3-articulate, and exceeding half the length of the 1st joint of the inner, the latter 

 about the length of the basal part, terminal claw very slender. Natatory legs 

 well developed, with the inner ram us larger and broader than in most other 

 species, its proximal joint only in the 4th pair setiferous. Last pair of legs com- 

 paratively small, distal joint narrow oval in form, with the inner edge straight; 

 inner expansion of proximal joint short and broad, with 5 marginal setae, the 

 apical one the longest. 



Male with the inner ramus of 3rd pair of legs transformed in the usual 

 manner. Last pair of legs very small, distal joint well defined and somewhat 

 widening towards the end, with 4 marginal setas; inner expansion of proximal 

 joint almost obsolete. 



Body in female of whitish colour, with 3 light orange transversal bands, 

 the 1st across the cephalic segment, the 2nd occupying the posterior part of the 

 genital segment, the 3rd the anal segment. 



Length of adult female 0.73 mm. 



Remarks. This form, first recorded under the above name by Boeck, is 

 a very distinct species, easily distinguished by its slender form of body, the greatly 

 prominent rostral projection, and the long and narrow caudal rami. In the living 

 state it is also readily recognized by its peculiar and beautiful colouring. 



Occurrence. I have met with this form occasionally off the west coast of 

 Norway, as also in the Trondhjem Fjord, in moderate depths among

Specific Characters. Female. Body rather slender, with the segments of 

 the anterior division not very sharply marked off from each other. Cephalic seg- 

 ment of moderate size, with the rostral projection short and broad, obtusely rounded 

 at the tip. Urosome almost as long as the anterior division, lateral expansions 

 of the segments not much prominent, last segment shorter than the preceding one. 

 Caudal rami rather produced, exceeding in length the anal segment, and scarcely 

 at all divergent, apical seta3 much elongated. Anterior antennae rather slender, 

 almost attaining the length of the cephalic segment, and only composed of 6 ar-
