setse, carpal joint in all pairs rather short, propodal one slightly tapering, 

 daetylus short and curved. First pair of nropoda with the rami scarcely 

 lialf tlie lengtli of the basal part, inner ramus somewhat broader than the 

 outer, and armed at the end witli 3 sliort spines; 2nd pair with the basal 

 expansion in female very broad, subquadrate, and coarsely serrated at the 

 edge, in male linguiform produced and densely hirsute, rami in both sexes 

 very sliort, sublamellar, and having at the end 5 or 6 serrations; last pair 

 with the inner ramus extremely minute and concealed by the outer, tlie latter 

 in female very broad, oblong oval in form, and serrated on the edge, in male 

 about twice as long, and narrowed distally. Telson subcarinated dorsally,

Ttemarl's. — This peculiar Amphipod was first described by Philippi, 

 and has subsequently been recorded by several other authors. The Newerfes 

 nesceoifles of White is identical with this form, and the specific name proposed 

 by that author refers to the external resemblance, in the configuration of the 

 posterior part of the body, to the genus Nescea, belonging to the Sphaeroinid 

 group of Isopoda. The CJiehira xwntica of Czerniawsky does not seem to 

 differ in any points from the typical species. As to the uropoda, Boeck 

 erroneously describes the 2nd pair as the 1st, and vice versa. 



Occurrence. I have myself met with only a single female speci- 

 men of this form, which was found together with other Amphipoda collected 

 in the Christianiafjord. Boeck found it in great numbers in a submerged 

 log at Moss, and there are also in our Museum some specimens from Karmo, 

 west coast of Norwaj'. In every case the habit of this animal is stated to 

 be of a similar kind to that of Limnoria, it being, in nearly every instance, 

 found in submerged timber, in which, like that animal, it burrows, tearing 

 the loose, woody substance. 



Distrihntion. — British Isles (Sp. Bate), Dutch coast (Hoek), Adriatic 

 (Philippi). Black Sea (Czerniawsky), Atlantic coast of North America 

 (S. Smith).

Body more or less slender, with very small coxal plates. Metasome gene- 

 rally poorly developed; urosome having the last segment generally imperfectly
