THE eyes are small. The antenne are subequal, the superior 
pair nearly half the length of the animal: first joint of the 
peduncle rather longer than the cephalon; second rather 
longer than the first; the secondary appendage being small. 
The inferior antenne are shorter than the superior, having 
the peduncle rather longer than the peduncle of the superior. 
The gnathopoda are armed with fasciculi of hairs; first pair 
having the propodos ovate, with the palm waved and imper- 
fectly defined, furnished with several fasciculi of long cilia; 
dactylos serrated along the inner margin. Second pair having 
the carpus almost as long again as the propodos ; propodos 
tapering; dactylos apical, minute. The pereiopoda are long, 
slender, and cylindrical. The pleopoda have the antepenultimate 
pair longer than the penultimate ; the penultimate longer than 
the ultimate; ultimate scarcely reaching beyond the telson. 
Telson circular. 
This species was taken by the Rev. Mr. Norman off Holy 
Island, on the coast of Northumberland and Durham, and 
named by him U. planipes in the Transactions of the Natural 
History Society of Northumberland and Durham. We had 
previously received it from the Haaf Ground, Shetland. We 
believe, however, that the species probably is identical with 
Kroyer’s Greenland species, the distinction between the two 
arising from omissions in description and figure rather than 
any clear variation of character.
