two small lateral appendages. Anterior foot-jaw small, armed with a stout 
curved terminal spine and two marginal setiferous lobes. Posterior foot- 
jaw uncinate, forming a moderately strong prehensile organ, the terminal 
claw slender and strongly curved. The inner branch of the first pair of 
swimming feet elongate, two-jointed, the last joint small, the first nearly 
twice the length of the three-jointed outer branch. A small seta springs 
from the inner margin of the second basal joint, and another from the 
inner margin and near the proximal end of the elongate first joint of the 
inner branch. Two slender hairs, one of which is setiferous, spring from the 
extremity of the last joint. Each of the three joints of the outer branch is 
armed near the exterior distal angle with a short spinous seta ; three hairs 
— two of which are long and setiferous and bent near the middle — spring 
from the extremity of the last joint. The inner branches of the second, 
third, and fourth pairs are one-jointed, that of the fourth rudimentary; 
the outer branches are three-jointed, the joints subequal and more 
strongly setiferous than those of the first pair. Fifth pair foliaceous, — the 
same on the both sides, — one-branched, and furnished with three hairs on 
the outer margin and four on the inner — the upper of the four being 
densely setiferous. The extremity of each branch terminates in a stout 
bluut-pointed spine nearly as long as the branch to which it appears to be 
articulated. Abdomen four-jointed, the first segment composed of two 
coalescent joints, and about twice the length of the next two together, the 
second, third and fourth segments subequal. Caudal stylets fully half as 
long as the last abdominal segment, slightly divergent, each stylet 
furnished with a long geniculated terminal seta and several small 
hairs. 
Male closely resembling the female but smaller (*87 mm). Anterior 
antennae eight-jointed, the two first joints long, as in the female, the fifth 
shorter than any of the other joints, and furnished with an olfactory ap- 
pendage. The antennae are distinctly hinged between the sixth and seventh 
joints, and indistinctly hinged between the third and fourth. The posterior 
antennae, mouth-organs, and first pair of swimming feet as in the female. 
The last joint of the outer branch of the second pair of swimming feet 
like that of the female, but furnished with an additional and moderately 
stout plumose hair, the normal position of which appears to be that shown 
in the figure (fig. 12). A long spiniform appendage springs from the 
basal joint of the third pair, and close to, but inside of, the one-jointed 
inner branch (fig. 14). This appendage is more than twice the length of 
the inner branch, and as long as the two first joints of the outer branch. 
The fifth pair of feet is furnished with fewer marginal hairs than those of 
the female, and the terminal spine seems to be continuous with, and not 
articulated to, the basal part of the foot. Abdomen five-jointed, caudal 
stylets and setae as in the female.

Habitat. — Washed from a large root of sea-weed brought up in the 
trawl-net near the middle of the estuary between Fidra and St Monans 
during February last (1892). This remarkable species is readily dis- 
tinguished by the strong dorsal armature of the body segments. The 
first pair of feet have the basal part long and rather slender. The rostrum
