GAMMARIDvE. 
impinges against the two small teeth at the base of 
the palm. The animal, in other respects, closely re- 
sembles M. monoculoides, except that the terminal scale 
of the tail is more pointed. The colour of the animal, 
when alive, is yellowish, or pale flesh-colour, several parts 
of the body and coxae marked with faint blotches of 
light rose, or pink. The structure of the integument is 
very free from any decided markings ; but the surface is 
in different parts furnished with very minute cilia, which 
are nowhere thickly planted. 
We have received specimens of this species from the 
coast of Northumberland, from Mr. Joshua Alder; also 
from Banff, Mr. Edward; and from Macduff, from Mr. 
Gregor ; we have found it ourselves amongst some trawl 
refuse brought to us from near the Eddystone Light- 
house. 
We have also received a specimen, which we consider 
to he only a variety of this species, from the coast of 
Piedmont, collected by Mr. Gwynn Jeffreys : it varies 
from the type in having the palm of the second pair 
of legs somewhat less than the entire length of the hand. 
This specimen was taken upon the shore, whereas all 
those recorded as British have never been taken in 
less than ten fathoms of water — a circumstance not of 
much importance in itself, hut as adding to the testimony 
of the late Professor Edward Forbes, that species taken 
in the deep sea in northern latitudes, when they exist 
near the equator, inhabit shallow water.
