Remarks. In this new genus I propose to include some species formerly 

 referred to the genus Cletodes, but differing very materially from the type of that 

 genus, both as regards the outward appearance and several of the structural de- 

 tails, thus forming together a very natural generic group. Among the distinguishing 

 characters may be noted: the total absence of eye, as proved by the examin- 

 ation of living specimens, the feeble structure of the posterior antennae and oral 

 parts, and finally the presence in the female of 2 ovisacs. 4 Norwegian species 

 will be described below.

Specific Characters. Female. Body short and compact, with the segments 

 scarcely denticulate at the hind edge. Cephalic segment about the length of the 

 3 succeeding segments combined, and produced in front to a rather prominent 

 conical rostrum acutely pointed at the tip. Urosome remarkably broad, even 

 broader than the anterior division, with none of the segments produced at the 

 lateral corners, last segment exceeding in length the 2 preceding ones combined; 

 anal opercle, as also the ridges leading to it from behind, armed with very coarse 

 obtuse denticles. Caudal rami rather narrow, tapering somewhat distally, and 

 more than twice as long as they are broad at the base, dorsal seta issuing at a 

 short distance from the end, middle apical seta scarcely more than twice as long 

 as the ramus itself. Anterior antennae about the length of the cephalic segment, 

 and having the 2nd joint fully as long as the 3rd, terminal part about the length 

 of those joints combined. Posterior antennae with no trace of an outer ramus, 

 terminal joint considerably shorter than the basal one, and scarcely widening 

 distally. Posterior maxillipeds with the dactylus very slender and elongated. 1st 

 pair of legs with the terminal joint of the outer ramus larger than the middle 

 one, and armed with 3 spines and 2 curved seta?; inner ramus almost as long 

 as the outer and biarticulate, distal joint with a small seta inside and carrying 

 at the tip a short spine and 2 unequal seta?. The 3 succeeding pairs with the 

 inner ramus distinctly biarticulate and of a structure similar to that of the 1st 

 pair. Last pair of legs with the distal joint obovate in form, tapering gradually 

 towards the end, and provided with 5 rather slender sub-equal setse; inner ex- 

 pansion of proximal joint very short, with 3 slender setse. Ovisacs well defined,
