Ph. standingi, sp. nov. Closely related to Ph. mutabile and to a 
less extent to Ph. laticauda. 
The chief characters of importance are : the small size of the naso- 
rostrals and their separation by two scales ; the proportional lengths of 
the snout to the diameter of the orbit and to the distance from the orbit 
to the ear ; the size and number of the chin-shields ; the lepidosis of the 
body ; the shape, scaling, and segmentation of the tail. 
Description. — Snout nearly twice as long as the horizontal diameter 
of the eye, and about one and a half times the distance from the eye to 
the ear opening ; the actual measurements are : — 
Snout 11 mm. : horizontal diameter of eye 5 -6 mm. : distance of eye 
to ear opening 7 mm. 
Rostral with median cleft above. Nostril pierced between first upper 
labial, naso-rostral, postnasal, and a small scale between the last two 
scales ; naso-rostrals small, separated by two small scales. Nine upper 
and seven lower labials. Mental sub-pentagonal ; four pairs of chin- 
shields bordering the labials ; inner pair the largest. Scales of body 
smooth ; those on the flanks about the same size as the dorsals. Tail 
oval in section, not as broad as the back. Tail-segments composed of six 
or seven whorls of scales above ; lower surface somewhat irregularly scutel- 
lated, though medianallv a double row of enlarged scales can be easily 
discerned. 
Colour above emerald green with numerous dark irregular transverse 
bars ; below white, the throat slightly flecked with bluish-grey, and tail 
bluish. 
Measurements : from snout to vent, 87 -5 mm. ; tail (imperfect), 
61 4 mm. 4251. 
We have much pleasure in naming this species after Dr. H. F. Standing 
of Tananarive. 
Ph. laticauda, Bottg. Our specimens show thejollowing characters, 
which seem to be worthy of mention. The number of femoral pores varies 
from 20 to 22. The naso-rostrals are usually single, but in one specimen 
two on each side are present. The rostral may or may not have a cleft 
above. 
Localities : One specimen from Mojunga, the others from Maroa- 
malona. 4056, 4059, 4065, 4067, 4069, 4070, 4074. 
Ph. madagascariense, Gray. Some specimens from Ambilo in 
which we notice that the median dorsal cleft of the rostral scute may or 
may not be present. 4077-81. 
Ph. lineatum, Gray. Many specimens from the eastern parts. In 
one example, a juvenile, the mental scute is in contact with three chin- 
shields, instead of with two as in typical specimens. 4082-4106. 
Uroplates fimbriatus, Schneider (Plate VIII). Several specimens 
from the forests adjacent to Analamazotra and from other parts in the 
east of the island. 4107-16. 
U. ebenaui, Bottg. (Plate IX). A single specimen from Analamozotra, 
answering to the description and figure of U. phanlasticus, Blgr., which 
has been reduced by Mocquard to a synonym of ebenaui. 4252.
