trical markings; back with angular dark brown spots; sides 
marbled with dark brown; limbs with regular dark cross-bars. 
Male with subgular vocal sac, and the throat black.” It is a 
native of Surinam and North Brazil. 
The Adorned Ceratophrys or Esquerzo (C. ornata) has not 
nearly so large a horn-like appendage as the last-mentioned 
Batrachian. It possesses vomerine teeth, a very laige head, 
which is rough and bony: the nostril is nearer to the eye, which 
is fairly large, than the end of the snout; a bony dorsal shield ; 
stout fingers and toes, the latter being only half-webbed. The 
upper surfaces of the Frog’s body are covered with small tubercles, 
and the lower surfaces with granules. The upper parts of the 
body are bright green in colour, marked with large, light-edged 
olive spots ; the edge of the lower jaw is bright yellow; a yellow 
line runs from eye to eye; the upper surface of the hands and 
feet is yellowish; there are sometimes red lines between the 
spots on the back; the tongue is flesh-coloured. It is a native of 
Buenos Ayres and other parts of South America. 
Mr. Hudson also says, in the article referred to above, that 
“The country people in South America believe that the milky 
secretion exuded by the Toad (the Ceratophrys, I suppose) 
possesses wonderful curative properties. It is their invariable 
specific for shingles, a painful and dangerous malady common 
amongst them; and to cure it living Toads are applied to the 
inflamed part.” 
The Slender-fingered Frog (Leptodactylus pentadactylus). The 
members of this genus are known as ‘‘ Piping’ Frogs because of 
their peculiar pipe-like croak, which differs in power and pitch 
according to the species. They are natives of Tropical America, 
and in general appearance much resemble the Common Frog. 
As they are occasionally imported into this country, it is wise, I 
think, to give a brief description of one or two species. 
The manner of depositing the eggs by certain of these Frogs 
is peculiar and interesting. A hole is dug in the ground near 
to the water’s edge. The little cave is then lined with a kind 
of frothy secretion, to which the eggs are attached until they are 
hatched. It is said that these caves or holes are so situated that 
at some period or other during the process of hatching they are
