 



The dorsal and ventral surfaces of the forelimbs are directed 

 forwards and backwards respectively, the preaxial and postaxial 

 borders being respectively mesial and lateral. The forelimbs are 

 separated at their bases by a much wider interval than are the 

 hind limbs, and they do not incline towards each other as do the 

 latter whose dorsal and ventral surfaces look outwards and inwards 

 respectively, the borders being actually as well as morphologically 

 pre- and postaxial. 



The free distal margins from which the digits spring in both 

 hand and foot are crescentic. 



The digits are well-marked and they all already possess claws, 

 but those of the toes are much smaller than those of the fingers. 



The natatory membrane of the manus is present as a free lappet- 

 like fold of its integument at the palmar aspect of the roots of 

 the fingers and it already reaches about as far as the nail-tips. 

 It is this fold which really forms the distal margin of the hand, 

 ventrad of the digits, seen in fig. 3. 



In the corresponding situation in the jjes there is merely a 

 slight integumentary ridge. 



The length of the free portion of the hind limb is about 7 mm. 

 and of the forelimb perhaps a trifle less. 



A trace of the calcanean spur is present in the hind limb as a 

 very minute papilla on the ventral (internal) aspect of the limb, 

 but it is hidden aw^ay in the flexure between the limb and the 

 abdomen in the ordinary position of the limb. 



The cloacal aperture is situated ventrally close to the root of 

 the tail. A small papilla is visible in the aperture. It is impos-
