the total leug'tb to the groin 4 times. The limbs when pressed to the 

 side overlap by the length of the fingers. 



There is no cauthus rostralis, and the lower jaw does not extend be- 

 yond the upper. The external nares are almost terminal, and are as 

 far apart as the distance between the inner borders of the choante. 

 The latter are rather large, and are trausverse.^ The vomeropalatine 

 series of teeth form a short transverse line, which is entirely within the 

 internal borders of the inner nares and a considerable distance poste- 

 rior to them. The tongue is wider thau long, but does not fill the wide 

 floor of the mouth laterally. A dermal groove extends posteriorly 

 from the eye to the side of the neck above the anterior border of the 

 humerus. A branch groove descends a short distance posterior to the 

 eye and turns forwards to the cauthus of the mouth. These grooves 

 divide masses of crypts, those on the inferior side of the groove being 

 most prominent. The tract above the groove resembles the parotoid 

 gland of the Ghondrotus paroticus, but is much less distinctly defined, 

 fading out upwards. 



There are eleven well-defined lateral dermal folds, and space for a 

 twelfth, which will probably be found well defined in other specimens.

part of the tail are thickly studded with crypts. There is a slightly 

 defined gular fold. 



The fore limb is as long as from its anterior base to the anterior mar- 

 gin of the eye. The toes are quite short, and their lengths, beginning 

 with the shortest, are 5-2-3-4. The posterior foot is especially robust, 

 and the sole is wider than the length of the longest finger. There are 

 no distinct tubercles on the sole. The lengths of the toes are, beginning 

 with the shortest, 1-5-2-4-3.
