GAMMARIDiE. 
short and very robust; the fourth joint has the inferior 
margin considerably produced anteriorly upon the wrist ; 
the wrist is short, very short upon the inferior margin, 
and arched upon the upper, forming an imperfect tri- 
angle ; the hand is not so broad as the wrist, and 
gradually tapers to the distal extremity ; the palm cor- 
responds with the inferior margin, and is imperfectly 
defined ; a short spine marks the limit to which the 
finger can reach, which corresponds nearly with the en- 
tire length of the inferior margin. The second pair of 
legs are long, slender, and membranaceous ; the third 
joint is as long as the fourth; the wrist is as long again 
as the hand ; the hand increases in width towards the 
distal extremity ; the palm is furred with minute hairs ; 
and the finger is very minute. The first two pairs of 
walking legs are tolerably slender, whilst the last three 
are very short and robust ; the second or squamiform 
joint is of an oval shape, and is inferiorly produced as 
far as the distal extremity of the third joint, and the 
posterior margin is slightly crenulated. In Kr oyer’s 
figure this is not so represented, the margin being drawn 
smooth. The three posterior pairs of caudal appendages 
are short ; the peduncles are stout, and increase in dia- 
meter posteriorly upon the upper margin ; the branches 
are short, and free from hairs. The central terminal 
plate is round, only showing a slight depression at the 
apex. 
The specimen from which we drew our figure and de- 
scription was sent to us by Mr. Edward, of Banff, who 
procured it in that neighbourhood.
