specimens) dark recldisli lirowii. Superior antennae in female about the length 

 of the cephalon and tlie 1st segment of mesosome combined, flagellnm scarcely 

 longer than the peduncle, 8-articulate, 1st joint as long as the 3 siicceeding 

 ones combined, accessory appendage half the length of the flagellum, 5-articu- 

 late. Inferior antennae in mple fully as long as the body, with the pedun- 

 cular joints considerably expanded. Epistomal plate narrow linguiform, and 

 considerably projecting in front. Anterior gnathopoda very short and stout, 

 propodos about the length of the carpal and meral joints combined, distinctly 

 tapei'ing distally. Posterior gnathopoda with the propodos very narrow, 

 oblong linear, upper edge jn-ovided with unusually coarse spiniform bristles, 

 arranged in several transverse rows. Last pair of uropoda in female with 

 the inner ramus shorter than the basal joint of the outer, simple mucroniform, 

 without any lateral denticles. Telson in female oblong quadrangular, scarcely 

 tapei'ing distally, with 2 pairs of dorsal denticles, posterior incision very 

 shallow and broad; in male considerably more elongate, with the posterior 

 incision much naiTower. Body cream-coloured, each segment of the mesosome 

 liaving a small reddish pigmentary speck at the infero-posterior corners. 

 Length of female 7 mm., of male 8 mm. 



Remarks. — I think there can be little doubt that the present form 

 is that described by Sp. Bate as Anonyx Edwardsii. That, however, the 

 species so named by Kroyer is very difPerent and even Iselongs to another 

 genus, viz., Onesimus, was first pointed out by Boeck. But the latter author 

 was certainly wrong in identif}-ing the British form with his Orchompne 

 serratns, and for this reason I found it right in my «Oversigt» to give the 

 species a new name, proposing fur it tliat of 0. Baiei. I am now, liowever, 

 somewhat uncertain whether the species shortly characterised by Norman in 

 his Shetland Report as Anonyx melanophfhalnnis may not be this species, 

 in which case the specific denomination proposed by that author ought to be 

 retained. The species in question is easily known from the other forms of this 

 genus, not only l)y its comparatively small size, but by the less robust form 

 of the bod}', and lij^ the shallow incision of the telson in the female. 

 The pigment of tlie ej'es is in living specimens dark reddish brown 

 (somewhat lighter in j^oung), but becomes in specimens preserved in spirit 

 almost black. 



Occurrence. — I have only met with tliis form in a few localities off 

 the soiith and west coa.st of Norway. In one of these localities (Folgero) it 

 occurred rather plentifully at a depth of 20 — 40 fatlioms among Ascidite iind 

 HydroidiB. 



Distribution. — British Isles, Shetland (?), coast of France (Chevreux). 



9 — Crustacea.
