five inches in
length, it is one line and a half.

[Illustration: CERATOPHORA TENNENTII and C. STODDARTII]

Among the specimens sent from Ceylon by Dr. Kelaart, and now in the
British Museum, there is one which so remarkably differs from _C.
Stoddartii_, that it attracted my attention, by the peculiar form of
this rostral appendage. Dr. Guenther pronounced it to be a new species;
and Dr. Gray concurring in this opinion, they have done me the honour to
call it _Ceratophora Tennentii_. Its "horn" somewhat resembles the comb
of a cock not only in its internal structure, but also in its external
appearance; it is nearly six lines long by two broad, slightly
compressed, soft, flexile, and extensible, and covered with a
corrugated, granular skin. It bears no resemblance to the depressed
rostral hump of _Lyriocephalus_, and the differences of the new species
from the latter lizard may be easily seen from the annexed drawing and
the notes given below.[1]

[Footnote 1: The specimen in the British Museum is apparently an adult
male, ten inches long, and is, with regard to the distribution of the
scales and the form of the head very similar to _C. Stoddartii_. The
posterior angles of the orbit are not projecting, but there is a small
tubercle behind them; and a pair of somewhat larger tubercles on the
neck. The gular sac is absent. There are five longitudinal quadrangular,
imbricate scales on each side of the throat; and the sides of the body
present a nearly horizontal series of similar scales. The scales on the
median line of the back scarcely form a crest; it is, however distinct
on the nape of the neck. The scales on the belly, on the extremities,
and on the tail are slightly keeled. Tail nearly round. This species is
more uniformly coloured than _C. Stoddartii_; it is greenish, darker on
the sides.]

_Geckoes_.--The most familiar and attractive of the lizard class are the
_Geckoes_[1], that frequent the sitting-rooms, and being furnished with
pads to each toe, they are enabled to ascend perpendicular walls and
adhere to glass and ceilings. Being nocturnal in their habits, the pupil
of the eye, instead of being circular as in the diurnal species, is
linear and vertical like that of the cat. As soon as evening arrives,
the geckoes are to be seen in every house in keen and crafty pursuit of
their prey; emerging from the chinks and recesses where they conceal
themselves during the day, to search for insects that then retire
