a point ending in two short, obtuse, papilla-like stylets. The last three abdominal segments 

 are distinct, those of the middle of the body indistinguishable. Seen laterally it is convex 

 flattened beneath. The legs are curved, one quarter as thick as long, rapidly thickening 

 toward the head. Length, .09 ; breadth, .04 inch. A female. It differs from B sguillarum 

 Kathke, and B. Mppolyhs Kr., in its much narrower, more linear body, slenderer leo-s and in 

 the presence of the caudal stylets. The drawing is a rude one, as the specimen 'had un- 

 fortunately dried before it was finished, but the general contour is given accurately.

Asellus grcenlandieus Kroter. 



Specimens agreeing in length with those noticed by Fabricius, Fauna Gronlandica, were

Idotaea marmorata nov. sp. [Pi. VIII., fig. 6.] 



A stout, thick, reddish-brown species, with the surface slightly nodulated and marbled • 

 body rather short; head more transverse and shorter than in 1. nodulosa Kr., not armed 

 with sharp tubercles in front ; anterior edge emarginate, acutely rectangular on the sides 

 with an angulated slight excavation, and a narrow, deep, but small, mesial notch • eyes' 

 large and prominent. Superior antennae of much the same proportions as in I. nodulosa 

 but the joints are thicker. Inferior pair of antennas long and slender; peduncle stout' 

 with the second joint two thirds as long as the third ; tlagellum longer than the pe- 

 duncle, where in I. nodulosa they are considerably shorter; each joint terminating in a thin 

 vermeil of hairs. Segments of the body convex, on the sides distinctly emarginate • the 

 edges of each segment are straight, not convex as in I. nodulosa. Upper surface of the 

 body thick, with short, impressed, broken lines diverging in their general direction from 

 the median line of the body. Abdomen short, thick, mesially very convex; tips truncated 

 with a sinus at the end. Legs stout, hairy. Color purplish, reddish on the edge of the 

 segments, and the limbs are slightly brownish, in the single alcoholic specimen in the 

 Museum of the Society. Length, .70 ; breadth, .28 inch. 



It differs from specimens of I. nodulosa Kr. in its short, thick, convex body bavin- a 

 much more solid, dense crust than any species found southward. The outer edge of 'the
