Peripia might, like Doryura, he considered as a subgenus of Hemidac- 
tylus. It connects Doryura with Nycleridium , having the general form and 
usually flattened pointed tail and small equal granular scales of the former, 
while the toes are distinctly webbed at the base, and there is also a distinct 
expansion of the skin at the hinder side of the femora and tibise. In Nycteri- 
dium only the lateral expansion of the skin of the body is added to the 
character of Peripia. If we characterize the later genus from the two Indian 
species, P. Peronii and Cantoris, we cannot say that the thumb and inner 
toe are without an ungual phalanx. I have examined very numerous 
specimens of the former, and a few of the latter species, and I find that the 
ungual phalanx on the thumb is very nearly, hut never entirely obsolete, it, 
however, always appears to be clawless. On the inner toe the ungual phalanx 
is extremely small, but in nearly all my fresh specimens I find there is a very 
minute, thin, transparent, setiform claw present ; only in some old specimens 
I have not been able to detect it. 
P. Cantoris occurs in Penang, Burma, the Andamans and Nicobars ; 
from all the localities I have examined specimens. 
P. Peronii is very common on Penang,* and in the Wellesley Province, 
rarer in Burma and on the Andamans. The type was from Mauritius, and ac- 
cording to Kelaartf it is also found in Ceylon. Andamanese specimens agree 
in their very distinct brown tinge with those from the two later islands, while 
Penang specimens are brown, when young, but when adult usually greenish 
ashy, rarely with a rosy tinge. Two adult fresh specimens from the Andamans 
perfectly agree in structure with those from other places ; the general colour 
above is pale chocolate brown with a rosy tinge, all over speckled with darker 
brown and with numerous round white spots, about a m.m. in diameter ; below 
white, pinkish towards the sides, and all scales minutely punctated.

I have Asam, as well as Himalayan (from near Darjiling) specimens 
for comparison, and they certainly belong to the same species. They also do

J Gray’s name Platywms certainly has the same derivation, as Platimis, and as it 
has been at an early date replaced by Nyctmdium, it seems advisable not to revive the 
former name, particularly as it would involve a change in the specific denomination, 
and may besides lead to misunderstanding.
