of the seo-ments of the body, and by the rather large and somewhat foliaceous fifth pair of 



feet of the female. 



This species appears to be generally distributed along the coasts of Western Europe. 

 It has also been recorded from the Gulf of Guinea, and from the coast of Ceylon. 



Note. Sars 1909(0) has now restored Brady & Robertson's genus Orlhopsyllus for the reception of this Copepod.

Female — length .57 mm. 



Seen from the side, the body appears elongate, cylindrical and considerably arched in 

 preserved specimens. The various segments are well defined. The cephalic segment is of mode- 

 rate size and is nearly as long as the combined length of the first three thoracic segments. 

 The rostrum is short, stout, and slightly recurved. 



The abdomen is composed of four segments. The genital segment is moderately large 

 and rather inflated. It is marked by a well defined suture and is as long as the combined 

 length of the second and third segments. The second and third segments are sub-equal in length. 

 The anal segment is short. The anal operculum is moderately wide and the free margin is 

 boldly rounded. The furcal joints are long and slender. Each joint is fully twice the length of 

 the anal segment, and is furnished with two short outer marginal setae and one inner marginal 

 seta. The apex bears a moderately long spine and one small seta. The proximal end of the 

 joints is somewhat inflated (Plate LX, fig. 16) 



The antennules are short and five-jointed. The fourth joint is shorter than the others 

 and is furnished with a stout sensory filament. 



The exopodite of the antennae is small and one-jointed. It is furnished with one inner 

 marginal seta and one apical seta (Plate LX. fig. 10). 



The mandible palp is short and one-jointed (Plate LX, fig. 1 1). 



The second joint of the second pair of maxillipedes is elongate ovate in outline. The 

 terminal claw is rather shorter than the second joint (Plate LX, fig. 12). 



The exopodites of the four pairs of feet are three-jointed. The endopodites are two- 

 jointed and are shorter than the exopodites. The apex of the second joint of the endopodite 

 of the first pair of feet is furnished with two short stout spines and one seta (Plate LX, fig. 13). 

 The fifth pair of feet is comparatively small. The proximal joint is expanded internally. 

 The apex of the expansion is furnished with one stout spine and two rather strong setae. 

 The distal joint is short and broad. The apex is furnished with four setae. The three outer 

 setae are short. The innermost seta is very long (Plate LX, fig. 15). 

 Male unknown. 



This species can be distinguished from the other members of the genus by the short T 

 five-jointed antennules, by the shape and armature of the fifth pair of feet, and by the rather 

 long furcal joints. 



O c cu r re nee. — One specimen was obtained from the plankton collected at Station 40» 

 off Pulu Kawassang, Paternoster Islands.
