Tomopteris carpenteri: parapodium of specimen from St. MS 11. Discussion. In his Discovery report of 1930, Monro suggested that T. planktonis was probably the young form of T. carpenteri, but Augener (1929) had clearly demonstrated that this is not correct. Large numbers of young forms of T. carpenteri from the South Georgia surveys in the present material of the same size range as T. planktonis (compare the tables on p. 172 and p. 175) support Augener's conclusion. In T. planktonis the hyaline gland is normally unpigmented and apical on the neuropodium, whereas in T. carpenteri it is dorsal and always distinctly pigmented even in the very smallest specimens (compare Text-fig. 6, p. 173 and Text-fig. 7). Monro was able to see a copy of Augener's work before his report was published and he added a note to the effect that, if T. carpenteri and T. planktonis are separate species, his material from Sts. MS 11, MS 19, MS 22, MS 25, MS 31, MS 32, MS 34A, MS 62 and SS 21 would be T. planktonis. I have re-examined all these, except the specimen from St. MS 19 which is not in the () collections, and f
