Of tbis species two forms, analogous to the above-mentioned forms of C. tripos, occur, viz. f. oceanica n. f. and f. baltica n. f. The form oceanica is more robust and has shorter and more spiniferous horns, while f. baltica is more slender and almost destitute of spines. The figures by Bailey (1. c.) and Gran (Plankton, 1902, fig. 2) represent f. oceanica, to which my figures (140 and 141) also beloiig, but they have unusu- ally short antapical-horns, and one of them approaches C. arcticum Ehbg. C. longipes is a boreal, oceanic form, which occurs rather commonly along the Færoes all the year around; it reaches its maximum in the autumn. [See tables.] The form baltica belongs to the Baltic and the Ku Uegal and folio ws the waters of the Baltic west and northwards in the Skagerak and along the west coast of Norway. I have given a ligure of it, drawn after a specimen from the Danish waters, and Bergh's fig. 20 (Morphol. Jahrb., 1881) also belongs to Fig. 142.
