very muddy pools, both in and around Kimberley. A colony may be heard 
during the daytime at a distance of a mile or more, the noise, which might 
be confused with that of the locust Xiphocera canescens, reminding one of 
castanets. The breeding male has a bright yellow throat. The eggs are 
exuded in a long string, looking much like a string of beads, and during 
this process the breeding pair swim about winding the string of eggs 
around plants or stones. The eggs are appreciably larger than those of 
B. regiilaris. The following notes relate to the metamorphosis as observed 
by one of us. Eggs laid on February 4th morning : by evening, February 
5th, the embryo was 3 mm. long : on the morning of the 6th the tail fin 
had appeared : the following morning the tadpoles 6'5 mm. long, pro- 
vided with external gills, were found clinging to the egg capsule and to the 
sides of the trough : next day, February 8th, the external gills had dis- 
appeared and the gut showed its first coil : by February 10th the 
rudiments of hind-limbs were visible in the shape of minute white buds : 
on the morning of the 11th the total length was 14 mm., and the upper 
surface of the body was dark brown or grey with numerous gold spots 
extending along the sides of the body and the upper half of the tail : by 
February 14th the legs had reached a length of about 2 mm. : on the 15th 
they reached their maximum length, measuring altogether 17 mm. : on 
February 17th the movements of the fore-limbs were distinctly visible, and 
by this time the tadpole had acquired the characteristic whitish spot found 
on the dorsal surface of the body in this species : the tadpoles remained 
quiet at the bottom of the tank, the abdomen began to shrink, and on the 
19th the arms were thrust out : on February 20th the tiny toads, 
measuring only 6 mm. to 8 mm., exclusive of the fast-disappearing tail, 
began to leave the water. 
This is a very rapid metamorphosis, the whole process being completed 
in 16 days.

We are informed that this is a running toad and does not jump. The 
Modder Eiver example was captured at night along with 4 or 5 specimens 
of regularis.
