E. B. TT7foo;i — Pycnogonida of New England. 
23 
Legs comparatively stout, often distended with the generative 
organs ; first and third joints about as long as broad ; second longer, 
somewhat clavate, longer in the female than in the male ; the three 
following joints are much longer, the sixth longest; tarsus short, 
half the propodus, which has, below, a series of slender spines ; dac- 
tylus about two-thirds the propodus ; auxiliary claws very small and 
slender, about one-fifth the dactylus. All the appendages are thickly 
covered with coarse hairs, which are most numerous on the outer 
joints. The body is slightly hairy or nearly naked. Color light dull 
yellow. Adult specimens are very frequently covered with rubbish, 
and living Bryozoa, Sponges, Rhizopods, etc., are often attached to 
them. Length 12 millimeters; extent 73 millimeters. 
This species has not before been recorded from our coast, though 
taken in great numbers off Halifax by the L T . S. Fish Commission in 
1877. It occurs on rocky, gravelly or muddy bottoms, down to 50 
fathoms. Sept. 24th, 1877, several hauls made off Halifax in 50 fath- 
oms, muddy bottom, brought them up by hundreds, clinging to the 
meshes of the trawl-net. A single specimen was dredged off Salem, 
Mass., in 48 fathoms, soft mud. Many of the specimens had egg- 
masses. In some of these, young were found in various stages of 
growth. In the earliest stage observed (Plate VI, figures 2 i, 2 j) the 
body is very large and swollen, without a trace of segmentation. The 
rostrum is short and directed downward. The five anterior pairs of 
appendages are developed, the posterior one rudimentary. The basal 
joint of the antenna bears a long flagellum. 
The specimens agree well with Bell’s figures and description, and 
are doubtless identical with the form described by him. Whether 
the latter is distinct from the Nymp>hon hirtum of Chr. Fabricus 
cannot be determined without direct comparison with Norwegian 
specimens. The species described by Kroyer as Nymphon hirtum?, 
and figured in the Yoy. en Scand., Laponie, etc., differs materially 
from the specimens examined by me, in the form of the antenna*, 
size of the auxiliary claws, proportions of the palpal joints, and in 
other respects. This form was from Iceland, and is probably identical 
with Fabricius’ species from the “ Norwegian Ocean.” It seems 
advisable to retain, for the present, the name hirtipes for the present 
species until it shall have been proved identical with N. hirtum 
by comparison with European specimens.
