of pleonal epimeron 2. It bears little similarity to its sympatric con- 

 gener, M. frequens^ because of numerous maxillipedal and uropodal 

 differences. 



Paraphoxus Sars 

 Paraphoxus oculatus (Sars) 



Phoxns oculatus Sars, 1879, p. 441. 



Paraphoxus oculatus. — Sars, 1895, pp. 149-150, pi. 51. — J. L. Barnard, 1960b, pp. 

 240-243, pis. 27, 28 (with synonymy) ; 1966a, p. 89. 



Materml.— Stations 7229 (1),7231 (2), 7234 (2). 



Distribution. — Apparently occurring throughout the northern 

 hemisphere and recorded from South Africa, 27-2398 m, submerging 

 in low latitudes, not shallower than 239 m in the Californias.

Phoxocephalus kergueleni. — Stebbing, 1906, p. 135. — J. L. Barnard, 1960b, p.

These specimens have the palmar defining tooth of gnathopod 2 

 larger than in other materials reported in the literature and so may re- 

 quire infraspecific designation. Apparently this species is widespread 

 throughout the bathyal of the southern hemisphere and as far north 

 in the Atlantic Ocean as the Caribbean Sea and in the Pacific Ocean 

 as California. The specimens from 7358 lack spines on the rami of 

 uropod 2 but those of 7229 have them, and thus resemble P. homilis 

 J. L. Barnard (1960b), a related species in contiguou shallow water. 

 Phoxocephalus kergueleni is distinguished from P. homilis in the 

 stouter gnathopod 1 and the shape of gnathopod 2. The specimens 

 from 7229 have the stout first gnathopod but in view of uropod 2 

 might represent hybrids between the two species. All of the speci- 

 mens from 7364 and two of the seven from 7358 lack eyes. 



Material.— Stations 7229 (5), 7231 (1), 7358 (7), 7364 (1). 



Distribution". — Southern hemisphere and midlatitudes of northern 

 hemisphere from 220 m in the subantarctic to 2398 m in midnorth 

 latitudes.
