the Madras Presidency, and I find that, although the majority 
resemble the typical specimen in the absence of any enlarged 
tubercles on the back, a few are occasionally found with such 
tubercles, and that the form is only a small variety of H. Leschen- 
aultid, with uniform or nearly uniform granulations. 
The largest specimens I have as yet obtained of Hemidactylus 
marmoratus measure 5.2 inches of which the tail from the anus is 
exactly one half or 2.6. H. Leschenaultit grows to a larger size 
than this. I find in 4 specimens of the latter that the number of 
scales across the abdomen are respectively 36, 39, 59, 42, and the 
upper labials from 10 to 13, (usually 11 or 12,) lower labials 7 to 9, 
(8 being the prevailing number). In 4 specimens of the variety 
marmoratus, the scales across the abdomen vary from 34 to 42, 
(the numbers are 34, 38, 39, 42,) the upper labials vary from 10 to 
12, the lower from 7 to 9. The femoral pores are quite as constant 
in number as either the scales across the abdomen or the labials, 
they are usually 12 in each thigh, but occasionally vary between 
10 and 14. 
From these differences, it is manifest that Hemidactylus Kelaarti, 
Theobald, must also be considered a variety of H. Leschenaulti. 
AsI had, guided by Ginther and other eminent herpetologists, 
attached a higher value to the presence or absence of enlarged 
tubercles on the back of this group of Hemzdactyli, than the charac- 
ter deserves, it is probable that some of my other identifications 
on page 364 (loc. cit.) are incorrect. 
I was in error in including <Adlabes Humberti in the fauna 
characteristic of the Malabar province. I have found several 
specimens of a small snake near the lower Godavari which appears 
to belong to that species, and I find that the same form occurs 
near Calcutta. The only important difference between specimens 
from the different localities is in the number of ventral scales, 
which I find to be 155 in a Malabar specimen sent by Major Bed- 
dome to Dr. Stoliczka; about 210 in specimens from Ellore, and 
no less than 240 in one from Calcutta. This is a remarkable de- 
gree of variation certainly, and there is a corresponding difference 
in length, the snakes from Bengal and Ellore being more elongate. 
Dr. Giinther, I should add, found the number of ventral scales to 
be 175.
