210 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 18 



Material examined. — 435 specimens at 41 stations. 

 Distribution. — Southern California coastal shelf, generally 10 to 24 

 fms, occasionally at 50 fms, and aberrant specimens at 210 fms. 



Paraphoxus daboius, new species 



(Plates 10, 11) 



Diagnosis of female. — Head with tenuous but rather broad rostrum ; 

 eyes very small, in some specimens not visible. 



Epistome produced into a small, acute cusp. 



Maxillipedal palp article 4 apically simple. 



Gnathopod 1 : article 5 much longer than 6, the latter broad, with a 

 transverse palm. Ratios of lengths of articles 5 and 6: Gnathopod 



1 — 30:23, Gnathopod 2 = 27:22. 



Peraeopod 3 : articles 4-5 nearly as wide as article 2, article 6 shorter 

 than 5. Ratio of widths of articles 2, 4, 5, 6 = 30:28:28:12. 



Peraeopod 4: ratio of widths of articles 2, 4, 5, 6 = 42:28:19:7. 



Peraeopod 5 : article 2 nearly as wide as long, the ratio of width to 

 length being 53 :56 ; article 2 extends down nearly to the end of article 

 4, sweep point at middle of article 4, lower edge truncated; posterior 

 edge with 3 small teeth and an occasional minute one proximally ; articles 

 4 and 5 rather stout. 



Uropods 1-2: spines rather stout, each ramus of each uropod with 

 one spine, peduncle of uropod 1 with one marginal spine, of uropod 2 

 with 2 spines. 



Uropod 3: inner ramus less than one third as long as outer; article 



2 of outer less than one third as long as article 1. 



Telson rather slender, apices rounded, lateral notches each with 3 

 long setae. 



Third epimeron: posterior edge convex, lower corner slightly pro- 

 duced, bearing one seta. 



Male. — Eyes not as large as in most species of Paraphoxus, otherwise 

 with typical sexual dimorphism.

Type locality. — Station 2227-53, east of Santa Catalina Island, 

 33-24-12 N, 118-20-01 W, 128 fms, fine dark green mud, Feb. 28, 1953. 



Remarks. — This species is related closely to P. lucubrans n. sp. but 

 differs in the following ways: (1) the eyes of the female are much 

 smaller; (2) the spination on uropods 1-2 is less abundant; (3) the
