The tibial process of the first pair of perceopoda does not reach to the base of the carpal 

 process; the front margin of the carpal process is serrated, almost as long as the hind 

 margin of the metacarpus; the dactylus is not serrated. The carpus of the third and fourth 

 pairs is not dilated; the hind margin is straight, serrated. The last three pairs are not 

 longer than the two next preceding pairs; the femur is narrow; the metacarpus is medi- 

 ocre, not longer than that in the third and fourth pairs. The first pair of uropoda are 

 far from reaching to the apex of the last pair; the outer ramus is much shorter than the 

 inner. The telson equals about a third of the length of the peduncle of the last pair of 

 uropoda. 



Colour. Yellowish. 



Length. About 5 mm.

As seen from the list of synonyms above G. 0. Sars in 1882 regarded the species in 

 question as identical with 0. Fabkicius' (and Kroeyer's) species which he, following Boeck, 

 named Tauria rnedusarum, 0. Fabricius. From the diagram given above, p. 91 and 92, 

 it is clear, I suppose, that they are two distinct species. Hyperoche abyssorum is 

 more closely allied to H. Luetkeni than to H. Kroeyeri; with both it has in common the
