obliquely in front of and at some distance from the genital apertures and somewhat closer 
to the median line than the apertures. The whole genital area is naked. Caudal stylets 
are wanting. 
MALE. Unknown. 
OVISACS. They differ widely in size, as fig. 4a shows; in the marsupium repre- 
sented occurred twenty ovisacs, which are irregularly shaped and angular on account. of 
mutual pressure, and the largest of them which contains halfdeveloped young ones, is 
2°73 mm. in length and 1°74 mm. in breadth, the smallest ab. ‘92 mm. long and °75 mm. 
broad. In another specimen the ovisacs are oval or sub-globular. 
LARVA. None of the ovisacs contained fully developed larvee. I took some larvee 
out of the ovisac which contained the most advanced specimens and prepared them out of 
their membranes, so that I succeeded in giving a representation (fig. 4d) of several of the 
most important appendages, but about the final shape of the larva etc. no detailed account 
can be given. The front has no decoration, at most a small list inside the anterior angle 
of the antennule. The olfactory seta of the antennula is tolerably short, may be about half 
the length of the cephalothorax. The antennze of medium length, 4-jointed, the two first 
joints broad, the third one slender, longer than the second, the fourth joint short, and its 
longest terminal seta shorter than the tbird joint. The mouth-border exceptionally broad 
with distinct, thick hairs. The basal joint of the maxille has two dense combs of fine 
processes (one of which is not visible in the drawing), second joint is slender, third joint has 
some spines on its inner margin. Second joint of the maxillipeds much longer than the 
third; the fourth joint has three conspicuous, slender and spiniform processes at the distal 
part of its immer margin. The abdomen of less than medium size; its first segment almost 
longer and somewhat broader than the second one, and its long spines reach far beyond the 
caudal stylets, which are distinctly set off from the small third segment. The setz of these 
stylets seem to be proportionally pretty short. 
POST-LARVAL DEVELOPMENT. Unknown. 
HABITAT. The marsupium of Munnopsis typica M. Sars from the Kara Sea. 
Fig. 4a represents the greater part of a large specimen of the host, in which the ovisacs of 
the parasite are visible through the diaphanous plates of the marsupium. The marsupium 
was pretty strongly extended, it contained twenty ovisacs, partly with eggs, partly with 
Nauplii or with more developed larv, but — as stated above — none of these was ready 
to swim out; the above described female was lying against the ventral side of the host towards 
its anterior end. In a smaller specimen were discovered nine ovisacs; the female and some 
sacs had evidently been washed out.
