ably deeper than their segments, the first three with a small but conspicuous denticle at the postero 

 interior angle; first ami .second gnathopods of not very unequal size (the first a little smaller), and i l 

 similar form; meruswithaspiniform projection at the postero-inferior 

 angle; carpus subtriangular with a posterior setose lobe which is more 

 prominent in the second gnathopod than in the lirst; hand much 

 larger than the three preceding joints, oblong-oval in outline, palm 

 evenly curved; margin laminate and furnished with a short tooth. 

 or spine, near the middle, and two fascicles of stout spines, one be- 

 hind the other, at distal end; dactyl evenly tapering, smooth within, 

 and furnished with two or three set;e near tip; when closed, the 

 dactyl tits between the spines of the distal end of the palm; three 

 posterior perseopods with basal joint large, oval, and serrated on pos- 

 terior margin; postero-inferior angle of merus produced strongly 

 downward; postero-lateral angles of third abdominal segment with 

 a small, somewhat upturned tooth, a short distance above which is 

 a convexity of the posterior margin; uropods rather slender, last 

 pair with inner ramus nearly twice as long as outer; telson nearly twice as long as wide and distally 

 rounded.

Greenland, Iceland, Spitzbergen, Norway (Sars). 



A single imperfect specimen was examined, which was taken by Hyatt and Van Yleck from 

 Eastport, Me. It agrees perfectly with the description and figures of this species in Sars' Crustacea 

 of Norway, except that the lateral lobes of the head are rounded instead of acute.

Epimeria loricata Sars. 

 Epimeria cornigera Wrrill (not Fahricius). 



Head produced into a long rostrum which is rounded above and curved downward; eves nearly 

 round, protruding; antero-lateral angle of head produced and acute; first antenme shorter than second 

 first joint of peduncle wide, longer than next two; flagellum over twice length of peduncle; second 

 antennae scarcely half length of body; last joint of peduncle two-thirds length of preceding one; 

 thoracic segments with a median crest which becomes higher posteriorly, and is continued upon first 

 four segments of abdomen, posterior ends of crest of each segment becoming successively more acute 

 toward posterior end of body; two rows of tubercles on either side of median crest extending from the 

 first thoracic to third abdominal segment; in lower row but one tubercle to each segment, and in the 

 upper row one tubercle to each thoracic segment, but three upon each of first three segments of abdo- 

 men; coxal plates very large, first three narrow, acute below, antero-lateral angle of fourth and 

 postero-lateral angle of fifth coxal plates strongly produced, acute, and bent outward; first two gnath- 

 opods similar in size and shape; hand oblong, small, palm only slightly oblique; third and fourth 

 peneopods with basal joints deeply excavated behind, forming grooves with sharp margins- tilth 

 perceopods shorter than fourth, basal joint laminately expanded behind, narrowing in distal half; 



uropods with flattened subequal lanceolate rami 

 which are larger than peduncles; telson broad, 

 w ith a triangular notch at tip. 

 Length, 30 mm. 



Arctic regions and North Atlantic Ocean; 

 New England, off Head Harbor, 50 fathoms. 



Acanthozone cuspidata (Lepechin). 



Body covered with numerous large spines. 

 On the thorax the spines are arranged in five 

 rows, one median dorsal row of very largespines, 

 a lateral row of large nearly horizontal spines on 

 either margin, and a row between these and the 

 median dorsal spines; lirst thoracic segment with a large spine projecting nearly horizontally over the 

 first three abdominal segments with a very large median spine and several spines on either
