. Discovery reports. Discovery (Ship); Scientific expeditions; Ocean; Antarctica; Falkland Islands. a be Text-fig. 29. Serolis ovata {a) Maxilla, x 32. {b) Maxillula, x 32. (c) Maxilliped, x 32. This species can be placed in the key to the species of Serolis (Sheppard, 1933, pp. 279-82), in section BlClb (pleural plates on third abdominal segment extend beyond those of second) and in this group in 2y? (ii) (Uropods not broad and extending beyond the posterior extremity of the terminal segment). Thus, in general characters S. ovata comes nearest to S. exigua Nordenstam (1933, pp. 70-5), but can be readily distinguished from that species by the compact form of its body with its somewhat thickened coxal plates, and by the absence of a median backwardly projecting spine to the cephalosome. Distribution. Scotia Sea, 6i° 20-8' S., 54-04° 2' W. SUMMARY 1. The supplement records additional species of the family Serolidae from the Discovery collections made between 1928-37. 2. Two new species Serolis acuminata and Serolis ovata are described. REFERENCES Hale, H. M., 1952. Expedition. Reports, series B, vol. vi, pt. 2, pp. 32-5, text-fig. 4.
