a very different position from that in the present form. Another character by 

 which the present species may be easily distinguished from L. coronata Glaus, is 

 the dense fringe of delicate denticles, with which the posterior edges of the caudal 

 segment are ornamented. Moreover the last pair of legs exhibit some well-marked 

 differences. 



Occurrence. I have found this form occasionally at Aalesund, west coast 

 of Norway, as also in the Trondhjem Fjord just beneath steep cliffs, in depths 

 ranging from 6 to 10 fathoms. In habits it exactly agrees with the preced- 

 ing species. 



Distribution. English and Scottish coasts (Brady, Scott).

Specific Characters. Female. Body of the usual form, the anterior divi- 

 sion being considerably compressed, the posterior slightly attenuated. Posterior 

 edges of last segment of metasome and those of urosome fringed throughout with 

 delicate denticles. Anal opercle about as in L. Scotti. Caudal rami short, 

 scarcely longer than they are broad, apical setse strong and very much elongated, 

 the innermost but one almost attaining the length of the whole body. Inner 

 ramus of 2nd pair of legs much elongated, inner proximal spine of terminal joint 

 placed in front of that of the outer edge, the latter occurring behind the middle- 

 Last pair of legs with the distal joint much narrower and more elongated than 

 in any of the other species, inner expansion of proximal joint with a slender 

 smooth spinule inside the base of the terminal seta. 



Colour light yellow, mottled with brown. 



Length of adult female scarcely exceeding 0.80 mm. 



Remarks. This form was at first regarded by Th. Scott as merely a 

 variety of L. coronata Glaus; but subsequently it has been recorded by that 

 author as a distinct species under the above name. It is unquestionably identical 

 with the form described in detail by Dr. Giesbrecht as L. coronata Glaus; and 

 the form observed by Boeck also seems to belong to the same species, to judge 

 from the drawings he has left behind. Indeed, the present form is closely allied to 

 Claus's species, though at once distinguishable from it by the finely denticulated
