of the latter joint, accessory appendage extremely minute. Inferior antennae 

 not much shorter than the superior. Gnathopoda apparently of a similar 

 structure to that in D. porrecta. Basal joint of the 2 anterior pairs of pereio- 

 poda rather much expanded, and oblong fusiform in outline. The 3 posterior 

 pairs of pereiopoda not much elongated, and but sparingly spinons. Uropoda 

 and telson of the usual structure. Colour in alcoholic specimens uniformly 

 greyish white, without any pigmentary ornament. Length of adult female'5'mm. 



Reworks. The present new species, detected by the Rev. Mr. Nor- 

 man, may at once be distinguished from any of the other known species by 

 its unusually small, though distinctly developed eyes, as also by the strongly 

 built and very densely setiferous antennae. In the latter respect it somewhat 

 resembles a species described by the author from the Norwegian North At- 

 lantic Expedition as D. Mrsuticornis ; but in this species the eyes are imper- 

 fectly developed, without any visual elements. 



Occurence. - Some specimens of this form, all of them females, were 

 collected by the Rev. Mr. Norman in the Trondhjemsfjord, at Rodbjerget, and 

 kindly sent me for examination. I have much pleasure in dedicating the spe- 

 cies to that celebrated naturalist, to whom we owe so many valuable papers 

 in different branches of Zoology.
