REPTILES. 
Iguana fasciata. 
First described by M. Brongniart, {Bull. Soc. Pliilom. II. No. xxxvi. t. 6 f. I.) as having 
been collected by Riche. It has been said since to come from Java, but it proves to be a common 
American species. Kuhl (and Daudin ?) referred it to the genus Agama. Cuvier has formed of it 
a genus, under the name of Brachylophus, placing the genus among the Agama ; but it has the 
palatine teeth, and all the characters of the true Iguana. 
Cyclura acanthura. Gray in Griff. Anim. Kingd. 
Lac. acantliura. Shaw, Zool. 
Olive, black dotted and marbled with several black bands across the back, containing one or 
two oblong pale spots on the sides. 
The end of the tail, which in this specimen had been re-produced, armless, covered with nearly 
uniform oval, keeled, rather small scales, somewhat like the scales between the rings of armed ones, 
but rather larger, more oblong, and more keeled. 
Opiiyessa BILINEATA. 
Olive black, with a broad transverse dark brown band, interrupted with a pale streak, down each 
side of the back ; side of the head with three black streaks, diverging from the back of the orbit, the 
two upper arising from the back angle of the lid, and the third tending to the middle of the tympanum ; 
chin, and beneath, greyish white ; sides of chin and body, brown, dotted. Limbs and tail banded, 
bands of the tail becoming broader tow'ards the lip. Scales of the back small, squarish, convex; of the 
outside of the limbs, larger, keeled ; of the tail, broader, keeled, and thin ; of the head, small, irregular, 
convex. Tail twice as long as the body and head ; toes very long, and very unequal.

Genus CHAMiELEOPSIS. 
Wiegmann s MSS. — Gray in Griffith, Anim. Kingd. 
lleadlyrate; forehead dilated, expanded over the eye; occiput compressed, produced, covered 
with small scales like the back. Tympanum exposed, nearly superficial. Teeth small, on the 
inner edge of the jaws, crown rather compressed, three-lobed ; palatine teeth distinct, subulate, 
in a single row. Nostrils small, round, pierced in the centre of a rather larger scale, placed on the 
side of the head, rather nearer the tip of the muzzle than the angle of the eye. Throat slightly 
dilated, covered with longitudinal rows of large keeled scales. Body compressed, covered with 
small scales. Back, with a slight denticulated crest of rather larger scales. Ribs apparently 
encircling the body. Limbs long, slender. Toes, five, five, long unequal, especially the hinder ones. 
Claws five, five, sharp, incurved. Femoral or subanal pores, none. Tail long, slender, tapering. 
This genus has much of the external appearance of the chameleons ; but its toes are regular and 
free, and its teelli, like those of all the Saurians of the New World, are placed on the inner edge of 
the jaw. It has a considerable affinity to the basilisk in habit, but differs in the form of its head, 
and in the tail being round.

Pale brown, (under the epidermis, whitish) varied with irregular brown spots and bands. Tail 
brown, with distant whitisli bands. The edge of the lips brown spotted, with a band across the fore-
