of 7 well-defined joints, 2nd joint much the largest, and produced outside to a 

 short triangular projection. Posterior antennae and oral parts normally developed. 

 1st pair of legs comparatively large, with the inner ramus much produced, outer 

 ramus however very small, scarcely exceeding in length l /?, of the proximal joint 

 of the inner, and composed of only 2 joints. The 3 succeeding pairs of legs 

 resembling in structure those in L. brevirostris, but comparatively less slender and 

 with the seta? of the outer ramus somewhat reduced in number. Last pair of 

 legs likewise resembling in shape those in the said species, distal joint however 

 less broad and provided with only 4 setae on the obtusely truncated extremity; 

 inner expansion of proximal joint less produced, extending scarcely beyond the 

 middle of the distal joint. 



Male differing from the female in a very similar manner to that found 

 in the male of L. bremrostris. 



Colour yellowish. 



Length of adult female 0.48 mm. 



Remarks. This form is nearly allied to L. brevirostris (Glaus), but is of 

 much smaller size, and moreover differs in the comparatively shorter, but distinctly 

 7-articulate anterior antenna? and in the very small biarticulate outer ramus of 

 the 1st pair of legs. It also exhibits some slight differences in the structure of 

 the other legs. 



Occurrence. I have hitherto only noted this form from a single locality, 

 viz., Skutesnes, at the southern end of Karm0, S.W. coast of Norway. It occurred 

 here not infrequently in a depth of about 10 fathoms, on a muddy bottom covered 

 with decaying algae. 



Add also the following genus: 



Pseudolaophonte, A. Scott. 



Syn. Laophontina Norm. & Scott. 



Generic Characters. General form of body resembling that in Laophonte. 

 Rostral plate short and broad. Caudal rami somewhat produced. Anterior an- 

 tennse strongly built, especially in the male, and having the number of joints 

 reduced, 2nd joint produced outside to a strong recurved unguiform process. 

 Posterior antennae, oral parts, and 1st and last pairs of legs built on the same 

 type as in Laophonte. Legs of 2nd to 4th pairs, however, rudimentary, and 

 quite unfit for swimming.
