10 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 27 



dactylus on peraeopod one with several small spines ; large setal spine on 

 merus. First antenna with six segments; few scales on outer margin of 

 first segment. Lateral margin of pleotelson with spines and setae. Max- 

 illipedal palp of five segments ; endite with few sensory spines on upper 

 edge. Mandible with handlike toothed incisor; long molar process. 

 Palp triarticulate, proximal segment with at least three setae; middle 

 with at least six and distal segment with comblike row of setae. At 

 least 10 sensory setae in setal row. Uropods with two minute append- 

 ages. Base of uropod with medially pointing recurved hook. 



Measurements: Holotype male 3.1 mm long. 



Type locality: 6806(2); Santa Cruz Canyon; 221 m; Dec. 22, 

 1959; rocks and coarse green sand. Lat. Zy 56' 06"N, Long. 118° 52' 

 17"W. 



Distribution: Known only from the type locality. 



Affinities: Close to Jacropsis dubia paucispinis Menzies (1951) but 

 longer, thinner and completely without pigment. The eyes are much 

 smaller, and there are six rather than five segments on the first an- 

 tenna. The number of spines and setae along the edge of the pleotelson 

 is less than in /. dubia. J. dubia rarely was found below 90 m.

Materials examined: 678 1(1). 



Distribution: Santa Monica Canyon at 116 m within the depth and
