trace of the animal. At tlie same time it is nothing like so general a form in and 
around water-holes as is C. platycephahis, and whilst the tadpoles of the latter 
were very common, I could not find any of U. pictus —a somewhat remarkable fact, 
as the adult was plentiful in parts. 
In all the specimens obtained after rain the body was very much swollen out, 
due in the main to the fact that the alimentary canal was gorged with food. The 
stomach was always widely distended, occupying the greater part of the body 
cavity and containing caterpillars (the latter were swarming over the ground in 
thousands for a few days after the rain) and beetles; the small intestine was 
pushed to one side, and the rectum was always very much swollen out and filled 
with undigested matter and particles of dirt. Its walls were distended, so that it 
had the appearance of a thin bag filled with dirt. The fat bodies were also very 
largely developed, and altogether the animals looked as if they were simply 
gorging themselves with food preparatory to returning to their pestivating 
condition. 
21ie Tadpole .—Length of body once and two-thirds its width, and about four- 
fifths the length of the tail. Height of the tail rather more than half its length. 
The distance between the tip of the snout and the nose and the latter and the 
centre of the eye equal. 
Eyes on the upper surface not visible from below. 
The spiraculum is on the left side, not very prominent and not visible from 
above. 
The anus opens to the right side of the ventral fin at the base of the tail. 
The beak is not very broadly bordered with black. 
The lips above bordered with a single row of papillae, which ai’e interrupted in 
the mid-anterior line, and longest in the mid-posterior. 
Upper lip with a long series of teeth followed on each side by three series, 
whicn are separated from their fellows on the other, and gradually decrease in 
length. 
Three series of teeth in the lower lip diminishing in .size backwards, the first 
interrupted narrowly in the middle. 
The body is of a light bluish tinge, dorsally when alive with darker mottlings, 
tlie ventral surface and tail crest a yellowish grey.
