PYCNOGONIDS 287 



about two and one half times as long as second. Lateral processes 

 about as broad as long, a slight protuberance on the dorsal side distally ; 

 the first 3 pairs closely crowded; between the third pair and the 

 fourth, which is directed posteriorly, is a considerable space, about half 

 as wide as the process. First trunk segment projecting forward beyond 

 the base of the proboscis a short distance, producing a thick neck, of 

 moderate length. 



Caudal segment rather long, over half as long as first trunk segment 

 erect, subcylindrical, rounded at apex. 



Eye tubercle about in the middle of the anterior half of the first 

 trunk segment, directed slightly forward, shorter than caudal segment, 

 conical ; eyes at about the middle, large. 



Proboscis issuing from the antero-ventral side of the first segment, as 

 long as first and second trunk segments together, thick (half as long as 

 broad), cylindrical, obtusely truncate, with a circular constriction near the 

 distal end ; ventral border with a projecting angle at the proximal end. 



Chelifori stout, overhanging proboscis ; scape reaching to about even 

 with end of proboscis, slightly clavate ; chelae hanging downward almost 

 vertically, with the movable finger on the outside. Palm slightly swollen ; 

 immovable finger slender, about as long as palm, slightly curved ; mova- 

 ble finger slender, acuminate, arcuate. 



Ovigera? 



Legs rather stout: c.i short, squarish ; c,z nearly double ^.i, swollen on 

 the ventral side, where genital pore is situated on posterior pairs; ^.3 

 slightly longer than c.\ ; /. about as long as coxal region, stout ; f.i some- 

 what shorter than/ ; /.2 equals f.i ; ts.i very short, irregularly triangular 

 or squarish, with a few small spines on the ventro-distal corner; ts.z over 

 half as long as /.2, somewhat arched, with a distinct heel at the base. 

 Heel armed with 2 strong curved spines and 5 or 6 smaller ones ; sole 

 with a thin lamellar chitinous membrane (pi. xxv, fig. 4), in which are 

 some 10 or n small spines; cl. equals about three-fourths of /J.2, nearly 

 straight, inner margin slightly convex at middle ; aux. cl. minute. The 

 femoral and first tibial joints have slender bristles projecting from slight 

 protuberances on the dorsal side and at their distal ends ; /. 2 has a similar 

 bristle a short distance from the distal end. Otherwise the legs are 

 smooth except for a few microscopic hairs, as is the whole body. 



Integument thin and transparent, the light green intestine with its 

 prolongations into the legs showing through very distinctly, making the 

 animal appear of a greenish color. Intestine considerably dilated in 

 femoral joint. Cuticular cavities not so numerous as in related genera. 



Length but slightly over i mm, ; first leg about 3.5 mm. ; extent 7.5 mm.
