NO. 1701. NORTHWEST PACIFIC I80P0DS— RICHARDSON. 81 



four pairs of legs are ambulatory and are furnished with a few 

 spines and hairs. 



Nine specimens of this species come from the following localities: 

 Station 4772, on " Bowers Bank," Bering Sea, at lat. 54° 30' 30'' N. ; 

 long. 179° 14' E., and station 4771, at lat. 50° 30' N.; long. 179° 17' 

 E. ; station 4781, on the way from " Petrel Bank," Bering Sea, to 

 McDonald Bay, Agattu Island, Aleutians, by the passage east of 

 Semisopochnoi and Amchitka Islands, at lat. 52° 14' 30" N. ; long. 

 174° 13' E., at a depth of 344-482 fathoms in broken shells, brownish- 

 green sand, and fine gray sand and pebbles. 



This species is very close to ^ga symmetrica Richardson, but 

 differs in the much larger and oval eyes, which are also closer together, 

 in the greater number of articles in the flagellum of both pairs of 

 antenna?, and the longer second antenna?, and in the 

 lesser number of spines on the prehensile legs. 



Type-specimen.— Cat No. 39499, U.S.N.M. 



One specimen from station 4906, 10-20 miles 

 southwest of Koshika Islands, Eastern Sea, at fig. 8.— ^ga syn- 

 Tsurikake Saki Light, S. 85° E., 17.2 miles (lat. 31° 7^'™ "fwo 

 39' N.; long. 129° 20' 30" E.), taken at a depth of segments of 

 369 fathoms, I have doubtfully referred to this ''^'*^^^- ^ ^^■ 

 species. It differs from the other specimens in the less oval eyes, in 

 the shorter second antennae, which extend to the posterior margin of 

 the second thoracic segment, and in the narrower and longer body, 

 being 8^ mm. :20 mm. In color it is reddish brown. 



.ffiGA SYNOPTHALMA, new species. 



This species is very similar to the preceding, but differs in having 

 the eyes confluent and not separated from each other; in having the 

 first antennae, with a flagellum of only 12 articles, extending to the 

 middle of the first thoracic segment; in having the second antenna?, 

 with a flagellum of 16 articles, extending to the middle of the third 

 thoracic segment ; in having the outer post-lateral angles of the first 

 three epimera rounded and not acute ; and in having the distal end of 

 the frontal lamina rounded and not flat, and more circular in outline 

 instead of oval. 



Only one specimen comes from station 5091, in Uraga Strait (en- 

 trance Gulf of Tokyo), at Joga Shima Light; N. 15° W., 4.2 miles 

 (lat. 35° 04' 10" N.; long. 139° 38' 12" E.), at a depth of 197 

 fathoms in green mud and coarse, black sand and pebbles.
