margin somewhat oblique, and below defined by a project- 
ing corner, armed with a short spine; posterior to this 
corner, the lower margin of the hand is beset with several 
bunches of short bristles. 
The remaining pairs of legs are considerably elongated, 
sparingly furnished with bristles, and have the outer 3 
joints about equal in length. The basal joint of the 3 
posterior pairs is lamelliform-dilated, oval in form, and 
behind indistinctly serrate. 
Of the caudal stylets, the 2 anterior pairs (fig. 1 i ) 
are uniform in structure, with both branches well developed 
and lanceolate. The last pair (fig. 1 k) exhibit, on the 
other hand, a rather deviating appearance. These are alike 
longer and more powerful in structure than any of the 
preceding pairs, and have the inner branch quite rudimen- 
tary, whereas the outer one is prodigiously developed, acu- 
minate at the extremity, and beset along the margins with 
a few short spines. 
The telson (fig. 1 T) is comparatively small and cleft 
to the base, having the lateral lobules somewhat obtusely 
truncate at the extremity, and furnished there with a short 
bristle. 
Colour a uniform white, without the slightest trace 
of pigment.

Occurrence. — Of this species, a number of individu- 
als were taken, on the 1st cruise of the Expedition, in a 
single locality, off the west coast of Spitsbergen (Stat. 353). 
All the specimens collected were found within cavities or 
passages (originally, there is reason to believe, the work 
of a Teredo) in an old piece of wood that came up in the 
dredge from the enormous depth of 1333 fathoms. The 
Station lay in the cold area.
