These figures show clearly, though the number of specimens 
examined is not very great, that while Assamese, Burmese and 
Bornean specimens agree with those from Malaya (fide 8. Flower) 
in being mostly provided with tricarinate dorsal scales, there is a 
ereater tendency among Andaman specimens for these scales to 
be quinquecarinate, as I have already suggested. !

Of this Andaman Skink the Museum possesses seven adults 
and a young one. One of the adults was obtained in the 
Botanical Gardens near Calcutta by the late Dr. Anderson ; but 
probably it had been introduced with specimens of living plants. 
As Boulenger had only Theobald’s and Stoliczka’s imperfect 
descriptions to go upon, it may be well to give a new diagnosis of 
the species, which is very distinct from any other. 
Lower eyelid scaly: a postnasal. Body stout, head large, 
triangular ; snout moderate, obtusely pointed; cheeks swollen in 
the adult ; tail long and slender, more than twice the length of 
head and body when perfect. Nostril behind suture between rostral 
and first labial; supranasals generally in contact behind rostral ; 
anterior loreal not, or but slightly, deeper than posterior, in 
contact with second, sometimes also with first, labial; frontsnasal 
slightly broader than long ; preefrontals in contact mesially ; frontal 
generally as long as frontsparietals and interparietal together, in 
contact with second supraocular ; four supraoculars, second largest ; 
superciliaris inclined to break up irregularly. Har-opening cres- 
centic, vertical, smaller than a lateral scale, without, or with 
small and indistinct, anterior lobules. Dorsal scales tricarinate, 
nuchals and laterals feebly keeled ; 24 to 26 scales round centre of 
body, subequal. The hind limb reaches the axilla. Subdigital 
lamelle smooth. Coloration: dorsal surface uniform greyish 
brown, spotted on both limbs with dark-brown and white ; ventral 
surface dirty-white or greenish, tail dull-green or dull yellow.
