Remarks. In the restriction here adopted, this genus is chiefly charac- 

 terised by the somewhat dilated and depressed anterior division of the body, the 

 rather full development of the outer ramus of the posterior antennae, and partly 

 also, by the structure of the 2 pairs of maxillipeds and the last pair of legs. 

 Two well-defined species of this genus occur off the Norwegian coast.

Specific Characters. Female. Anterior division of body moderately dilated, 

 greatest width scarcely attaining half the length; rostral plate slightly deflexed 

 and narrowly rounded at the tip. Epimeral plates projecting behind in an acute 

 corner. Urosome exceeding half the length of the anterior division, last segment 

 deeply cleft. Caudal rami a little longer than they are broad, and considerably 

 divergent, apical setae of moderate length. Anterior antennae short and thick, 

 consisting of 7 well-defined articulations, the penultimate one with a remarkably 

 strong seta in front, last joint very small, nodiform. Anterior maxillipeds with 

 the 2nd basal joint smaller than the 1st, unguiform spine not very strong. Last 

 pair of legs rather distant the one from the other, marginal spines very unequal, 

 some of them rather slender, setiform; distal joint well defined, though compara- 

 tively small, subquadrangular, with the outermost apical spine much smaller than 

 the other 2, appendicular bristle slender and elongated; inner expansion of proximal 

 joint with 2 unequal spines at the tip. 



Colour whitish gray. 



Length of adult female 0.90 mm. 



Remarks. This form was first recorded by Boeck, and subsequently de- 

 scribed and figured by Prof. Brady in his well-known Monograph. It is easily 

 recognizable from any of the other species referred by Mr. Scott to this genus, 

 both by the outer habitus and by some of the anatomical details. 



Occurrence. I have met with this form in several places on the Norwe- 

 gian coast from the Christiania Fjord to Trondhjem Fjord. Mr. Th. Scott records 

 it also from Finmark. It occurs in depths ranging from 10 to 30 fathoms, 

 muddy bottom. 



Distribution. British Isles (Brady, Scott).
