tween tlio hind limbs. The band on the neck is darkest. The edges of all are 
darker and more irregularly undulating in front than behind ; a yellow black 
edged band passes from the nostril to the eye, slightly continuing behind, 
the lower black margin is the more distinct one and continues through the 
ear to the cross band on the neck, with the anterior black margin of which 
it is confluent ; upper half of orbit and some spots below eye yellow ; head 
pale, uniform ; tubercles on back yellowish, those on the edges of all the 
blackish bands and at the sides of the belly more distinctly so, brightest on 
neck ; limbs unspotted ; below yellowish, all scales minutely punctated. 
In spirit the whole of the yellow coloration has turned pure white and the 
dark bands are now white edged.

It is, I think, clear that Dum. and Bibron, when describing their II. 
maculatus, had under examination the two forms which Gunther separated, 
and for one of which (considered as the young by D. and B.) he retained 
Dum. and Bibron’ s name. The two forms arc, no doubt, extremely closely 
allied, and it has yet to be satisfactorily proved, whether H. Pieresi should 
more appropriately be considered as a large local variety of maculatus, or as a 
distinct species, but, I believe, the view taken by Kelaart and Gunther, and 
first of all by Gray, is the correct one. It is certain that maculatus, as restricted 
by Gunther, never appears to attain on the continent of India and Burma a 
larger size than 5) inches, and this measurement was observed only in two 
cases among about 200 specimens from South India, Central India, N. W. 
Provinces, the Sub Himalayan hills, and almost all parts of Bengal, Burma and 
the Andamans. The usual size is 4 or 4) inches. 
In all these specimens the head and body is brown spotted, the 
spots on the latter have a tendency rather to arrange themselves in 
longitudinal than in cross series ; in the three median rows the spots are 
larger and more distinct than at the sides, where they generally become 
rather confluent. The brown spots are equally distinct, or equally indis- 
tinct, in males and females, the variations apparently depending upon the 
seclusion of the locality in which the lizards live. However, I have repeatedly 
observed, that in specimens which bad the tail reproduced, the brown spots do 
not retain the same distinctness which they had before. South Indian speci- 
mens are generally of dark hue, and often have some of the enlarged tubercles 
white. Young specimens are always dark brown, with still darker spots, 
while the majority of the enlarged tubercles is purely white. 
As regards structure I find the enlarged tubercles slightly vary. They are 
always well marked, along the back distinctly trihedral, on the sides often more
