Remarks. This is the only species as yet known of the present genus. 

 2 other forms have certainly been referred to the same genus; but one of 

 these, C. fairliensis Scott, has recently been raised by that author to the type 

 of a new genus, D'Arcytliompsonia, and the other C. minor Scott, is undoubtedly 

 referable to the next genus to be treated of below. 



Occurrence. Some few specimens of this peculiar Copepod were taken 

 last summer at Korshavn, near Lindesnaes, the southernmost point of Norway. 

 The specimens occurred in a depth of about 20 fathoms on a bottom covered 

 with muddy sand. 



Distribution. British Isles (Brady). 



Gen. 72. StenOCarlS, Gr. 0. Sars, n. 



Generic Characters. Body of a slender narrow form similar to that 

 in the preceding genus, but with the integuments rather thin and without any 

 visible sculpturing. Rostrum well defined at the base. Genital segment in female 

 scarcely subdivided. Caudal rami comparatively larger than in Cylindropsyllus. 

 Anterior antennae resembling in structure those in that genus. Posterior an- 

 tennae, however, with the outer ramus less rudimentary. Mandibular palp distinctly 

 biarticulate. Posterior maxillipeds normally developed, terminating in a clawed 

 hand. Inner ramus of 1st and 4th pairs of legs biarticulate, that of 2nd and 

 3rd pairs (in female) uniarticulate; 4th pair, as in Cylindropsyllus. larger than 

 the others. 2nd pair of legs in male with both rami conspicuously trans- 

 formed, 3rd pair with the inner ramus of comparatively simple structure. Last 

 pair of legs more fully developed than in Cylindropsyllus, each armed inside with 

 a strong spine, wanting, however, in male. 2 ovisacs present in female. 



Remarks. This new genus is closely allied to Cylindropsyllus, though 

 differing rather materially in some particulars, and more especially in the 

 altogether normal development of the posterior maxillipeds. The Cylindropsyllm 

 minor of Scott is undoubtedly referable to the present genus.

Specific Characters. Female. Body very slender and narrow, cylindrical 

 in form, though a little thickened in the genital region. Rostrum small, trian-
