The hand of the second pair of gnathopoda is smaller in 

 proportion than that of the male in other species, which, 

 together with the size of the animal, incline us to believe the 

 specimen to be a not yet fully grown animal. 



We are indebted for this species to Mr. Edward, who took 

 it near Banff. Its eyes are black, and its colour a light 

 olive-green. It probably has been passed over for the young 

 of the more common species.
