This species was first described by Heller as IlippolyU 

 Pai/eri on specimens obtained during the famous Austro- 

 Hungariaii Polar Expedition ofF Franz Joseph Land. Låter 

 on it occurred at no less than three stations during the 

 Norwegian North Atlantic Expedition and it was referred 

 by Särs to Bythocaris instituted by him some years before. 

 Subsequently it has been found bj^ »Willem Barents» Ex- 

 pedition at one station in Barents Sea and by Birula off 

 Murman Coast. As seen above, it was obtained, during the 

 last Swedish Arctic Expeditions, at nine stations in a rather 

 considerable nnmber of individuals. 



My specimens do not show any differences from the 

 descriptions of Heller and Särs. Like the last author, I 

 have, however, in one fullgrown ovigerous female, observed 

 one distinct although small spine on the anterior part of 

 the dorsal carina, and also in some younger ones from the 

 same station, viz. stat. 18. 1899, a \&tj faint, nearly imper- 

 ceptible trace of the same. Some females were carrying eggs, 

 although the embryos were in a much less developed stage 

 than those of the preceding species.
