Clavella sciatherica n. sp. 
The details of the reproductive system appear to be markedly different 
from those which obtain in Lernaeopoda. Instead of two separate vulvae, or 
apertures to the spermothecal ducts, there is but one prominent median 
opening surrounded by a funnel-like collar, which appears to represent the 
two vulvae fused. This leads into an enormously dilated spermotheca, the 
imperfect division of which down its median line seems to indicate its dual 
origin from two separate cavities. On either side of this division a spermato- 
phore has been lodged presumably by the attached males. Into the upper 
portion of the spermotheca enter the oviducts, while posterior to their 
entrance they quit this chamber, and, approaching close to the abdomen 
wall, terminate on either side of the anus at the point where the ovisacs will 
subsequently be suspended. The proximal (Fig. 6 Od.) and distal (Od 1 .)

elements of the oviduct are arranged at such an angle that it is conceivable 
that the ova of one side pass across the spermotheca for fertilisation and out 
on the opposite side. 
The males are each attached, by their maxillipedes, to the posterior 
region of the abdomen in the vicinity of the vulva, on either side of the anus. 
By means of an inwardly curved hook, which is minute and falciform, they 
pinch up the body wall of the abdomen into a little papilla. The vulva could 
be almost completely surrounded by the maxillipedes, which, when placed in 
apposition, have the conformation of an imperfectly closed tube suitable for 
the conveyance of a spermatophore. 
The ovisacs are long and slender, but do not taper; twice the length of 
the trunk, and containing eight rows of closely packed ova, 22 to 24 in a row.
