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; chele 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: ¢.1 short, squarish; c.2 nearly double ¢.1, swollen on 
the ventral side, where genital pore is situated on posterior pairs; ¢.3 
slightly longer than ¢.1; # about as long as coxal region, stout; 71 some- 
what shorter than £; 4.2 equals 41; ¢s.1 very short, irregularly triangular 
or squarish, with a few small spines on the ventro-distal corner; 45.2 over 
half as long as 42, 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 (pl. xxv, fig. 4), in which are 
some 10 or 11 small spines; c¢/. equals about three-fourths of ¢s.2, nearly 
straight, inner margin slightly convex at middle; awx. c/. 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 1 mm.; first leg about 3.5 mm.; extent 7.5 mm,
