The Danish Ingolf-Expedition danishingolfexpe19150304ingo Year: 1915 COPEPODA 153 The Jirsf pair of legs has the inner margin of the third basipodite less produced than in the preceding species; the Se of Re I is rather short, but strong, and the Se of Re II, which is fairl}' strong, extends only a little beyond the middle of Re III; the other natatory legs are scarcely different. The Jifth pair of legs is in main features like that of Ch. notacantha, but differs in several de- tails. The right endopodite (text-fig. 43 c) has a more regular shape, and has a somewhat different shape terminally; the third segment of the right exopodite ( 43 c) has, inwards, characteristic incisions and processes. The left endopodite has a more regular shape, and is terminally produced into a short tooth (text-fig. 43 d). The second segment of the exopodite is of more equal breadth throughout, and the third segment is distinctly more slender (text-fig. 43 e); the arrangement of the series of hairs on the posterior surface of Re III shows characteristic features of specific value (fig. 8 a PI. V). Text-fig. 43. Chirudina parvispina Farr. a. f cf. Abdomen X 22. b. Head X 22. c. Pes V dext. Ri + Re X c. 50. d. Pes V Ri sin. X 66. e. Pes V sin. Re II—III X 75- f. yc? (Stage IV).

This species has only been recorded by Far ran from the west coast of Ireland between 580 and 680 fathoms at 54°53 L. N. io°42 L. W. in the mouth of November 1904, and at 54°57 L. N. io°5i L. W. in the month of February 1905. Remarks. The specimen (young male) described by Far ran is scarcely different from my specimens. The female i
