ZOOLOGICAL RESULTS OF A TOUR IN THE FAR EAST. 
BATRACHIA. 
By N. Annandale. D.Sc, F.A.S.B. {Zoological Survey of India). 
This paper is a batrachiological miscellany, founded only in part on the results 
of my tour in the Far East but treating solely of species from eastern Asia. I have 
taken the opportunity to discuss a number of Indian frogs of the genus Rana about 
which confusion exists in literature or in collections and to describe or annotate 
certain tadpoles from Burma, Ceylon and other countries that lie east of the Bay of 
Bengal. 
No effort was made on my tour to obtain a general collection of Batrachia and, 
indeed, few localities were visited that would have been likely to yield specimens 
interesting in themselves. From a geographical point of view, therefore, the only 
district on which my results cast a definite light is that immediately round the Tale 
Sap in the Siamese Province of Sunk! a or Singgora. This lake is connected with the 
Gulf of Siam and lies in the north-eastern part of the Malay Peninsula ; except for 
small rocky islands and groups of low hills, the shores are flat and devoid of thick 
jungle. The frogs and toads are, therefore, lowland species widely distributed in 
open country. The following species are represented in my collection from this 
district : — 
Species from the Shores of the Tai,e Sap. 
Oxyglossus lima (Gravenh.), Microhyla ornaia (D. and B.), 
Oxyglossus laevis, Giinther, Microhyla achatina (Boie), 
Rana cancrivora , Gravenh., Kaloula pulchra, Gray, 
Rana cyanophlyctis , Schneid., Bufo melanostictus , Schneid. 
The most interesting of these species geographically are R. cancrivora (an essen- 
tially Malayan frog accompanied in continental Siam by the allied, but not very 
closely allied, R. rugulosa) and R. cyanophlyctis , the precise geographical distribution 
of which outside India (in which it is universally distributed at low elevations) is 
still very imperfectly known. The only previous record of the latter from the Malay 
Peninsula depends on specimens from Cantor's collection — a notoriously corrupt 
source — labelled as being from Penang. 
FROGS OF THE RANA TIGRINA GROUP, 
Under this heading I propose to consider three forms that seem to me to be 
distinct species ; they have been confounded under the name Rana tigrina by recent 
herpetologists. They are Rana tigrina, Daudin, R. rugulosa, Wiegman and R.
