PYCNOGONIDS 267 
what from the inner side of the first. Both joints unarmed, except as 
noted above. 
Palpi 8-jointed, longer than proboscis: 7.1 short and broad, and apt 
not to be seen when the animal is viewed from above; 7.2 much longer 
and more slender, enlarging somewhat distally ; 7.3 short and small; 7.4 
about equal to 7.2; 77.5 to 8 small, rounded, rather densely armed on 
the ventral side with strong bristles; the preceding joints with only 2 or 
3 bristles. 
Ovigera of female about as long as palpi: 7.1 short, broad, longer on 
inner side; 7.2 longer, arising well down on the outer side of 7.1, triangu- 
lar, broad at the distal end; 7.3 equals 7.1; 7.4 somewhat longer, about 
equals 7.2; 7.5 equals 7.4, broader; 77. 6, 7, 8, 9, 10 are usually turned 
back on the basal joints so that the appendage forms a simple hook; the 
diameter gradually decreases from 7.5 to 7.10; 77.6, 7, 8 rounded; 7.9 
longer; 7.10 very small and not always very distinctly marked off. The 
tenth joint is armed with 2 feather-like denticulate spines; there are 
apparently! 2 also on each/.g and 7.8, while there is at least 1 on 7.7. 
Joint 9 has a strong, straight, backwardly pointing spine on the dorsal 
side; on the other distal joints there are a few short, simple spines; 
the proximal part is unarmed. Oviger of male about twice the size of 
that of the female; the general form of the joints much the same, except 
that they are much longer in proportion to the width; arrangement of 
denticulate spines about as in female; corresponding long spine on back 
of 7.9; but 77.4 to 8 have quite a number of long slender bristles, which 
are especially abundant on the outer side of 7.6. There is also a row of 
some 8 or g short, stout, recurved spines on the side of 7.5, while the 
proximal joints of the oviger have more of a tendency to be hairy than 
in the female. Terminal part of oviger strongly incurved. 
Ova were observed in the femoral joint of the female, but no external 
egg-masses were found. 
Legs comparatively rather stout, appearing especially so in the female, 
where the femoral joint is very broad. First coxal joint short, with a 
long, slender dorsal protuberance; ¢.2 only a little longer than ¢.1; ¢.3 
equals ¢.1; f, 4.1, and 4.2 each about equal in length to coxal region; / 
has at its dorsodistal corner a conical protuberance with a short spine; 
és.1 small, triangular; ¢s.2 strongly developed, somewhat arched; heel 
not prominent, but there are 3 or 4 strong spines at this place; sole 
with a series of smaller spines, while there is a row of more slender 
1The margins of these spines are so delicate and thin that when they chance to lie 
over or under the appendage on the slide it is exceedingly difficult to distinguish them 
from ordinary simple spines.
