Remarks. The form described under this name has turned out to 

 be a new species, different from any of the earlier known forms. I propose 

 for it the name of Pontocrates arctic-its. Of course the statements about distri- 

 bution should be transferred to the true P. norvegicus of Boeck (= Kreyera 

 arenaria of Sp. Bate), to be described below.

Body somewhat robust, with the segments very sharply defined along 

 the dorsal line. Cephalon about the length of the first 3 segments of meso- 

 some combined, and evenly convex above, rostrum comparatively short and but 

 slightly curved, lateral corners angular in front. Anterior pairs of coxal 

 plates somewhat irrregular in shape; 1st pair slightly expanded distally and 

 transversely truncated at the tip, without any insinuation of the terminal 

 edge; 2nd pair much narrower than the 1st and tapering to an obtuse point; 

 3rd pair obliquely truncated at the end, the distal edge forming a slight 

 sinuosity; 4th pair much deeper than the preceding pairs, distal edge slightly 

 curved, infero-posteal corners but very little projecting; 5th pair very large 

 and broad. Epimeral plates of metasome much larger in male than in female, 

 and evenly rounded. Eye scarcely protuberant, rounded, with light red pig- 

 ment, without any whitish coating. Superior antennae in female comparatively 

 short, scarcely twice as long as the cephalon, 1st joint of the peduncle a little 

 longer and much thicker than the 2nd, flagellum about the length of the pe- 

 duncle, and composed of 9 articulations; those in male much more strongly 

 built, with the flagellum larger and somewhat thickened, being composed of 

 1 1 articulations, of which the 6 or 7 proximal ones are densely clothed inside with
