Family Eusiridae 



Rhachotropis oculata (Hansen) 



Figures 26-/ 



Rhachotropis oculata. — Stephensen, 1944, pp. 97-98. — Gurjanova, 1951, pp. 712- 

 713, fig. 496. 



Stebbing (1906) stated that the rostrum of this species is small. 

 Although the heads of the specimens at hand resemble Hansen's 

 figure reproduced by Gurjanova (1951), the rostra are long and 

 hidden from lateral view by the first antennae. Article 3 of antenna 

 1 is not as short as or indistinct as that described by Stebbing or 

 figured by Hansen. Small specimens, difficult to separate from R. 

 inflata Sars, may be distinguished by the produced corner of the 

 second pleonal epimeron. 



Material: Hancock Velero stations 1027 (2), 1149 (4), 4753 (1), 

 4772 (1), 4824 (1), 5615 (1), 5760 (1), 6001 (1), 6006 (1). 



Records: Coastal shelf of southern California and Santa Catalina 

 Island, 64-274 m, caught in benthic grabs and dredges, probably 

 a demersal species infrequently collected in benthic closing devices. 



Distribution: North Atlantic and North Pacific Oceans, Bering 

 Sea, Okhotsk Sea, Japan Sea, 20-274 m. These are the southern- 

 most records of this species in the eastern Pacific Ocean. 



Family Gammaridae 



Maera danae (Stimpson) 



Maera danae. — Shoemaker, 1955, pp. 53-54 (with references). — Barnard, 1964b, 



pp. 108-109. 

 Maera loveni. — J. L. Barnard, 1962b, p. 103, fig. 19 (not Bruzelius). 



Material: 6462 (2), 85 m. 



Additional record: 4770 (1), southern California, 33°21' N., 117°34' 

 W., 15 m. 



Remarks: According to Shoemaker (1955) this species lacks an 

 articulated spine at the palmar defining corner of gnathopod 2, but 

 a spine is present on the specimens at hand, yet the second articles 

 of pereopods 3-5 are broad, not slender as in M. loveni, and distinct 

 eyes are present. Regardless of the gnathopodal spine, the specimens 

 are identified as M. danae. 



Distribution: North Atlantic and North Pacific Oceans, in the 

 North Pacific known as far south as San Quintin Bay in shallow water 

 but primarily a subarctic species submerging with depth toward the 

 tropics, rather rare in southern California and usually occurring in 

 depths of about 200 m.
