Krohnii and differ sharply from the four other species of the group — and from every species of the genus— by having the conspi- cuous lobe of first antennular joint pectinate, with 5 to 10 very slender, spiniform denticles. The three species may be separated by the following diagnoses. E. Krohnii Brandt. —The lobe from first antennular joint not only with the row of spiniform denticles along the margin, but

Euphausia Krohnii Brandt. A. Inner lobe of left copulatory organ, from behind; p2. terminal process; p3. proximal process. B. Same lobe, from the inner side. thin process with about three similar denticles. Second antennular joint above at each distal angle with an obli- quely conical, conspicuous tubercle. The inner lobe of the copulatory organs (Fig. 4) has the terminal process mode- rately long and conspicuously widened towards the end which is broadly rounded with a minute lateral tooth ; the proximal process with three irregular, large teeth or pro- cesses on the distal third of the inner margin, while the most terminal part is quite flattened and much bent in a direction vertical on that of the three teeth, and the end itself rounded. — Length 14-19 mm.
