Parapagurus pilosimanus, sp. nov. 
Male. The carapax is divided by the deep cervical suture, which 
is arcuate, — not in the form of a truncated V with irregular sides, as 
in JEupagurus. The anterior portion is slightly broader than long, 
smooth, and almost entirely naked. The anterior margin is more 
nearly straight than in the species of Eupagurus , but projects in a 
well-marked, though broad and obtuse, rostrum, each side of which 
the margin is straight to the lateral margin, except a very slight 
prominence between the bases of the eye-peduncles and antennae. 
The posterior portion of the carapax is but little broader than the 
anterior portion and is only slightly expanded posteriorly. 
The eye-peduncles are slender, taper distally, are scarcely as long 
as half the width of the front of the carapax, and are clothed with 
long hairs along the upper side. The cornea is very small, almost 
wholly terminal, and the pigment black. The ophthalmic scales are 
small, spiniform, slender, and acute. 
The peduncles of the antennuke are very long and slender; the 
proximal segment is about as long as the eye-peduncle ; the second 
and third are nearly cylindrical, though the second is slightly com- 
pressed laterally, smooth, and almost perfectly naked ; the second is 
about as long as the first, and the third fully twice as long. The 
dorsal, or major, flagellum is more than three-fourths as long as the 
distal segment of the peduncle, is composed of about forty segments, 
tapers to a very long and slender tip, and is densely clothed beneath 
with hairs. The inferior, or minor, flagellum is very slender, about 
half as long as the superior, and composed of eight or nine segments. 
The peduncles of the antennae reach to the distal end of the second 
segment in the antennular peduncle, and the segments have pretty 
nearly the same form and proportions as in Eupagurus hernliardus. 
The acicles reach to the tips of the peduncles and are densely hairy 
above, while the rest of the peduncle is smooth and nearly naked. 
There is no tooth or spine at the inner side of the base of the acicle, 
but outside the base there is a prominent dentiform lobe denticulated 
at its extremity. The flagella of the antemne extend far beyond the 
long ambulatory legs, are very slender, smooth, and almost entirely 
naked. 
As seen from without, the inner oral appendages do not differ 
essentially from the corresponding parts in Eupagurus. The three 
or four distal segments of the endognaths of the external maxillipeds 
are, however, more cylindrical and a little more slender than in 
Eupagurus hernhardus.
