eye. Both iii)per and lower pali»ebiie are transparent, a feature pecu. 

 liar to til is species. 



Tlie pores of tiie skin are large and on all the upper surfaces closely 

 placod ; on the sides more distantly. The mucous p(U'es on the head are 

 distinct and larjie. They form a douhle seri«is along the canthus ros- 

 tralis, ami a snigle one ahove the orhir, which turns round the latter be- 

 hind, and is conf'inued b'dow it and along the side of the muzzle to the 

 nostril. A series of similar large i)ores extends along the middle of each 

 side, one a little in front of the median point of the intercostal spaces. 

 Tiie tail is compressed fnun the base, and not elevated ; it carries a strong 

 free dermal border along the median line aboveon the distal two thirds; 

 a narrower dermal margin exists on the inferior distal half. The limbs 

 are short and weak, but the digits are well developed. The posterior 

 extended forwards measures If) intercostal intervals; the anterior 

 measures backwards 4i of the same, counting the axillar. The jdia- 

 langes nuMd)er on the posterior feet \-2-',i-',i-2; on the anterior, 1-2-3-2; 

 the terminals are (piite acuminate, especially behind, where in one indi- 

 vidual they have a slightly corneous sheath. Tiiere are 17 costal folds 

 and an axillar space. The tail is not annulate. 



The rictus of the mouth measures nearly the diameter of the eye 

 behind it. The tongue issmall and free all round, cxceptat the anterior 

 margin and along the median line to the glossohyal pedicel. The 

 vomeiine teeth exteiul behind the nares in two series, which are con- 

 vex posteriorly; they approach each other as though at an angle 

 directed anteriorly, and then suddenly curve backwards and form the 

 pterygoid series. These are more slender and more nearly approxi- 

 mated than in any other species, and consist ea(!h of but one row of 

 teeih to th(^ point where they begin to diverge; /. c, near the posterior 

 |)art of th(^ globe of the eye. They do not diverge widely and exhibit 

 but a few scries of teeth.

The color is a deli(Mte yellowish-brown, with numerous brown lines 

 interspersed, which form several dark bands along the side. A nar- 

 row dark line extends from the orbit to near the axilla. A narrow 

 yellow line, brown-bonlered above and below, extends from axilla to 

 groin. The tail, belly, and gnlar region are closely brown-8i)ecked; 

 similar specks occur on the sides of the hea<l behind. The ground color 

 of the belly is yellow.
