G. megalops can at once be distinguished from the other species of the genus by the well-developed broad rostral plate, which is produced forward to cover the bases of the eyes and the whole of the first segments of the antennular peduncles, by the presence of a slender spine in the inner margin of the endopod of the uropod, by the relatively greater length of the telson, the length of the apical spines and by the presence of three long p

G. megalops can at once be distinguished from the other species of the genus by the well-developed broad rostral plate, which is produced forward to cover the bases of the eyes and the whole of the first segments of the antennular peduncles, by the presence of a slender spine in the inner margin of the endopod of the uropod, by the relatively greater length of the telson, the length of the apical spines and by the presence of three long plumose setae between them. The most remarkable feature of the specimen is the peculiar form of the eyes but, as this may not be normal, I have relied upon other features for the identification of the species and trust that further specimens may come to light so that the true nature of these organs may be ascertained. Distribution. Atlantic Ocean, to the west of Cape Town. Genus Meterythrops S. I. Smith, 1879 1879 Meterythrops S. I. Smith, p. 93. 1879 Parerythrops (pars) G. O. Sars, p. 98. Remarks. This genus very closely resembles Parerythrops in the general form of the antennules, antennae, eyes, mouth-parts and telson, but differs in the form of the first pleopods of the male. In Parerythrops these appendages are rudimentary as in the female, but in Meterythrops they are as in Erythrops, well-developed, biramous, with the exopod normal and multiarticulate and the endopod reduced to a single segment.
