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, winch are irregularly shaped and angular on account of 

 mutual pressure, and the largest of them which contains half- developed young ones, is 

 2 - 73 mm. in length and P74 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 larvae. I took some larvse 

 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. 4 d) 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 antennulae. The olfactory seta of the antennula is tolerably short, may be about half 

 the length of the cephalothorax. The antennae 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 third joint. The mouth-border exceptionally broad 

 with distinct, thick hairs. The basal joint of the maxillae 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 inner 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 setae 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. 

 Pig. 4 a 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 larvse, but — as stated above — none of these was ready 

 1 i 1 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,
