84. Contributions to Oriental Herpetology. |March, 1905. 
The possession by the males of this species and of P. 
siamensis, Blgr., of preanal pores marks the two forms off as 
constituting a very distinct section of the genus Phyllodactylus, 
if not aseparate genus. I take this opportunity to figure certain 
structural details, as P. ewropeus is the only other species of which 
I have examined specimens. P. stamensis and P. burmanicus are the 
only forms known from the Indian Region. 
HMIDACTYLUS TRIEDRUS (Daud.) (Plate II, fig. 2).

There is a fair series of this Gecko in the Indian Museum, 
but unfortunately most of the specimens are without localities. 
One labelled “near Ellore” and named, apparently by Stoliczka, 
Hemidactylus subtriedrus, agrees closely with Jerdon’s description 
of that species, which, however, is not definitive. It agrees with 
Boulenger’s definition of H. subtriedrus in haying ten labials, a 
head more depressed than that of typical specimens of H. triedrus 
and rather smaller ventral scales ; but it differs in having only seven 
infradigital lamelle under the thumb, nine under the middle finger, 
and nine under the middle toe. It may, therefore, be regarded as 
intermediate between the two forms. The fact that it is from 
the Ellore district suggests the possibilty that other specimens 
of an intermediate character occur and that H. subtriedrus is not 
specifically distinct. Possibly it is one of the two specimens 
referred to by Stoliczka in the reference quoted; but it is not the 
one figured. Its donor’s name was originally omitted in the 
Museum register, but “ Dr. Stoliczka” has been written in in pen- 
cil at a later date. 
HEMIDACTYLUS KARENORUM (Theob.)

some little distance off the east coast of Sumatra, by the late 
~ Prot. J. Wood-Mason’s collector :— 
1. Gymnodactylus fee, Bler. (3 specimens). 
2. Hemidactylus frenatus, Gray (numerous specimens).
