far as the tip of the snout. The vomerine teeth do not usually (if ever in 
adults) commence from the inner hinder edge of the choanae, being very 
distinctly and in some cases very widely separated therefrom. The colour 
and markings are given to much variation. The loreal region is not 
strictly vertical, being oblique and concave. The belly may be entirely 
smooth or it may bear glandular granulations : or, as in a few specimens, 
the whole of the ventral surface excepting the throat may be granular. 
Localities : Ambatoharanana, Analamazotra, Ambilo, and Folohy.

R. AGLAVEI, sp. nov. (PI. IX). A single specimen, measuring 43 mm. 
from snout to vent, from the forests adjacent to Analamazotra. 
Description. — Head depressed, snout rounded, head about as broad as 
long. Loreal region concave : canthus rostralis not sharply defined and 
curved inwardly : nostril on a raised prominence, nearer the tip of the 
snout than the eye. Interorbital space about as long as the distance which 
separates the nostril from the orbit. Tympanum distinct, its diameter 
slightly less than half that of the eye. Vomerine teeth in slightly curved 
groups of moderate size, the exposed portion of the vomers reaching very 
slightly in advance of the hinder level of the nares. Tongue of moderate 
size, with a pair of distinct pits of rather large size, which are distant from 
its anterior attachment about two-thirds of its total length. 
Fingers, webbed at the base, the web extending as a light fringe all 
along the digits and developed as a slightly denticulated fringe on the 
outer digits : first finger considerably shorter than second : fourth finger 
extending further than the second. 
Toes, between one-half and two-thirds webbed. 
Tips of digits dilated into subtriangular discs, those of the fingers 
large and in breadth considerably greater than the diameter of the 
tympanum, except in the case of the disc of the first finger which is only 
slightly smaller than the tympanum. 
A rather small inner metatarsal tubercle, elliptic, and slightly 
prominent; no outer metatarsal tubercle. Subarticular tubercles of digits 
very prominent, especially those of the fingers. The palms of the hands 
and the soles of the feet are closely granulated. 
The tibio-tarsal joint of the adpressed hind limb reaches about as far 
as the nostril: 
Skin : dorsal surface strongly and unevenly corrugated on the head, 
but somewhat smoother on the back and on the limbs : lower surface of 
body rather finely granulated throughout, that of femora rather more 
coarsely so. 
A denticulated cutaneous fold borders the anterior limb from the 
outer finger as far as the elbow and the posterior limb from the outer toe 
to the ankle : four distinct cutaneous denticulations in a transverse line at 
the posterior end of the body just below the vent : an unbroken continuous 
fold on the flanks. 
Colour : in life, mottled darker and lighter green, the general colour 
very effectively serving to conceal the animal amongst the lichen and 
moss which in this locality cover the bark of the forest trees : in its habits 
it resembles Uroplates fimbriatus , Schneid. which was also found in 
precisely the same locality. The present colour of this specimen, after 
having first been preserved in formalin and then transferred into spirit, 
is as follows : upper surface of head and body blue-black : limbs cross- 
barred, about four conspicuous transverse blotches on the thighs : hands 
and feet also cross-barred. Lower surfaces entirely pale, minutely speckled 
with dark brown.
