Discovery reports (1962) Discovery reports discoveryreports30inst Year: 1962 I-WS 143 Fig. 29 Fi8- 3° Text-figs. 29 and 30. Occurrence of Tomopteris carpenteri round South Georgia. Fig. 29. Adults. Fig. 30. Juveniles. Meridian, they would have been picked up by the N 70 V nets, because specimens of T. planktonis and T. septentrionalis within the same size range were collected there and also round South Georgia. However, the numerous records of 'Tomopteris unidentifiable' listed in Appendix I from South Georgia and the o° Line must be considered. I do not regard any of these as young T. carpenteri, but they are listed as unidentifiable because I cannot decide if they are T. septentrionalis or T. planktonis? The principal diagnostic characters of these last two species (the diffuse chromophil and hyaline glands), have been destroyed in all the specimens not identified. In juvenile T. carpenteri how- ever, the hyaline gland is dorsal on the parapodial pinnule and has escaped destruction affecting the apical region. I suggest that T. carpenteri may breed around South Georgia but not in the open ocean. Previous records. Juvenile specimens of T. carpenteri have previously been collected only by the 'Norwegica' but not from the Atlantic Ocean, Stop-Bowitz (1949) reporting three specimens from the Pacific at 67° 30' S., 91° 33' W., 50-0 m., and 66° 48' S., 79° 56' W., 100-50 m. Monro (1930) recorded eleven juvenile specimens from seven Marine Station shallow hauls made in Cumberland Bay South Georgia, as either T. carpenteri or T. planktonis. I have examined them and find them all to be carpenteri. Considering the large collections which have been made in the Antarctic Zone of 1 Except by Mcintosh (1925); as noted on p. 175 this record is probably T. nisseni. * Theoretically it is possible that there are also several other species of the same size range including T. cavalh (see pp. 173 -174)- 9-2
