SYSTEMATIC ACCOUNT i6i The differences listed above appear sufficient to justify the removal of Nordenstam's E. tiibercidata from the species and to institute a new one, E. oculopetiolata, to receive it, together with similar specimens from the Discovery collections. Description. The antennule (Text-fig. ()d) is considerably longer and stouter than the antenna (cf. the published figures of E. tuberculata of Ohlin, 1901, pi. iii, figs. 10a, 2, where the antenna is much longer than the antennule).

SYSTEMATIC ACCOUNT i6i The differences listed above appear sufficient to justify the removal of Nordenstam's E. tiibercidata from the species and to institute a new one, E. oculopetiolata, to receive it, together with similar specimens from the Discovery collections. Description. The antennule (Text-fig.

The first peduncular joint is slightly longer than the other two, which are of approximately equal length, the inner distal angle of the second joint is produced to form a well-marked projection. The clavate flagellar joint is slightly shorter than the third peduncular joint, and bears, in the male, a number of long sensory setae on its anterior margin. In the female these are fewer in number and are restricted to a small tuft at the distal extremity of the Text-fig. 9. Edotta oculopetiolata (a) Antenna, x 22. (6) Left maxilla, x 42.

The antenna (Text-fig. ga) consists of a peduncle of five joints and a flagellum of two very short ones (cf. Ohlin, 1901, p. 293 and pi. xxiii, fig. loaz, where the flagellum consists of three joints, the first one of which is of considerable length). The first four peduncular joints are short and subequal, the fifth is nearly twice as long as the fourth. The flagellum is extremely short; the distal joint is much smaller than the basal one, and bears a tuft of long setae. The mandibles are described and figured by Nordenstam (1933, p. 95, fig- 22a, b). The outer lobe of the maxillula (Text-fig. ge) has ten spines on its obliquely truncated extremity, and a few scattered setae both on its inn
