Male with the 2nd pair of legs scarcely larger than in female, but 

 having one of the marginal setae of the inner ramus remarkably transformed, 

 consisting of a thickish and somewhat nodulose basal part and a thin apical 

 bristle. 3rd pair of legs with the inner ramus transformed in the usual manner, 

 outer ramus nearly as in the female. Last pair of legs very small, with no ex- 

 pansion inside the proximal joint. 



Colour yellowish. 



Length of adult female 0.50 mm. 



Remarks. This form is nearly allied to the 3 preceding species, but is of 

 smaller size than any of them, and moreover distinguished by its very narrow 

 body, the unusually coarse integuments, and above all by the much more produced 

 caudal rami. 



Occurrence. I have occasionally met with this small species off the south 

 coast of Norway, at Bis0r, Lillesand and Farsund, in moderate depths among 

 algae. A single specimen was also found in a sample taken by Mr. Nordgaard 

 in the Salten Fjord, north of the Arctic Circle. 



Distribution. Polar islands north of Grinnell Land (2nd Fram-Expedition). 



171. Laophonte Nordgaardi, G. 0. Sars, n. sp. 



(PI. CLXXX). 



Specific Characters. Female. Body comparatively short and stout, tapering 

 only slightly behind. Integuments not very coarse. Cephalic segment comparatively 

 large, exceeding in length the 4 succeeding segments combined; rostral projection 

 rather prominent and obtusely pointed at the tip. Urosome much shorter than 

 the anterior division and having the lateral expansions of the segments rather 

 prominent. Caudal rami short, being scarcely twice as long as they are broad, 

 and considerably divergent, apical setas of moderate length. Anterior antennae 

 rather large, but composed of only 6 articulations, the last 2 being confluent; 

 2nd joint much the largest, and without any projection behind. Posterior antennae 

 with the outer ramus normally developed. Posterior maxillipeds very powerful. 

 1st pair of legs with the outer ramus distinctly 3-articulate, and somewhat exceed- 

 ing half the length of the proximal joint of the inner. Natatory legs with the 

 number of setae on both rami somewhat reduced. Last pair of legs with the distal 

 joint comparatively small, narrow oval in form, and provided with only 4 seta?, 

 the apical one much the longest; inner expansion of proximal joint triangular in 

 form, and extending to about the middle of the distal joint, marginal setae 4 in 

 number, all of nearly equal length.
