244. BULLETIN OF THE 
conical elevation. The ocelli are very rudimentary, or entirely wanting. The 
rostrum is almost as long as the body and abdomen together. It is somewhat 
cylindrical, more or less swollen a little behind the middle, and also toward the 
tip. In one specimen the rostrum is almost clavate, 
The palpi extend considerably beyond the rostrum ; their joints have, in a 
general way, the same proportions as in the species described below, but the 
eighth (counting ten joints in the palpi) is very short, even globose. 
Accessory legs much as in the other species. The terminal claw, though 
small, is distinct from and movable upon the preceding. The spines of the 
outer joints are of peculiar and characteristic form (Fig. 13), being flattened, 
obliquely truncate, broadest at base and tip, and narrower in the middle. 
They are arranged in several irregular rows along the lower (i. e. concave) sides 
of the 7th to 10th joints. They are longest in the inner rows; in the outer rows 
they become much shorter, and finally quite disappear ; those of the outer rows 
are not truncate at the tip, but evenly rounded, and of a broadly spatulate form. 
Legs long and slender, four times as long as the body (including rostrum and 
abdomen). Fourth joint longest ; tarsus and propodus (7th and 8th) nearly 
equal, former a little longer ; both are simple and unarmed. Dactylus (Fig. 8) 
excessively long and slender, — more so than in any other Pyenogonid known to 
me ; it is much longer than the propodus. Color varying from straw-yellow 
to nearly white.

Body very short and stout, unsegmented ; three anterior pairs of lateral 
processes separated by very small intervals, last pair usually separated from 
the next anterior by a somewhat greater interval. The processes are very short 
and swollen; their length scarcely equals the width of the body; they are con- 
stricted at the base, and separated from the body by a suture. Abdomen very 
small, less than one fourth the body (exclusive of rostrum), of slender pyriform 
shape, obtusely conical towards extremity. 
The rostrum is of great size, its length being about one and a half times that 
of the body, and of peculiar and characteristic form. At the base it is of 
slightly less diameter than that of the body (2.5 mm.) and. continues of the 
same size for about one third its length ; it then suddenly expands to a diame- 
ter of nearly 5 mm. and then gradually tapers toward the tip; the terminal 
portion is cylindrical and about 3.5 mm. in diameter. The rostrum. is articu- 
lated to the body, upon whieh it is somewhat movable. Mouth large, sharply 
triangular.
