the other two, is provided with two sete on the inner margin, two spines 
on the outer margin, and also with two long spines of unequal length and 
a long seta at the apex ; the inner branches have the outer edge of each 
joint fringed with minute bristles, and a moderately long seta springs 
from the distal angles of the first and second joints and from the lower 
half of the third joint ; the third joint is also armed with a terminal 
spine and two long terminal sete (pl. xi., fig. 6). 
The armature of third and fourth pairs is similar to that of the second, 
except that there are two sets instead of one on the lower half of the 
inner margin of the last joint of the inner branches (pl. x., fig. 19, and 
ple x1; fic.,.7); 
The fifth pair resembles, to some extent, the same appendages in female 
specimens of Canthocamptus palustris, but the inner portion of the 
primary joints, which are broadly sub-triangular, have the apex more or 
less distinctly truncated rather than rounded. The armature of the inner 
portion of the primary joints consists of five apical sete, of which the 
three inner ones and the outermost are only of moderate length, but the 
other—the second from the outside—is greatly elongated. The secondary 
joints are oblong, with the outer and inner margins nearly parallel, the 
length being equal to about twice the width at the broadest part ; outer 
margin nearly straight, inner slightly convex, apex obliquely truncate and 
furnished with six sete ; the second from the inside is very long, while 
the second from the outside is short ; the others are of varying lengths, as 
shown in the drawing (pl. xi., fig. 8). Furcal joints very short (pl. xi., 
fig. 9). 
Habitat.—West of Dunbar, near low water, collected by hand-net 
Ocober 16, 1894, as well as in a collection from Musselburgh collected 
the same year ; rare. 
Remarks.—Though this species resembles Canthocamptus palustris in 
some respects, the difference in the proportional lengths of the joints of 
the antennules and of the outer and inner branches of the first pair of 
swimming feet, and also in the form of the fifth pair, and especially of the 
secondary joints of that pair, is sufficient to distinguish it. 
Fam. LAOPHONTIDA. 
Genus Laophonte, Philippi (1840). 
Laophonte longiremis, sp. n. Pl. xi., figs, 10-20. 
Description of the Female.—Body slender, and somewhat similar to 
Laophonte thoracica in general appearance. The cephalothoracic segment 
is equal in length to the next three taken together, gibbous on the under 
side, the ventral margins boldly rounded, the depth being nearly equal to 
the length of the segment ; the remaining segment short. Furcal joints 
about equal in length to the last abdominal segment. Length of the 
specimen represented by the drawing (fig. 10) ‘6mm. (about , of an 
inch). 
Antennules long, slender, and composed of seven joints (fig. 11); first 
and second joints subequal, considerably longer than the first, the next 
three small, but the end joint is nearly as long as the combined lengths of 
the three preceding joints, as shown in the formuls :—
