226 ALLAN HANCOCK PACIFK ITIONS VOL. 18 



Uropods stout. Uropod 1 : rami sh< an peduncle, each with a 



marginal and a terminal stout spine, ped ith 2 pairs of stout spines. 



Uropod 2: margin of peduncle with ' t spines, only inner ramus 

 with a stout marginal spine, ends of hot' ram. each with a stout spine. 



Uropod 3: inner ramus about five sixths r.s long as outer, article 2 

 of outer short, about one sixth as long as article 1. 



Telson moderately broad, apices subacute, each with a long and a 

 short lateral, subapical seta. 



Third epimeron: posterior edge nearly straight, scarcely convex, 

 armed with one seta above the slightly produced lower corner. 



Male. — Sexual dimorphism typical. 



Holotype. — AHF No. 539, ovigerous female, 4.2 mm. 



Type locality. — Station 2312-53, off Seal Beach, California, 33-42- 

 06 N, 118-05-22 W, 7.5 fms, brown sandy mud, gravel, May 16, 1953. 



Remarks. — Specimens of this species have been collected in a bay 

 environment at San Quintin Bay, Lower California. They differ from 

 most open ocean members of the species in the evenness of the teeth on 

 peraeopod 5, the slightly narrower hands of the gnathopods and the 

 longer spines of the uropods. Uropod 2 lacks marginal ramal spines. 

 Similar but larger male specimens were collected in plankton off 

 Coronados Islands in which the fifth articles of the gnathopods were 

 longer and narrower than typical. All other criteria of these specimens fit 

 the typical members, including the broad rostrum, the unproduced 

 epistome and the long inner ramus of the female third uropod (in the 

 San Quintin specimens). 



Material examined. — 224 specimens at 39 stations. 



Distribution. — Southern California coastal and insular shelves, 7 to 

 60 fms. Collected once on the west slope of the Santa Cruz Basin at 

 80 fms. A bay form occurs in San Quintin Bay, Lower California. 

 Occasionally caught in dipnets and larvae traps. 



Paraphoxus floridamis (Shoemaker), new combination 



(Plate 21) 



Pontharpinia floridana Shoemaker 1933: 5-8, figs. 3, 4; Shoemaker 

 1948:2. 



Diagnosis of female. — Head with a strongly constricted rostrum 

 which is distally spatulate; eyes moderately large, oval.
