THE KEPTILES OF EGYPT. 
shield on each side of it broadly in contact with its fellow, with one or two small 
shields behind. Limbs and digits well developed ; 8 — 10 prominent lamellae on 
the pollex and hallux ; on the remaining digits of both extremities the lamellae 
vary from 10 to 13, the distal ones of the manus and the distal and proximal plates of 
some of the digits of the toes being occasionally undivided. Body uniformly granular, 
the granules smallest on the vertex, increasing in size on the snout, and largest on the 
sides, where there are a few generally larger than the others, and sometimes a large 
tubercle before the shoulder, and a few rounded tubercles on the sacral region; abdominal 
scales cycloid, imbricate, and larger than the lateral granules. Tail generally longer 
than the head and body, depressed, flat below, consisting of a series of verticils, each 
of which is made up of about 13, more or less, transverse series of granules, with a 
large tubercle on the upper surface, external to each side of the mesial line, and with 
another still larger at the lower angle, both of these tubercles being placed close to 
the posterior borders of the verticils ; a longitudinal line of large transverse plates on 
the under surface. 6 or 7 femoral pores (5-9 in Bengal specimens). 
In life the general colour of Suakin specimens is pale lemon-yellow with a faint 
greenish-grey tinge, the underparts being of a richer lemon and the lamellae clear 
silvery white. On the back, there are occasionally faint indications of the presence of 
dark transverse undulating bands.

The largest specimen of this species as yet on record was obtained at Pinang. The 
body and head were a fraction more than 94 millim. in length, and the tail close on 
83 millim. long : but from the accompanying table it will be seen that although there 
is not much difference between the total length of the Pinang specimen and the one
