284 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 5 



Eye tubercle: At the extreme forward end of the 1st trunk segment 

 and projecting upward and a little forward, about as long as the 2nd 

 trunk segment and cylindrical. From the side it is seen to be blunt ended. 

 Eyes nearer the top than the base. 



Proboscis: About as long as the 1st trunk segment. Cylindrical. 



Caudal segment: Moderately long, projecting upward at a sharp 

 angle. More or less cylindrical, tapering to a point, often bulging in the 

 center, notched at the tip. May have 1 to 3 hairs on its sides. 



Chelifori: These extend forward from the extreme front end of 

 the 1st trunk segment. About equal to the 1st segment of the body in 

 length. First joint slender, almost cylindrical, just slightly enlarged at 

 the distal end. Smooth but for a few hairs. Chela long just over the front 

 and bent nearly at right angles with the 1st joint and not half so long, 

 with a few hairs. Fingers slender, curved, sharply pointed, about as long 

 as the palm. Movable finger longer than the other and more strongly 

 curved. 



Oviger: As long as the animal or longer, slender. First joint short, 

 comparatively thick, 2nd joint twice as long, more slender ; these 2 joints 

 extend downward. The 3rd joint bends backward to run nearly parallel 

 with the trunk. It is half again as long as the first 2 joints together and 

 is more slender than the 1st; slightly curved, with the convexity upward. 

 About 1/4 its length from the basal end is a constriction which looks a little 

 like an articulation. Fourth joint is somewhat shorter than the 2nd, 

 slightly curved. Fifth joint shorter, bent back sharply on the 4th; 6th 

 joint very small oval. The 5th and 6th together scarcely equal the 4th. 

 The 3rd, 5th, and 6th have a few short stiff hairs; some on 6th are di- 

 rected backward. Eggs in several globular masses. 



Ambulatory legs: Slender, 2nd pair 2^^ times the total length of the 

 animal. First coxa short, a little longer than broad. Second coxa over 

 twice the size of 1st; at about the center of its dorsal side is a small 

 rounded elevation. In the male the ventral side extends at the distal end 

 into quite a projection with several small bristles, and at the end of this is 

 the genital opening. The female does not have the projection ; its distal 

 end is swollen, and the genital opening is situated on a slight elevation a 

 little back from the tip. Third coxal joint longer than the 1st, and it be- 

 comes larger as it joins the next division. Femur nearly as long as the 

 whole coxal region, often larger in the female. It is produced dorsally at 

 the distal end into a rounded projection with a long slender hair. In the 

 male there is also a process on the femur just beyond the middle on the
