V.—Description of a new Lizard from the Gaboon. 
By G. A. Boutencer, F.R.S. 
Mabuia benitensis. 
Snout moderate, pointed. Lower eyelid with an undivided 
semitransparent disk. Nostril behind the vertical of the 
suture between the rostral and the first labial ; a postnasal ; 
anterior loreal in contact with the first labial; supranasals in 
contact behind the rostral ; frontonasal broader than long, in 
contact with the frontal; latter as long as the frontoparietals 
and interparietal together, in contact with the second and 
third supraoculars ; four supraoculars, second largest; six or 
seven supraciliaries ; parietals just meeting behind the inter- 
parietal; a pair of nuchals; subocular between the third and 
fourth or fourth and fifth upper labials, about twice as long as 
these shields, not narrowed inferiorly. Har-opening oval, 
smaller than the eye-opening, with three or four very minute 
lobules on its anterior border. Dorsal and lateral scales 
quinquecarinate, the outer keels short ; nuchals sex-, septem-, 
or novemcarinate ; 28 or 30 scales round the middle of the 
body, subequal. The hind limb reaches the wrist or the 
elbow of the adpressed fore limb. Subdigital lamella smooth. 
Tail not twice as long as head and body. Greyish brown 
above, with longitudinal series of blackish spots ; a blackish- 
brown white-edged lateral band extending from the end of 
the snout to the base of the fore limb; the lower white streak 
is broader than the upper, borders the upper lip, and is itself 
black-edged from below the ear; limbs with small whitish 
spots; lower parts unitorm whitish.

Two specimens from the Benito River, French Congo, 
collected by Mr. G. L. Bates. 
Very closely allied to M. maculilabris, Gray.  Distin- 
guished by the more pointed snout, the greater number of 
supraciliary shields, and the shorter outer keel on the dorsal 
scales.
