and lower margins parallel ; the palm is oblique, that of 
the right hand being developed into the form of a small

armed with a strong tooth near the centre, and a smaller 
one which defines its posterior limit. The walking legs are 
all of the same length, being tolerably long and rather 
slender; they have the thighs not developed, and the 
penultimate joint of the last three pairs are serrated upon 
the inner margin. The caudal appendages are short, 
and each terminates in short branches. 
We know nothing of the habits of this creature,

Mr. Edward, who took it near Banff. 
The following sketch of Covesea Lighthouse, on the

Miss Gordon Cumming, of Altyre.
