the specimens is an adult male, 25 inches long, the smaller half-grown, 
13 inches long. The coloration and the dentition are as follows :— 
The ground-colour of the broad back is brown or olive-brown, 
bordered on each side by a black line, which becomes indistinct 
posteriorly, and is more conspicuous in the young specimen ; those 
black lines are separated from each other by five or six series of 
scales, and show button-like swellings in regular interspaces ; black 
transverse lines run obliquely from one line to the other, most con- 
spicuous on the anterior part of the trunk, whilst they appear in 
the form of specks towards the middle of the length, entirely dis- 
appearing posteriorly. A blackish-brown band proceeds from the 
tentacle through the upper half of the eye along the side of the body 
to the end of the tail; it occupies two to three series of scales, and 
is separated from another similar band, running along the lower part 
of the side, by a brownish-yellow band-like interspace. The lower 
of the blackish bands is confluent with the upper on the side of the 
vent. The lower parts are brownish-yellow, with a pair of darker 
longitudinal streaks, flanking the abdominal shields. There is a 
series of white or faint rose-coloured, posteriorly black-edged, spots on 
each side between the ventral and the lower lateral band ; they form 
very distinct and elegant markings in the younger specimen, where 
they are continued to the vent, forming altogether twenty-four pairs; 
some of them are opposite to those of the other side, others alternate 
with them. These spots are less bright in the old specimen, and 
distinct only on the anterior part of the belly. The lower lip has a 
yellowish margin, and there are two wavy yellow lines along the 
throat. . 
Duméril made a mistake in suggesting that Herpeton has a long 
and grooved posterior maxillary tooth, like the snakes of his family 
of “ Platyrhiniens.” All the teeth are of equal length, and not one 
is grooved. They are of moderate strength and somewhat closely 
set, and there are ten in the upper, and as many in the lower jaw. 
The series of the palatine and pterygoid bones is formed of fifteen 
or sixteen. Another very remarkable peculiarity is found in the 
structure of the intestines, which in the posterior third of the length 
of the trunk form a big mass of twelve or thirteen convolutions. 
Having found the same in dcrochordus javanicus, I do not hesitate 
to remove Herpeton from Homalopsis and the genera allied to it 
(which have the usual simple intestinal tractus), and to place it be- 
side Acrochordus. Hornstedt has found undigested fruits in the sto- 
mach of the latter.
