ALLAN HANCOCK PACIFIC EXPEDITIONS 



VOL. 18 



Telson broad, the broad apices each with 3 long spines. 



Third epimeron: ppsterior edge straight, lower corner quadrate, the 

 posterior edge with about. 5 stiff setae. 



, Male. — Sexual dimorphism typical. 

 | Holotype. — AHF No. 5310, female, ovigerous, 3.75 mm. 

 H- Type locality. — Station 2292-53, off Huntington Beach, California, 

 33-35-30 N, 118-05-30 W, 60 fms, fine mud, Apr. 24, 1953. 



Re?narks. — This species cannot be distinguished clearly from P. 

 simplex (Gurjanova 1938: 272) due to the fact that the epistome and 

 third epimera have not been described. 



PLATE 23 

 Paraphoxus similis, n. sp., female, 4 mm, Friday Harbor, Washington. 



Figs. A,B, head; C, epistome; D, peraeopod 5; E, pleon segments 1-3; 

 F,G,H, uropods 1, 2, 3 ; I, telson. 



Some small differences applicable to the new species and of sub- 

 specific value are: 



( 1 ) article 4 of gnathopod 2 is not produced. 



(2) The posterior edge of article 2 of peraeopod 5 is more oblique 

 and the whole article less quadrangular. 



(3) the inner ramus of the feminine third uropod is somewhat 

 shorter. 



(4) the telson has more apical spines. 



(5) the third peraeopod appears slightly shorter and stouter. 



This species is closely related to P. cognatus n. sp., differing princi- 

 pally from it in the massive epistome. In P. cognatus the epistome is 

 produced but is smaller and more sharply pointed. Other minor differ- 

 ences of P. cognatus include : ( 1 ) the rounded lower posterior corner of 

 the third epimeron; (2) the shorter, denser spines on the peduncle of
