312 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 18 



Proharpinia tropicana, new species 



(Plate 55) 



Diagnosis. — Third pleonal epimeron with a slight notch at the 

 lower posterior corner; article 2 of peraeopod 5 with about 3 medium 

 sized teeth; telson with blunt spinose apices; eyes medium in size, 

 rectangular; uropod 1 with very short outer ramus. 



Descriptive features. — Head tall, nearly carinate at top, lower head 

 process small ; maxilliped similar to Heterophoxus oculatus, inner plate, 

 with one medial spine and 2 apical setae; gnathopods 1 and 2 similar; 

 rami of uropods naked ; last three peraeopods very slender. 



Holotype.—USNM No. 97309, female, 2.5 mm. 



Type locality — Station 169-34, Academy Bay, Indefatigable Island, 

 Galapagos Islands, 00-46-18 S, 90-19-27 W, 15-25 fms, sand, rock, 

 algae, Jan. 20, 1934, collected by the Velero III. 



Remarks. — It is unfortunate that only one specimen of this species 

 exists but the distinctive third pleonal epimeron and short outer ramus 

 of uropod 1 render it easily recognizable. 



Distribution. — Galapagos Islands. 



Proharpinia antipoda Schellenberg 



(Plate 56) 



Proharpinia antipoda Schellenberg 1931 : 80-81, fig. 41. 



Diagnosis. — Tooth of third pleonal epimeron very long and curved 

 upwards; article 2 of peraeopod 5 cut into about 5-7 large teeth, telson 

 with apices acutely pointed, each with one slender seta; eyes rather 

 small in female; uropod 1 with outer ramus of normal length; lower 

 process of head large and diverging from axis of rostrum; rami of first 

 2 uropods bear many long spines, on uropod 2 the spines extending 

 nearly to the ends of the rami. 



Material examined. — Swedish State Museum Catalogue Nos. : 2760, 

 Ultima Esperanza (11) ; 2789, Kap Valentyn (1) ; 2798, Ushuaia (8), 

 type ; 3466, Puerto Toro ( 1 ) ; 3467, Puerto Augusta ( 1 female, eyes

 Port Louis, Falkland Islands (1). 



Remarks. — The male specimen from Cat. No. 2760 has the teeth of 

 peraeopod 5, article 2, nearly obliterated but is distinguishable from P. 

 stephenseni by the spines of the second uropodal rami and other char- 

 acters.
