38 G. 0. SARS. [SEC. ARC. EXP. FRAM 
short, 7-articulate, 2nd joint the largest and without any projection 
behind; terminal part about the length of the 2 preceding joints com- 
bined. Posterior antenne and oral parts of the usual structure. 1st 
pair of legs less robust than in LZ. applanata, outer ramus very small, 
not even attaining half the length of the proximal joint of the inner, 
and composed of only 2 joints, the distal one much the longer; inner 
ramus rather slender, with the apical claw long and only slightly curved. 
Natatory legs of a structure similar to that in L. perplewa Scorr. Last 
pair of legs likewise rather similar, though differing somewhat in the 
shape of the distal joint, which is not, as in the latter species, trun- 
cated at the end, but is obliquely produced. 
Male with the anterior antenne very strongly hinged, the last joint 
of the proximal part being almost globularly dilated. 2nd pair of legs 
scarcely larger than in female, but with one of the sete of the inner 
ramus, as in ZL. brevirostris Ciaus, peculiarly transformed. Inner 
ramus of 3rd pair of legs transformed in quite a normal manner, being 
d-articulate, with the middle joint produced outside to a comparatively 
short spiniform projection, outer ramus, on the other hand, scarcely 
different from that in female. 4th pair of legs with the outer ramus 
somewhat stronger than in female, and having all the spines of the 
outer edge coarsely denticulate. Last pair of legs very small, with the 
inner expansion of proximal joint quite obsolete. 
Length of adult female 0.95 mm. 
Remarks. — This form is closely allied to L. perplexa, Scort, 
but is of considerably larger size, and moreover differs conspicuously 
in the more produced caudal rami, the comparatively shorter anterior 
antenna, and the shape of the distal joint of the last pair of legs. 
Finally, the male exhibits in its sexual characters several well-marked 
differences, as pointed out in the above diagnosis. 
Occurrence. — Several specimens of this form occurred in 2 of 
the bottles examined. 
Fam. Cletodids. 
127. Cletodes similis, Scorv. 
A solitary female specimen of this form was found in a bottle 
containing specimens taken on July 12, 1900, in the bay at Land’s End. 
Fam. Tachidiidz. 
128. Danielssenia typica, Borcx. 
This form occurred occasionally in 3 of the bottles examined.
