THE VOYAGE OF H.M.S. CHALLENGER, 
The body and limbs are thinly pubescent, the carapace narrow in proportion to its 
length, with the spines disposed as commonly in specimens of Eurypodius latreillei of the 
same size and sex, e.g., two upon the gastric, one upon the cardiac, one on each branchial 
region and one on the posterior margin, besides some smaller granules on the sides of 
the hepatic and branchial regions. There is a small spine on the upper margin of the 
orbit, besides the postocular spine. The spines of the rostrum considerably exceed half 
the length of the carapace, the spines are contiguous at the base, but in the distal third of 
their length they curve laterally and outward (as shown in the figure) ; there is a strong 
spine on the interantennuiary septum. The eyes, antennae, and maxillipedes are of the 
same form as in Eurypodius latreillei . The chelipedes have, as in young males of the 
typical variety (a) of that species, the palms not turgid, but compressed, the fingers 
acute, without teeth, and without any intramarginal hiatus when closed ; the merus and 
carpus-joints have a few distant granules on their upper margins. The ambulatory legs 
are very imperfect and their dimensions cannot be given, but they were evidently slender 
and considerably elongated, with the penultimate joints larger than the preceding and 
very little dilated.

The example described above (a small male) was dredged off the coast of Chiloe in 
175 fathoms (a much greater depth than any recorded for the true Eurypodius 
latreillei) in lat. 50° 8' 30" S., long. 74° 41' 0" W. (Station 308). It is in a much 
broken condition. 
An immature female, dredged at the same locality and depth, has the rostrum 
scarcely at all reflexed and somewhat shorter, with the spines less divaricate at the apex; 
the chelipedes and ambulatory legs clothed with a denser pubescence ; the latter much 
less elongated. This specimen, although distinguished by the narrower carapace and more 
elongated rostrum, much more nearly resembles the typical Eurypodius latreillei than 
does the male.

Carapace subpyriform, moderately convex, its dorsal surface without spines ; no 
prseocular spine, but distinct supraocular and postocular spines ; rostrum composed of 
two short, acute, slightly divergent spines. Post-abdomen (in the male) distinctly seven- 
jointed. Eyes small and partially retractile. The basal antennal joint is about twice as
