POUCHED FKOG. Xototrema 



It derives its name from the aspect of the head, which looks as if it was overgrown 

 with lichens. It is generally found among the wild pine trees, and is very active, being 

 able to take considerable leaps. Sometimes it puffs out its body, and causes a kind of 

 frothy moisture to exhale from the skin. This moisture adheres to the fingers like gum, 

 and causes the Fro to leave a trail behind it like that of a snail or slug. 



The colour of the Lichened Tree-Toad is pale red mottled with brown, and having a 

 large patch of the same colour between the shoulders. The muzzle and sides are pale 

 green, spotted with dark reddish brown, and below it is whitish grey, the chin being 

 speckled with reddish brown. The head is flattened, sharply pointed at the muzzle, and 

 studded with sharp bony ridges. Its ordinary length is about four inches. 



ANOTHER species of the same genus, the MARBLED TREE-TOAD (TrachycSphalus 

 marmordtus), is described by the same writer :- 



" One of them was taken in a bedroom at Savannah-le-Mar, one night in October, 

 having probably hopped in at the open window from the branches of a mango tree only 

 a few feet distant. I was surprised at its change of colour, in this respect resembling 

 the chameleon and anoles, or still nearer, the geckos. 



When I obtained it, the whole upper parts were of a rich deep amber brown, with 

 indistinct black bands. On looking -at it at night, to my surprise I saw a great alteration 

 of hue. It was paler on the head and back, though least altered there ; on the rump and 

 on the fore and hind legs it was become a sort of semi-pellucid drab, marked with minute 

 close-set dark specks. When disturbed, it presently became slightly paler still, but 

 in a few minutes it had recovered its original depth of tint. In the course of half an 

 hour it displayed again the speckled dark hue, and now uniformly so, save a black 

 irregular patch or two on the head, and a dark patch between the mouth and each eye. 

 The belly, which was very regularly shagreened, was of a dull buff, not susceptible of 

 change. Its eyes retained their proverbial beauty, for the irides were of a golden-brown 

 tint, like sun-rays shining through tortoiseshell. 



This specimen was about as large as a middling English Frog, being two inches and a 

 quarter in length.
