Family PHOXOCEPHALIDAE 



Coxophoxus, new genus 



Diagnosis: Article 2 of pereopod 3 slender, scarcely wider than ar- 

 ticle 3; palp of maxilla 1 uniarticulate; flagellum of antenna 2 multi- 

 articulate; gnathopods enlarged, first smaller than second; body of 

 mandible lacking large process at juncture of palp, molar large, with 

 ridged triturating surface; palp article 4 of maxilliped bearing large 

 apical spine or spines, palp article 3 not produced ; eyes present ; antenna 

 2 lacking basal ensiform process; anteroventral corner of head unpro- 

 duced ; dorsoposterior edge of coxa 4 not excavate. 



Type species : Coxophoxus hidalgo, new species. 



Relationship: This genus combines characters of the genera Phoxo- 

 cephalus Stebbing and Proharpinia Schellenberg. It differs from Phoxo- 

 cephalus in the slender second article of pereopod 3 and from Pro- 

 harpinia in the uniarticulate palp of the first maxilla and the unpro- 

 duced cephalic corner. 



Other species assigned: Phoxocephalus coxalis K. H. Barnard 

 (1932). 



Coxophoxus hidalgo, new species 



(Figs. 37, 38) 



Diagnosis: Article 2 of pereopod 5 hugely expanded, more than 90 

 percent as wide as long. 



Description: The figures presented herein show the other features. 

 The male has the enlarged eyes typical of many phoxocephalids and an 

 elongated inner ramus of the third uropod. The distolateral surface of 

 article 1 on antenna 1 has a process. 



Holotype: AHF No. 5810, male, 4.0 mm. 



Type locality: Station 5943, East Cortes Basin, California, 32°- 

 16'-30"N, 118°-27'-55" W, 1675 m, November 10, 1958. 



Basin material: 6 specimens from the type locality. 



Relationship: This species differs from Phoxocephalus coxalis K. H. 

 Barnard (1932), which I assign to this genus, by the much more 

 broadly expanded second article of pereopod 5. In C. coxalis the article 

 is only about 70 percent as broad as long.
