Hemidacttltts. 
I liave observed in several hundreds of specimens of different species of 
Hemidactylus, (as restricted, and of the section Doryurd ) , as well as hi the 
allied genera Peripia and JStycteridium, that the total absence, or the presence, 
of a few enlarged tubercles does not constitute a sufficiently distinct specific 
character. The variations in this respect cannot be accounted for either 
by age, sex, or the locality, but they are simply accidental. The species 
belonging to the section Doryura have generally a nearly uniformly granular 
body, well developed paratoid glands and normally a smooth tail, while in 
Hemidactylus the tail is normally spiny, but, when reproduced, it becomes 
smooth. 
The distribution of the Indian and Burmese species of Hemidactylus 
is the following : 
1. H. TBtEDEtrs, Daud. (I. B,., p. 107). Ceylon, South and Central 
India (Bundelcund).* 
Nothing reliable is as yet known about the form for which Jerdon 
suggested the name H. subtriedrus (Jour. A. S. B., Yol. xxii, p. 467). 
(see pi. ii, fig., If). 
It is perhaps not specifically different from triedrus, but there certainly 
exist some forms which possess the distinctive characters noted by J erdon of 
his subtriedrus. Mr. W. T. Blanford kindly allowed me to examine two 
specimens which he lately collected near Ellore, and which, although agreeing 
in form, general structure and coloration with triedrus (for instance the figure 
in Belanger’s Voyage), differ somewhat from the description usually given 
of that species. The two specimens are both females, apparently not full 
grown, and measuring on the average 4^- inches, of which the head is about 
f inches, and rump lj inch. None of the tubercles on the back is as 
large as the opening of the ear ; the head does not appear to bo shorter than 
in typical triedrus, but the scales on muzzle and throat are certainly very 
small ; a great nmnber of moderately enlarged tubercles on tho hinder part of 
the head ; two enlarged shields behind the rostral separated by two small 
azygous shields ; nostril situated between rostral, suprarostral, first labial and 
two moderate shields behind ; 10 to 12 upper labials, not constant, a row of 
conspicuously enlarged scales above them ; 10 very distinct and well 
developed lower labials ; 2 pairs of chin-shields, first forms a suture ; 32 long 
rows of scales across the middle of the belly. The coloration, which was 
noted by Mr. Blanford during life is : body generally bluish grey with 5 olive 
brown, black-edged bands on the body and about 6 on the tail : of the 
former the first is situated on the neck, 2nd on the shoulder and the last be-
