Or 
(3) Hemidactylus oxyrhinus. 
Snout pointed, slightly longer than the distance between the eye and the 
ear-opening, which equals the diameter of the orbit ; forehead slightly con- 
cave ; ear-opening small, oval, oblique. Body and limbs moderate. Digits 
. moderately dilated, free ; 7 or 8 lamellae under the thumb, 8 or 9 under the 
fourth finger, 6 or 7 under the hallux, 11 or 12 under the fourth toe. Head 
covered with small convex granules increasing in size posteriorly ; rostral 
subquadrangular, not twice as broad as deep, with median cleft above ; 
nostril pierced between the rostral, the first upper labial, and three small 
scales; 8 to 10 upper and 7 or 8 lower labials ; symphysial large, triangular, 
more than twice as long as the adjacent labials; four chin-shields, median 
pair largest and in contact behind the symphysial. Back covered with equal 
or sub-equal, rather large, obtusely keeled, juxtaposed tubercles ; ventral 
scales much smaller, cycloid, smooth, sub-imbricate. Male with two preanal 
pores. ‘Tail cylindrical, tapering, covered with uniform small smooth scales, 
with a median series of transversely enlarged plates inferiorly. Pale buff or 
greyish brown, with more or less distinct darker markings in the form of four 
wavy cross-bars on the nape and back, and annuli on the tail; the caudal 
annuli black in the young, separated by white interspaces ; a dark streak on 
each side of the head, passing through the eye.

The largest specimen, with reproduced tail, measures 50 millim. from 
snout to vent. Several specimens from Abd-el-Kuri. 
(4) Hemidactylus forbesii. 
Closely allied to H. flaviviridis, Riipp. (coctwi, D. & B.). Snout obtusely 
pointed, longer than the distance between the eye and the ear-opening, once 
and one-third the diameter of the orbit; forehead concave; ear-opening 
large, oval, oblique. Body and limbs moderate. Digits moderately dilated, 
less than in H. flaviviridis, free; 11 or 12 lamelle under the thumb, 11 or 12 
under the fourth finger, 10 or 11 under the hallux, 14 or 15 under the fourth 
toe. Head covered with uniform granules, largest on the sides of the snout ; 
rostral not twice as broad as deep, notched and cleft above ; nostril pierced 
between the rostral and three small scales; first upper labial sometimes 
entering the nostril; 10 or 11 upper and 8 or 9 lower labials ; symphysial 
large, triangular, at least twice as long as the adjacent labials ; a pair of large 
chin-shields, forming a suture behind the symphysial, usually flanked by a 
pair of much smaller shields. Back covered with minute granular scales, 
among which slightly enlarged round tubercles may be irregularly scattered ; 
_ ventral scales slightly larger, much smaller than in H. flaviviridis, juxtaposed 
or sub-imbricate. No preeanal or femoral pores. Tail moderately depressed, 
tapering toa fine point, covered with very fine small smooth scales, and a few 
scattered pointed tubercles on its basal part; no regular series of trans- 
versely enlarged lamellar plates on the lower surface. Pale greyish above, 
with rather indistinct brown spots and marblings on the head and body, and 
cross-bars on the tail ; white beneath.
