NO. 9 HILTON : PYCNOGONIDS 293 



The next to the last, or 4th, joint bears several strong hairs on its free 

 blunt appendage. The last joint has a fringe of short stout hairs on its 

 inner margins and slightly stronger ones, about 4 in number, at its distal 

 margin. There is a decided bend in the palpi at the 4th joint. The palpi 

 as a whole slope downward, but the bend at the 4th joint prevents them 

 from extending below the tip of the proboscis. 



Ovigers: These are apparently 10-jointed in the male type. The last 

 4 joints are small, and the last 3 are bent back upon the others. The last 

 joint is small, armed with 3 long spines. The next 2 are not clearly 

 marked ; each has 2 short spines. The 4th from the last bears a thick 

 projection almost at right angles to the rest of the segment. This ap- 

 pendage or joint bears several strong hairs. The next joint above is about 

 equal to this in size but bears fewer hairs. Of the other joints, the 1st is 

 short and broad, the 2nd is about the same length but not so broad by 

 half, the 3rd and 4th are about equal, the 5th a little longer than the 4th 

 and bent almost at right angles to it. There are many specimens which 

 have no ovigers, yet seem to be adult. Some, at least, seem to be adult 

 females. 



Color: Light straw, with deeper red-brown where the chitin is thicker. 



Ambulatory legs: The legs seem about equal in length. The 1st 

 coxal joint bears 3 distal projections on its dorsal side. The cephalic joint 

 is the largest and bears about 4 short, sharp hairs. The middle one, which 

 is not quite in the center, is next in size, is conical, and bears a hair at its 

 tip. The most rounded is the smallest, and it bears 2 short hairs. The 2nd 

 joint is about as long as the last but bears no fleshy appendages. There 

 are, however, a number of short, straight hairs along its distal and caudal 

 margin. The 3rd joint is a little narrower and a little longer than the 

 last, with a few lateral hairs in the central part of the caudal margin. 

 The 4th joint is about twice the length of the last, with 2 small groups 

 of small hairs on its cephalic margin and other groups dorsally and 

 caudally disposed. The 5th joint is about like the last, with about 3 rows 

 of hairs on the dorsal surface. The 6th joint is similar with scattered 

 short spines above. The 7th joint or heel is short, with many slender 

 hairs on its lower surface and one large tooth. The last joint is gently 

 curved, bearing a large terminal claw and 2 smaller claws which are less 

 than a third the length of the large claw. The upper side is quite convex 

 and rather free from hairs; the lower side has 3 strong teeth near the 

 heel and a number of more delicate hairs along the whole concave margin. 

 The terminal claw is less than half the length of the terminal joint.
