From the above it would appear that this change of shape 
takes place in larvae, obtained during December at about the 9 
p.c. stage but in the 14 p.c. stage in those existing during the 
month of February. 
Another point that seems worthy of note is the season at 
which these larvae were obtained. Both Brooks and Yatsu ob- 
tained their specimens during the month of August and, according 
to the latter observer, in Japan the breeding season extends from 
July to the end of August, and at no other period of the year are 
larvae to be found. The occurrence of larvae during the winter 
months in the plankton off the Burma coast may be due to 
either a local peculiarity or possibly to the existence of two breeding 
seasons during the year, one in the summer months July and 
August, and a second from December to February, but in 
either case I attribute the delay in the formation and protrusion 
of the peduncle and the change in shape of the shell to the less 
favourable time of year at which the development was taking 
place.

Notes on the distribution of some Indian and Burmese Lizards :— 
I. DISTRIBUTION OF Liolefis IN THE INDIAN EMPIRE.—The 
large and conspicuous lizard Liolepis belliana, Gray, is a character- 
istic feature of sandy tracts in Tenasserim and has been stated to 
occur in South Canara. Careful inquiries have convinced me, how- 
ever, that it does not occur anywhere west of the Bay of Bengal 
It is very unfortunate that many of the older records of the 
occurrence of both reptiles and other animals in the Madras Presi- 
dency are equally unreliable. This is owing to two causes :—(i} 
A considerable number of Burmese specimens have, in at least 
one instance, been mixed with collections from S$. India and ali 
have been attributed to the latter. This has been pointed out 
by Major F. Wall as regards certain snakes, and it is undoubtedly 
the case also as regards Liolepis belliana. It is a particularly unfor- 
tunate occurrence, because there is an actual affinity between the 
faunas of the mountains of S. India and the countries east of the 
Bay of Bengal which such mistakes tend to obscure. (ii) In a 
large number of cases specimens have found their way into public 
collections labelled not with the name of the locality in which they 
were originally found but with that of the locality of the institution 
from which they were sent to specialists or museums in Europe. 
Certain missionary colleges are largely responsible for such mis- 
takes, and old records of such localities as Trichinopoly are worth- 
less, unless they have been recently corroborated. 
2. THE DISTRIBUTION OF Mabuia bibroni (GRAv).—This very 
distinct little skink is stated, vaguely, in the “‘Fauna’’ to 
occur in the ‘‘ Carnatic,’’ but the real interest in its distribution
