sure to be flooded with water. In general appearance, there is 
not much difference between the tadpoles of this genus and those 
of the ordinary water Frogs of Europe. 
The Slender-fingered Frog possesses an oval tongue, which is 
slightly nicked behind ; vomerine teeth, which are placed in two 
arched series beyond the apertures of the inner nostrils; and a 
tympanum nearly as large as the eye (the pupil of which is hori- 
zontal). The hind toes are not webbed. The skin is smooth 
above, and there are generally large flat glands upon the flanks. 
The following is the description of the colouring of this Frog 
as given by Mr. Boulenger in his ‘‘Catalogue of Batrachia 
Salientia”’: ‘‘Brownish above, with dark spots generally ar- 
ranged in transverse bars on the back; a black stripe along the 
canthus rostralis and the temporal fold; limbs cross - barred ; 
hinder side of thighs black and yellowish marbled.”’ 
This Frog is a native of South America, and it may be kept, 
during the warmer parts of the year, in the same case as the 
Common and other Frogs of like size and similar habits. 
The Ocellated Piping Frog (Leptodactylus ocellatus), sometimes 
known as the Bladder Frog, is also a native of South America. 
One of the chief differences between this Batrachian and that last 
described is the fringing of the toes on both sides. The colour 
of the animal is olive or brownish above, which is marked with 
roundish dark spots. There is a large spot between theeyes. The 
Frog shonld be treated in confinement in this country in the same 
way as has been suggested for the Slender-fingered Piping Frog. 
The Australian Frog (Pseudophryne australis) is from time 
to time brought to this countiy, where it lives fairly well in cap- 
tivity. It may sometimes be purchased for so low asum as 5s. 
This Frog has a rounded snout, an eye with a horizontal pupil, 
an elliptical tongue (free behind), and short fingers and toes, 
which are free, and not dilated, at the tips. The skin of the 
creature is either smooth or covered with small, round, flat warts 
on the back. Its colour above is blackish-brown, with a streak 
along the lower part of the back; there is one spot on the upper 
arm, and another on the thigh. The lower parts are blackish, and 
covered with large yellowish spots. It may be placed, while in 
captivity, with other Batrachians of its own size. ,
