VOL. 18 



PLATE 65 



Harpiniopsis sanpedroensis, n. sp. Female, 5 mm, Sta. 2S50. 



Figs. A, epistome; B, mandible; C, lower lip; D, maxilla 2; E, palp of 

 maxilliped; F, telson. 



Remarks. — This species is remarkable for the spinosity of the rami 

 of uropods 1 and 2 and resembles Pseudharpinia dentata Schellenberg 

 in this respect. If Pseudharpinia is to be considered a valid genus then 

 H. sanpedroensis probably should be transferred to that genus. 



Harpiniopsis sanpedroensis resembles Harpinia excavata but differs 

 in the fewer and slightly larger posterior teeth of peraeopod 5, article 2. 



Material examined. — The type locality, 2 specimens. 



Harpiniopsis prof undis, new species 

 (Plate 66) 



Diagnosis. — Lower corner of head with a medium-sized process. 



Epistome not produced. 



Peraeopod 5, article 2 produced down to the end of article 4, distal 

 posterior edge oblique and armed with about 8 teeth, which increase in 

 size distally. 



Third pleonal epimera with lower posterior corner strongly pro- 

 duced. 



Male. — Unknown. 



Holotype. — AHF No. 548, female, 4.5 mm, unique. 



Type locality.— Station 2850, west of Catalina Island, 33-14-00 N, 

 118-18-04 W, June 23, 1954, 620 fms, green mud. 



Remarks. — This species appears related to H. tarasovi Bulycheva 

 1936 in the structure of the fifth peraeopod and third pleonal epimera 

 but bears a large lower head process which apparently is not developed 

 in H. tarasovi.
