its awkward attempts at hopping w^hen it moves, do not 

 tend to render it a general favourite, any more than its per- 

 sonal beauty. 



F, — These are all the species that I can mention as 

 common ; but there is another which I suppose to be 

 quite rare, or, at least, seldom met with. About this time 

 last year, I saw on a raspberry bush a small frog, about an 

 inch and a half long ; as near as I can recollect, it was of a 

 pale brown or drab colour ; it was very active, leaping from 

 leaf to leaf. It attracted my attention by its unusual 

 situation, and by the tenacity with which it clung to the 

 leaves, always adhering where it alighted, without any

 were furnished with round, dilated, membranous suckers; 

 from which circumstance I have since discovered that it w^as

 of the leaves and branches, which may be a reason why 

 they are so seldom seen. 



C. — See, see ! there is a little animal leaping like a kan- 

 garoo through the grass.

 fore ones, and it usually moves by long leaps, as that which 

 you have just seen ; I believe, however, they put their fore 

 feet to the ground when not disturbed : the tail is very long. 

 They are often seen in mowing and in reaping: I have
