lobes narrowly rounded at the extremity. 
Colour, as in the preceding species, a uniform greyish-

Occurrence. — Only 2 examples of this form were 
taken on the Norwegian North-Atlantic Expedition, the one 
far out at sea, west of Lofoten (Stat. 248), the other north- 
west of Beeren Eiland (Stat. 312); depth 658 and 778 
fathoms. Both Stations in the cold area.

Specific Character. — Body less thickset, with dorsal 
face uniformly arched and not very large epimera. Head 
but slightly convex above, with frontal plate almost hori- 
zontal. Lateral plates of 3rd abdominal segment produced 
posteriorly to a sharp, upward-bent book. No eyes. An- 
tennas less robust in structure than in the 2 preceding 
species. The 2 anterior pairs of legs with hand regularly 
oval and palmar margin defined posteriorly by a distinct 
projection. Sixth pair of legs less prominently elongate. 
Last pair of legs with basal joint comparatively small, 
and jutting out, posteriorly as a long and sharp dagger- 
shaped projection. Last pair of caudal stylets about as 
in H. abyssi. Telson short, cleft almost to the base. Col- 
our whitish-grey. Length 5 nm . 
Locality. — Stats. 200, 262. 
Remarks. — This small species is easily distinguished 
by the strong, hook-shaped point formed posteriorly by the 
lateral plates of the' 3rd abdominal segment, as also by 
tpe very peculiar form characterizing the basal joint of the 
last pair of legs. 
Description of the Female. — The body (see PI. XID, 
fio . 7) has a relatively more slender form than in the other 
species of the genus, "and is somewhat compressed, though 
with the back round. 
The head is appreciably longer than the 3 anterior 
segments taken together, and but slightly arched above, 
with the frontal plate well-nigh horizontal. 
The 4 anterior pairs of epimera are relatively not 
very large, being scarcely at all higher than the body, and 
bear on”the lower margin a limited number (as a rule 4) 
of ciliated bristles. The 4th pair are obtusely rounded 
posteriorly, below the emargination.
