There is no eantliiis lustralis, ami the lower jaw does not extend be- 

 yond the upiKT. The external iiares are almost terminal, and are as 

 far apart as the distance b.'twcLMi the inner bordiM'S of the choana'. 

 The latter are rather lar^e, and are transverse. The vonieropalatino 

 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 ton,-;ae is wider than Ion;;-, bnt docs not till the wide 

 floor of the mouth laterally. A dermal yroove extends posteriorly 

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

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

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

 divide masses of crypts, those on the inferior side of the {groove hi'.\u<r 

 most prominent. The tract above the groove resembles the parotoid 

 ftland of the Vliondrotm parotiviin, bnt is much less distinctly <lelined, 

 fading out upwards. 



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

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

 defined gidar 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 tiieir lengths, beginning 

 with the shortest, are .5-li-.")-t. Tiie posterior foot is (vspecsially robust,

 im distinct tubercles on the sole. The lengths of the toes are, In^ginning
