the latter species is covered by 26 or 28. In other respects, 

 especially general habitus and scutellation, the two species 

 are very similar to each other. 



The length of the tail exceeds that of the trunk and head. 

 The rudimentary hind leg is small and flat, adpressed, and 

 covered with scales, so as to be not readily distinguished 

 from its surroundings. 



Rostral shield broad and low. Nostril between three 

 shields, the first labial, nasal, and internasal. The inter- 

 nasals meet behind the rostral, and form the foremost pair of 

 the shields with which the snout is covered. The internasal 

 pair is followed by two pairs of transversely narrow frontals, 

 which, again, are succeeded by a single shield thrice as wide 

 as long ; the latter may be regarded as a detached portion 

 of the vertical. Vertical five-sided, longer than broad, with 

 the lateral margins parallel. Occipitals symmetrical, narrow, 

 scarcely longer than vertical. 



Two series of small scutes between the vertical and the 

 eye, which is surrounded by a ring of very small scales. 

 Loreal and temporal regions covered with scales. Seven 

 upper labials. The mental is rather large and followed by 

 two lower labials, none of which meet those of the other side. 

 Behind the second lower labial two longitudinal series of 

 small scutes follow. 



Body surrounded by 22 longitudinal series of small scales : 

 the ventral scutes are considerably larger than the adjoining 

 scales and begin to be differentiated behind the throat ; they 

 are placed in 89 pairs. Eleven praeanal pores. Vent with a 

 pair of enlarged scutes ; smaller scutes between them and the 

 line of pores. 



Yellowish olive, with a red network all over the back and 

 sides ; the meshes of the net enclose yellow spots on the sides.
