Occurrence. Only some few female specimens of this form have hitherto 

 come under my notice. They were collected from some samples taken off the 

 south coast of Norway, at Risor and Farsund, from moderate depths. 



Gen. 48. Paramelra, G. 0. Sars, n. 



Generic Characters. Body comparatively short and stout, cylindrical in 

 form, with rather thin and pellucid integuments. Cephalic segment not very large, 

 rostral projection obsolete. Urosome unusually thick, and scarcely at all attenu- 

 ated behind, segments only spinulose at the hind edge ventrally; anal opercle 

 smooth and more or less projecting. Caudal rami small. Eye wholly absent. 

 Anterior antennae comparatively short, 8-articulate, with the setse of the anterior 

 edge stout and curved, in some cases plumose. Posterior antennae with the basal 

 part imperfectly subdivided, outer ramus small, uni- or biarticulate. Mandibular 

 palp simple, biarticulate, proximal joint scarcely expanded inside. Maxillse and 

 maxillipeds about as in Ameira. 1st pair of legs imperfectly prehensile, inner 

 ramus somewhat longer than outer, and 3-articulate, with the 1st joint much 

 shorter than the other 2 combined, the latter scarcely at all bent upon the 1st. 

 Natatory legs with both rami well developed, 3-articulate, last joint of outer 

 ramus in the 3rd and 4th pairs of legs and that of the inner ramus in the 3rd 

 pair with 3 setse inside. Last pair of legs with the distal joint narrow, inner 

 expansion of proximal joint comparatively short. 



Remarks. This new genus is nearly allied to Ameira, yet differing in 

 the less slender form of the body, the want of any distinct rostrum, and also in 

 a somewhat different s-tructure of the antennas and legs. Two Norwegian species 

 will be described below, and I am now of opinion that also the form described 

 above as Ameira simplex Norm, should more properly be referred to this genus. 

 Moreover the 2 species recorded by Th. Scott as Ameira reflexa and A. longi- 

 remis are undoubtedly congeneric with those here described.
