propodos not broader than the carpus, tufts of sete on both sides ; dactylos 
long, slightly curved, and acutely pointed, much longer than the palm, 
which is slightly concave and defined by a short stout seta. Second 
gnathopoda with the meros acutely produced at the distal end; carpus 
triangular, more than half as long as the propodos, and as wide distally as 
the propodos; propodos rectangular, with tufts of sete arranged in three 
longitudinal rows, end transverse, dactylos short, curved, and impinging 
against the side of the joint, instead of along the margin. Fifth pleopoda 
with the rami unequal ; sixth with the rami smaller than in the two 
preceding species, not reaching beyond the extremity of the fifth pleopoda, 
and only slightly longer than the peduncle; sete on the upper margin and 
at the end. 
Female.—Differs from the male in having the palm of the first gnatho- 
pod slightly convex, and not defined. Second gnathopod smaller than that 
of the male, resembling that of the female of Paranenia typica, but with the 
palm slightly concave. Length i inch. |

Corophium lendenfeldi, sp. nov. PI. xx., fig. 1, a to e. 
Eye rather large, elliptical, placed on a rounded lobe between the bases 
of the antenne. Antenne subequal; upper with basal joint large, stout, 
about twice as long as broad, second about two-thirds as long as the first 
and half as broad, third about two-thirds as long as the second and more 
slender, flagellum of about nine joints, nearly as long as the last two joints 
of the peduncle, a secondary appendage of two or three joints is also pre- 
sent; sete very few and delicate. Inferior antenne with the second joint 
short, produced inferiorly and anteriorly into a sharp point, third joint 
nearly as broad as long, fourth longer and stouter than the fifth ; flagellum 
nearly as long as the last joint of peduncle, bearing below numerous stout 
sete which become stouter and more curved towards the end. First gna- 
thopod rather short and stout, ischios and meros short, the latter with a 
tuft of sete towards distal end, carpus broader than the propodos and about 
two-thirds as long, thickly fringed with plumose sete on inferior margin ; 
propodos narrowing slightly distally, fringed on both sides with plumose 
sete, dactylos long curved and acutely pointed, not impinging against the 
propodos. Second gnathopoda similar in form to the first, but longer and 
more slender, carpus considerably broader than the propodos and of the 
same length, bearing two longitudinal rows of sparsely plumose sete which 
are as long as the joint itself; propodos narrow, tapering distally, fringed 
on both margins with long sete, dactylos slender, not impinging against
