TIlis fine species i.s of mtlier robust proportions. Tiio hoail is wiiU' 

 iiiid distinct from the neck, tlirough tiie protuberance of a postcrini' 

 superior angle on eacli side. It is also perfectly tlat and smooth above, 

 e.\ce|)ting a f>entle slope from a line connecting the orbits ' ) the end 

 of the muzzle. The body is .slightly compressed, atid its length from 

 a.xilhi to groin is just equal to the length from the axilla to the end of 

 th(^ muzzle. The tail is long, exceeding the length of the head and 

 body by the depth of the latter. It is very much compressed, and has 

 a wide dermal border both on the inferior and the superior edges. 



Viewed from abo> e, the head is contracted t(twar<ls tlie muzzle with 

 curved lateral outlines, and the end of the muzzle is truncate. It al.so 

 juojects considerably beyond the lower Jaw. The iu)strils appear to be 

 terminal, but directed laterally, and tiie spacte between them equals 

 two thirds that between the bases of the eyelids, and exceeds by one- 

 qmu ter the space between the internal nares. It also equals the h'ligth 

 from tlioeye to the nostril, and exceeds by a very little the length of 

 the eye-lissure. 



The upper lip begins to descend posteriorly at a point halfway be- 

 tween the nostril and the e.\e, and does not ri".e again, but conceals the 

 lower Jaw. Tlui rictus is Just behind the jiosterior angle of the eye. 

 Anterior to this point it is Joined on its internal side by a short lamina, 

 which represents the lower lip of the perennil)ranchiate species of 

 lialrachia. This lip is entire) concealed, and there is iu) fold in front 

 of it, on the lower Jaw. 



The tongue is oval, and very small. It is only free at the sides, and 

 that but slightly. The vomeropalatine teeth are in two straight series, 

 which converge forwards and Join directly between the choana'. 



The limbs are robust, the posteriiu- ones the nu)reso. Applied to the 

 side, tiiey overlap by the lengtli of the postericu' foot with tarsus. The 

 digits ditfer much Irom each other in length, but not so much so as in 

 the 1>. riridcsccus. The second (first) finger is very short, and the fifth 

 is a little longer, while the third and fourth are of usual length, the 

 third the shorter. 1 iie phalanges are l-L'-;{-'-'. The toes are arranged 

 iniicli as the tlnger.s, the hmger ones of m.'dinm length, and the lirst
