 ami only provided with 5 marginal seta*. Ovisac generally rather large, though 

 cuiitaining a limited number of ova. 



Mali with the inner rainus of 3rd pair of legs transformed in a similar 

 manner to that in the type species. Last pair of legs with the inner expansion 

 of proximal joint scarcely extending as far as the distal joint, and only provided 

 with 2 spiniform setae. 



Colour dark yellowish grey.

l\'<-m<irk*. This form was rather imperfectly described by Claus as a spe- 

 cies of the genus Dactylopus, Boeck justly removed it from that genus, and in- 

 cluded it in his new genus M<:<,rlir<i. Indeed, saving the distinctly 3-articulate 

 inner rainus of the 1st pair of legs, it agrees in all essential characters closely 

 with the type species, 3L Z////V/W///. The Canthocamptus /HUTU* of Scott is un- 

 questionably identical with the present species. 



Occurrence. I have met with this very small form not (infrequently along 

 the whole south and west coast of Norway, at least up to tbe Trondhjem Fjord 

 in moderate depths among algae. It is a strictly marin form, being scarcely ever 

 found in brackish water. In the living state it is readily observed by its dark 

 colour.
