nearly obscured by very fine brown punctulations, which do not usually extend on to
the granules of the belly, which are yellowish.

This is not an uncommon species at Shuay-goó-myo, Upper Burma, where
I obtained it in the month of March under logs of timber near the river bank.
These specimens from Upper Burma agree in all their details with individuals
from Siam ; and, like all the examples of S . erythrcea that have come under my
observation, they have no tubercle at the base of the fourth toe. I t was the existence
of this tubercle, and the very prominent character of .the tubercle at the base of
the first toe of S . tytleri, Theobald, that led Stoliczka to consider the Lower Bengal
form as distinct from H. erythrcea. In all other respects, however, the two forms
are so closely allied that it seems extremely doubtful that they are distinct ; but as
the materials are not yet sufficient to settle the question, I have hesitated to include
H. tytleri as a synonym of S . erythrcea.

Body slender. Head of moderate breadth and rather flat, but slightly arched
from behind forwards and of little vertical depth. The breadth across the tympana
equals the distance between the hinder border of one tympanum and the tip of the
snout. The transverse interval between the nostrils is four-fifths of that between the
tympana. The canthus rostralis is rounded, with the loreal region deeply concave,
with the nostril thus close to the end of the snout. The tympanum is large,
nearly equalling the size of the eye. The vomerine teeth are very feebly developed
on two obscure ridges directed obliquely backwards from the anterior inner angle of
the choanse, but widely separated from eaeh other in the mesial line. The tongue is
elongately circular and broadly notched behind. The limbs are long and slender ;
the fore limb from the head of the humerus to the tip of the third finger equals
the distance between the vent and the front border of the tympanum. The
length of the body from the vent to the snout almost equals the distance between
the vent and the heel. The rudiment of a web occurs at the base of the fingers.
The toes are not broadly webbed, but the membrane, although emarginate, reaches
to the disks in all the toes with the exception of the fourth, where it ceases
at the distal end of the second phalanx. A small elongated tubercle at the base of
the first toe. Disks of the fingers very feebly developed, but those of the toes more
strongly so, but not prominent, both fingers and toes being very slender. The first
finger slightly exceeds the length of the second, but is slightly shorter than the fourth,
considerably shorter than the third. The fifth toe is very slightly longer than the
third, while the fourth is one-third of its length longer than the fifth.

A narrow glandular fold from behind the eye along the side of the body.
Skin perfectly smooth. ■
The colour of all the upper parts is dark olive-brown, with a dark, almost
blackish band from the snout through thé eye, along the sides to the groin, and a
narrow pale-yellowish line from below the eye to the shoulder. A narrow, obscure
greenish-yellow line along the glandular fold. The fore and hind limbs obscurely
banded with brown, but on the hind limbs the colour is much better defined,
dark-brown bands with pale margins occurring at regular intervals. The throat and
chest are almost black from the profuse fine punctulation of the skin with a dark-
brown pigment which is more sparsely distributed on the under surface of the
limbs and on. the belly, the latter being yellowish. The membrane of the fingers is
similarly punctulated.
This species was found under stones in a hill stream debouching into the
Irawady, in the second defile.
I have associated the name of the lamented Margary with this species. He
took a lively interest in the scientific objects of the Expedition of 1875, but was
ruthlessly murdered by the Chinese at Manwyne.

These specimens agree in all their details with the types with which they have
been compared.
In the month of July I found a few bushes about Momien covered with this frog.
