tin prominent tooth near lower side of palm, margin of palm serrated and denned above by a spine 

 tooth as in the male; perseopods slender and elongate, with basal joints large, oblong, and serrated on 

 posterior margin; posterior margins of abdominal segments produced into teeth, the median one of 

 which is the largest, the median tooth on the fourth segment being largest of all; posterior uropods 



elongated, outer ramus with sides nearly parallel to near the tip and armed on inner side with four 

 or live and on the outer with five or six fascicles of short spines whose length is less than the diameter of 

 the ramus; the median one of the group of terminal spines is much stouter than the others; inner 

 ramus minute; each lobe of telson terminating in an acute point, on inner side of which is a large and 

 a small spine and on outer a spine or seta. 



Length, 16 mm. 



This species is extensively distributed in the Arctic Ocean, extending down the eastern side of 

 the Atlantic alonga large portion of the coast of Norway and on the western side to Buzzards Bay, and 

 perhaps farther. Several specimens were dredged by the Fish Haul: in Rhode Island waters. In 

 some specimens the spines ..n the posterior uropods are larger than in the one figured. The depth 

 range of this species, according to Sars, is from 10 to 15 fathoms. 



Melita nitida Smith. 



Body slender, compressed; eyes small and round; first antennae two-thirds the length of body or 

 more; second joint of peduncle longer than first and nearly twice the length of third; flagellum 

 longer than peduncle; secondary flagellum three-jointed in adults, not longer than third joint of 



Melita nitida. Woods Sole. 



peduncle; second antenna 5 shorter than first, last joint of peduncle nearly as long as preceding joint; 

 flagellum shorter than peduncle, joints furnished with whorls of long seta-, like those on last joint of 

 peduncle; first four coxal plates deeper than their segments, first three oblong; first gnathopods much 

 alike in the two sexes; carpus longer and broader than the hand, which is oblong, somewhat curved 

 backward; palm about one-third the length of the nearly transverse distal margin of the hand; finger 

 short, much curved, very thick at base, and articulated in the middle of distal margin of hand; hand 

 of second gnathopods in male large, oval, palm evenly convex, about as long as posterior margin above 

 it, with which it forms an almost continuous curve; tip of finger closing against inner side of hand; 

 hand of second gnathopods of female much like that of male, but smaller in size; basal joints of last 

 three perseopods large, oblong, armed with short spines in front and serrated behind; posterior margins 

 of abdominal segments not dentate nor produced; fifth segment with several spines on posterior mar- 

 gin on either side of mid-dorsal line; last uropods long; inner ramus minute, situated in a sinus of 

 peduncle; outer ramus of much the same form as in the preceding species and armed on either side
