E. B. Wilson — Pycnogonida of New England. 
second longest; the three following joints are nearly equal, each 
about as long as the three basal joints united; tarsus small, about 
one-fourth the propodus ; the latter is strongly curved and armed 
below with a series of short stout spines; dactylus about half the 
propodus, stout and curved ; auxiliary claws more than half the dac- 
tylus. The entire surface of the legs and body is scabrous with 
numerous pointed hairy tubercles often tipped with spines ; the late- 
ral processes of the body have three or four of these tubercles near 
the exterior margin; the largest are on the basal joints of the legs; 
on the other joints they are much smaller. The legs are throughout 
hairy and most of the hairs are borne on prominent tubercles. Color 
of alcoholic specimens light brown. Length 2*6 millimeters; extent 
8*4 millimeters. 
The egg-masses of a female specimen from Eastport, Maine, con- 
tain embryos recently escaped from the egg (PI. II, fig. 1 g). The 
antennae of these are enormously large and strongly chelate. The 
basal joint bears, at its extremity, on the outer side, a long spine. 
The two remaining appendages consist of two basal joints and a long 
slender acute terminal one, bearing a spine near its middle. The 
body is nearly hemispherical and without trace of segmentation. 
Rudiments of the eyes have appeared. The rostrum is rounded-con- 
ical and much smaller than in the adult. 
This species is very common northward, under stones, at low-water 
mark, and also down to seventeen fathoms. It has been collected at 
Grand Manan; Eastport; Casco Bay, tfcc. A single specimen was 
dredged by the U. S. Fish Commission, off Block Island, Aug. 30, 1874, 
in thirty-four fathoms, mud, which is the most southern locality 
observed. It is usually found on Ascidians, Hydroids, etc., on which 
it is probably parasitic. 
There can be, I think, no doubt of the identity of this form with 
Stimpson’s Zetes spinosa. It differs somewhat from Hodge’s figure 
in the greater length of the abdomen, stouter proboscis, and less size 
of the oculiferous tubercle, though these differences seem scarcely 
sufficient to separate them as distinct species. 
Family III, Pallenid^e. 
Pallene Johnston. 
Body stout. Rostrum short, rounded. Antennte robust, three- 
jointed, chelate. Palpi wanting. Accessory legs nine-jointed, pres- 
ent in both sexes. Legs very long ; dactylus with auxiliary claws.
