500 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



Diagnosis. — Front with 2 large, triangular teeth ; 2 sharp antero- 

 lateral teeth. Last leg overreaching merus of third ambulatory leg. Lobe 

 at distal extremity of ambulatory meri acute. 



Material examined. — 

 143-34. Wenman Island, 100-150 fms, Jan. 11, 1934, 1 young speci- 

 men (photographed). 



Measurements. — Young specimen: length 5.5 mm, width 6.2 mm. 



Habitat. — Mud and crushed shell (Crane). Velero III records show 

 rock, coral, and nullipore, presumably with sand. 



Depth.— 60-150 fms. 



Remarks. — The single small specimen from deep water north of 

 Wenman Island conforms remarkably with Miss Crane's description of 

 the type, and also with a small specimen from the Gulf of California, 

 particularly as regards the front, the two triangular teeth of which meet 

 at almost a right angle. Extension of the range of C. cortezi to the Galap- 

 agos Islands is less surprising in view of the simultaneous extension of 

 ranges of two other Gulf of California species, C. lucasii Rathbun and 

 C. fragilis Rathbun. 



C. cortezi is now recorded from the Galapagos Islands.

 orbital teeth sharpened. Ambulatory legs wide ; an acute lobe at distal end 

 of mems of legs 1 and 2, that of leg 3 rounded.
