Characters.— Eostrum long, obliquely erect; posterior margin with one tooth 

 near the middle; anterior margin with one tooth near the tip, and at base a long 

 curved spine. Carapace with a median carina unequally four-toothed; sides 

 carinated in such a way as to form irregular quadrangular spaces, with spines 

 at most of the angles; on the anterior margin there is a spine at the outer angle 

 of the orbit and another at the anterolateral angle. First pair of legs about as 

 long as the maxillipeds; upper margin of merus terminates distally in a tooth; 

 hands narrow, elongate, about four times as long as wide; digital spine very long 

 and slender, directed in an obliquely longitudinal direction; anterior margin 

 more longitudinal than transverse. Third pair of legs (the second are lacking) 

 very slender, barely reaching to end of first pair; fourth and fifth pairs of about 

 equal length and slightly exceeding first pair in length. Abdomen carinate behind 

 second segment, carina of third being especially high; on sixth segment and 

 telson it is medially suleate; abdominal pleura of male much more spiniform than 

 in female. 



Dimensions. — Type: length 45 mm. 



Type Locality. — Puget Sound. 



Distribution. — Port Etches, Alaska, to off La Jolla, California; Japan (Balss). 



Remarks. — -Heretofore P. echinata had not been definitely recorded south of 

 Puget Sound. In the "Albatross" collections, however, there are three specimens 

 which had been taken off the Californian coast ; two, an ovigerous female and an
