differentiated in colour. 
At this stage of the tadpole of K. pulchra there is a broad and prominent fleshy 
crest on the surface of the head. I do not understand the lines shown crossing the 
head in Smith's figure (B2); there are certainly no transverse groove or rows of 
glands in the position indicated. 
Development is very rapid, and though doubtless accelerated or retarded by 
favourable or unfavourable conditions, probably does not take longer in ordinary 
circumstances than about a week. I figure three stages of the larva at 24, 36 and 
72 hours after hatching. It should be noted that the younger tadpoles are more 
highly magnified than the older ones. These tadpoles were reared in a small bowl of 
water and development would probably have been more rapid in normal conditions.

This tadpole also has just been described by 
Smith. It closely resembles that of Bufo melano- 
stictus, but can be distinguished readily by the 
fact that the second row of teeth on the upper lip 
is continuous or but very slightly interrupted in the 
middle line. The whole animal is also stouter and 
the tail considerably deeper.

The tadpole of this species appears to be very variable in colouration and pro- 
portions; the number of interrupted rows of teeth on the lower Hp may be either 4
