Remarks. This form was described by Th. Scott in the above quoted 

 paper as a species of the genus Ameira. It cannot, however, by no means be 

 referred to that genus, as defined by Boeck, differing, as it does, very essentially 

 both in its outer appearance and in the structure of the several appendages. Nor 

 can it in my opinion be referred to any of the other genera comprised within 

 the present family, for which reason I have felt justified to establish for its reception 

 a new genus. 



Occurrence. I found this peculiar form many years ago in the upper part 

 of the Christiania Fjord at a depth of about 30 fathoms, muddy bottom, and I 

 have recently also collected it in another place, viz., at Farsund, south coast of 

 Norway in about the same depth. In none of these places it occurred in any 

 abundance, but only quite occasionally. No trace of any true eye could be 

 detected in the living animal. 



Distribution. Scottish coast (Scott). 



148. Stenocopia setosa, G. 0. Sars, n. sp. 



(PJ. CLIII & CLIV). 



Specific Characters. Female. Body somewhat less slender than in the 

 preceding species, with the anterior division broader than the posterior, and 

 having the segments sharply marked off from each other, with conspicuous lateral 

 incisions between them. Integuments very thin and pellucid, being clothed both 

 at the hind edge of the segments and laterally with slender curved hairs. Cephalic 

 segment comparatively short and broad, exhibiting on each side behind a knob- 

 like setiferous prominence, rostral projection very slight, almost obsolete. Urosome 

 (including the caudal rami) about the length of the anterior division, but rather 

 narrower, genital segment projecting at the base on each side to a rounded pro- 

 minence clothed with hair-like setse, last segment larger than the preceding one, 

 and carrying behind, to each side of the anal fissure, a remarkably long and 

 slender hair pointing straight behind, anal opercle finely ciliated at the edge. 

 Caudal rami about the length of the 2 posterior segments combined, and very 

 narrow, linear in form, apical setse much elongated. Anterior antennae resembling 

 in structure those in the preceding species, though not fully as long, proximal 

 part scarcely attaining twice the length of the terminal one. Outer ramus of 

 posterior antennae rather small and uniarticulate, with only 2 unequal apical seta3. 

 Oral parts agreeing in structure perfectly with those in the preceding species. 

 1st pair of legs, however, of comparatively larger size, outer ramus shorter than 



30 Crustacea.
