“The larva has been first noticed by me, from specimens from 
Sumatra and Perak, and others have since been obtained in 
Selangor by Mr. Butler, and in Perak by Dr. Hanitsch. These 
tadpoles are of the same type as the typical Pelobatids of Europe, 
but remarkable in being marked all over with numerous deep 
black dots or round spots. No observations have been made on 
the breeding-habits, but it is probable that the eggs are laid in 
the water, being similar to those of Pelobates. Eggs from 
the oviducts of a female 65 millim. long measure 2 millim. in 
diameter. 
“Mr. A. L. Butler observes (Journ. Bombay N. H. Soc. xv. 1904, 
p. 397) that the larval period of existence is very prolonged, 
and that the tail does not disappear until the size of about 40 
millim. (from snout to vent) is attained.”
