N. neumayri, ci. N. australe, Hodgson. (All x 27.) The Discovery specimens from St. 170 agree with the co-types of A. australe; the lateral processes are but little separated, the legs are relatively stout and bear numerous long setae. The majority of the specimens, however, have the legs more slender and less setose, the body less compact, and thus agree more closely with A. australe var. aiistriiiorum, Hodgson. Many of the specimens, especially those from St. WS 32 to St. 144 (in the list of stations) are even less setose than the atistrinormn forms. Loman (1923, p. 13) has emphasized the importance of the number of denticulate spines on the four terminal segments of the oviger in the genus Nymphon. In nine co-types of A. australe examined the total number of denticulate spines varied from twenty-three to thirty, and in six co-types of A. australe var. austriiwnan from thirty to thirty-seven. The greater number in the variety is probably due to the fact that the specimens are of considerably larger size than the typical forms. At any rate, the number varied from twenty-eight to thirty-four in all samples of the Discovery material ' Hodgson (1907, p. 35) states that in N. australe var. ausirinorum the 'tarsus and propodus together ar
