336 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 18 



Harpiniopsis galerus, new species 



(Plates 70, 71, 72) 



Diagnosis. — Lower corner of head scarcely produced. 



Epistome not produced. 



Peraeopod 5, article 2 produced down to the end of article 3, pos- 

 terior edge quite variable in configuration (see figures), with 4-8 shal- 

 low teeth. Rest of appendage slender and with normal setation. 



Third pleonal epimeron with moderately large, slightly upturned 

 tooth. Pleon segment 4 bears a posterolateral spine on each side. 



Male. — Antenna 2 as long as body. 



Holotype. — AHF No. 5316, female, 2.5 mm. 



Type locality. — Station 2436-53, 5.5 mi SE of Long Point, Santa 

 Catalina Island, California, 33-20-00 N, 118-18-00 W, 44 fms, sandy 

 mud and clay. 



Remarks. — This species is closely related to H. emeryi n. sp. from 

 which it differs in the shorter tooth of pleon segment 3 and the more 

 numerous and better developed posterior teeth of peraeopod 5. 



Several slight changes occur from juvenile to adult specimens at the 

 2.5 to 3.0 mm length. The spines on uropods 1 and 2 become slightly 

 longer, article 2 of peraeopod 5 becomes slightly broader and the tooth 

 of pleon segment 3 becomes slightly longer. 



At the position where other phoxocephalids bear eyes there is a small 

 accumulation of cellular material beneath the chitin, which might be 

 confused with true ommatideal bundles. 



Material examined. — 65 specimens at 17 stations. 



Distribution. — Southern California slopes, 45 to 300 fms. 



Harpiniopsis naiadis, new species 



(Plate 73) 



Diagnosis. — Lower corner of head with a short, pointed cusp. 



Epistome not produced. 



Peraeopod 5, article 2 produced down to the end of article 3, pos- 

 terior edge with 4 small teeth. 



Third pleonal epimeron with an oblique posterior edge, prolonged 

 to form an acute process at the lower corner. 



Male. — Unknown. 



Holotype.— AHF No. 5317, female, 2.75 mm.
