The sides of the body and tail may be ornamented with a varying number (in some specimens none) of distinct or irregular yellow or white ocelli, each of which may be broadly edged above and below with black. The sides of the head may be olive-brown or reddish olive (when not dark brown, as under I.), and the sutures between some or all of the shields on the top and sides of the head may be distinctly outlined in black ("Var. D, D. & B." apud Cantor.). Limbs above olive-green or brown, with or without longitudinal black lines. Tail above coloured like back, with or without black spots. Lower surfaces : chin and throat bluish white, whitish, or yellowish like the body; body bright sulphur or pale greenish yellow ; limbs sulphur or pale greenish yellow; tail yellowish anteriorly, olive-brown posteriorly. Iris reddish orange, marked with dark bronze, yellowish bronze, or " black with a golden circular ring " (Cantor). Inside of mouth purplish grey. Tongue purplish, sometimes nearly black. Size. Mabuia multifasciata grows to a larger size than the other Skinks inhabiting this region ; a male from Bangkok measures :- Total length 275 m m . (snt. to vnt. 120, tail 155) ; arm 31 mm.; leg 50 m m . This specimen has, however, a short tail; in proportion to those of smaller specimens the tail might have been 276 mm., which would give a total length of almost 400 m m. Hab.
