RemarJcs. — The form described under this name has turned out to

 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 slighth^ 

 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-

 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 (3 or 7 proximal ones are densely clothed inside with
