also occur on back part of head and neck; tail rather cylin- 

 drical, with a distinct lateral denticulated fringe, the annulations 

 marked by an enlarged spinelike scale in the lateral fringe; 

 scales on upper surface of tail distinctly larger than those on 

 body, those on underside still larger; scales on belly imbricate, 

 much smaller than those under tail ; a long series of twenty-five 

 preanal and femoral pores forming a median sharp angle ; pores 

 elongate in shape; legs well developed, the adpressed hind leg 

 reaching the wrist of the adpressed foreleg; web between toes 

 and fingers very rudimentary; fourteen lamellse under longest 

 toe; toes much wider at end than at base, the basal lamellse 

 rather scalelike; inner digits on legs well developed, without 

 claws; eye nearer ear than end of snout; ear slightly nearer 

 eye than foreleg.

 marking of brown across back; lighter at base of tail; a dark

Variation. — Two other adult specimens, -both females, were 

 taken. The following variations are in evidence : One specimen 

 has fourteen and thirteen upper labials; twelve lower labials; 

 the internasal scales are reduced to one large median scale, with 

 a pair of smaller scales on each side; the angle of the mouth 

 fails distinctly to reach the posterior vertical of eye ; no preanal 

 pores, but a series of twelve enlarged scales on each side, angular 

 medially, representing the pore scales ; a series of distinct, large 

 black spots on each side of the tail just above the lateral fringe. 

 In the other specimen, the internasal scales are similar to those 

 in the type save that the second row has four instead of three 

 scales; upper labials, thirteen and fourteen; lower labials, 

 twelve; there are calcareous deposits on the sides of the neck.
