Harpiniopsis similis Stephensen 



Harpiniopsis similis Stephensen 1925: 171-172, fig. 51 J Stephensen 



1940: 27. 

 Harpinia {Harpiniopsis) similis, Gurjanova 1936a: 150; Gorbunov 



1946: 43; Gurjanova 1951: 372-373, fig. 222. 



Distribution. — Polar Basin; New Siberian Sea; Kara Sea; Norweg- 

 ian Sea; west of Greenland. Depth, 57 to 1090 meters. 



Harpiniopsis fulgens, new species 

 (Plates 67, 68) 



Diagnosis. — Head rather short, strongly and acutely produced at 

 lower corner. 



Epistome not produced. 



Peraeopod 5 with article 2 produced down to the end of article 3, 

 posterior edge with 5-6 shallow teeth on the distal edge only. Rest of 

 appendage normally setose. 



Third pleonal epimeron: posterior edge straight, then prolonged into 

 a large blunt process. 



Male. — Antenna 2 as long as body. 



Holotype.—AHF No. 5315, female, 3.75 mm. 



Type locality. — Station 2306-53, 6.2 mi S. of Pt. Fermin Light, 

 California, 33-36-07 N, 118-18-00 W, April 25, 1953, 215 fms, clay 

 and mud. 



Remarks. — The prolongation of the third pleonal epimera is greater 

 in some specimens of the species, so that it approaches the condition of 

 a definite tooth. In this respect these specimens approach the configura- 

 tion of H. similis Stephensen (1925) and the species may not be specifi- 

 cally distinct from that one. However, variability studies and further 

 morphologic description are needed for the Atlantic H. similis. 



Some specimens bear a slight dorsal head crest. 



Material examined. — 90 specimens at 34 stations. 



Distribution. — Southern California slopes, 70 to 277 fms. Ridge 

 between San Nicolas Island and Santa Cruz Basin, 200 fms. Slope of 

 Santa Catalina Basin, 517 fms. San Clemente Basin, 1092 fms.
