UNCIOLA LEUCOPE?*. 



Specific character. Upper antennae nearly half the length of the animal. 

 Secondary appendage minute. G-nathopoda fasciculated. Terminal pleopoda 

 armed with short strong spines. 



Length, one-third of an inch.

The eyes are small. The antennae 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 antenna} 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 denned, 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.
