. The Danish Ingolf-Expedition. Scientific expeditions; Arctic Ocean. 'la. Fig. T. Boreomysis scyphops G. O. Sars, 1 a. right eye, X y; 1 b. right autennal squama, slightly more than x 6. Fig. 2. Boreomysis distinguenda n. sp. 2 a. right eye, X 7; 2 b. right autennal squama, X 62(3. upper and the posterior margin. In B. scyphops the eye-cup is relatively flatter and [higher (fig. 1 a) the proportion between height and length being about as 21 : 26, the protruding rim is narrow, fre- quently even narrower than shown in the figure, and the distal upper lobe at the front margin is often rudimentary. A comparison between fig. 1 a and fig. 2 a will convey a good idea of the difference in outline and excavation of the eye-cups in the two species. Finally the antennal squama is slightly narrower in proportion to length in B. scypliops than in B. distinguenda. It may be added that I have a proportionately large material of Boreomysis from the Arctic vSeas, the Atlantic, the Indian Ocean and the Pacific; the material comprises nearly all hitherto established and several undescribed species. Some species are closely allied, and a thorough study is needed in order to avoid mistakes. 6. Boreomysis tridens G. O. Sars. 1870. Boreomysis tridens G. O. Sars, Christiania Vid. Selsk.
