legs, as usual, very small, but with the distal joint well defined, and having the 

 same number of setae as in the female; inner expansion of proximal joint very 

 slight, with a single seta only. 



Colour yellowish. 



Length of adult female 0.54 mm. 



Remarks. I think I am right in identifying the present form with Cleta 

 brevirostris of Glaus. It was at first very imperfectly characterised by that author, 

 and for this reason Mr. A. Scott did not recognise the species, but described it 

 under another name, viz., L. Herdmani. In his account of the Copepoda of Nice, 

 Glaus gives, however, 2 detail-figures, which do not seem to leave any doubt as to 

 the identity of his form with the present species. The peculiar short spatulate 

 form of the distal joint of the last pair of legs in the female will suffice for 

 distinguishing this form from any of the other species. 



Occurrence. I have met with this form not infrequently off both the south 

 and west coasts of Norway in moderate depths among algae. 



Distribution. British Isles (Scott), Mediterranean, at Messina and Nice 

 (Glaus), the Eed Sea (A. Scott).

. Specific Characters. Female. Very like the preceding species (L. brevi- 

 rostrin). but somewhat more strongly built, with rather coarse integuments. Rostral 

 projection more prominent, with the tip distinctly bilobular. Urosome with the 

 lateral expansions of the segments well defined and densely fringed with spinules. 

 Caudal rami about the length of the anal segment, and of uniform width throughout, 

 both edges fringed with short hairs. Anterior antennae distinctly 7-articulate, the 

 last 2 joints being well defined, 2nd joint without any projection behind, and 

 scarcely longer than the 3rd. Posterior antennae, oral parts and legs of a struc- 

 ture very similar to that in L. breiirostris. Last pair of legs, however, slightly 

 different in shape, distal joint comparatively narrower, rounded oval in form (not 

 transversely truncated at the tip); inner expansion of proximal joint shorter, 

 scarcely extending beyond the middle of the distal joint. 



Male with the inner ramus of 2nd pair of legs transformed in a manner 

 inalogous to that in L. brevirostris, distal seta of inner edge, however, more fully 

 leveloped, with the thickened proximal part very large and coarsely spinulose in 

 its outer half. 3rd pair of legs resembling in structure those in L. breuirottru, 



34 Crustacea.
