It seems probable that Flower's " transparent tadpoles" from Penang are those 
of M. berdmorei^ because they agree with those of other species of Microhyla in 
having a distinct flagellum at the end of the tail,' and because only three species of 
the genus, so far as we know, occur commonly in the Malay Peninsula at low alti- 
tudes; these three species are M. ornata, M. achatina and M. berdmorei, and the 
tadpoles from Penang are very different from those of either of the two former 
species. 
I found numerous specimens in the Botanic Gardens at Penang, both in the 
pool in which those of M . achatina occurred and in a small cistern in a fern-house. 
They differ from the specimens examined by Flower in being rather darker and in 
having the anterior two-thirds of the ventral surface profusely dotted with black 
pigment cells; but this difference is more marked in the specimens from the pool 
than in the others. In the specimens from the pool the tail was suffused with 
bright scarlet. The black streak near the vent is always a very characteristic 
feature. 
In the pool the tadpoles were divided into several .shoals, each of which hung 
level and motionless in mid-water at some distance from the others. In each 
shoal the heads of all the tadpoles were pointed in one direction. Often the forma- 
tion was wedge-shaped with several ranks ^ like that of a flock of wild geese on 
the wing. The front rank of one shoal was often opposed to or at an angle with that 
of another. When they were disturbed the tadpoles scattered in all directions, 
but reassembled almost immediately in their respective shoals. The number of 
individuals in a shoal varied considerably, but was never much more than about 
fifty.
