foot up to the end of the body. Chromophil glands appear on the neuropodial pinnule, ventral to the 

 parapodial trunk on all feet from the fourth backwards (Text-fig. 7). They are much bigger in the 

 adult than in the young forms but apart from size there is no structural difference. There is no tail 



in this species.

Text-fig. 7. 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 1 1 , MS 19, MS 22, MS 25, MS 3 1 , 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 B.M.(N.H.) collections, and find that in fact they are all young 

 T. carpenteri, except the specimen from SS 21 which is T. planktonis. Monro noted also that all these are 

 coastal stations (actually SS 21 is not), the suggestion being that the specimens might represent an inshore 

 breeding species. This note will be discussed later (pp. 224-228), but it can be stated here that in the 

 present work the smallest specimens of T. carpenteri have been found only in the neighbourhood of South 

 Georgia. 



In 1925 Mcintosh reported T. carpenteri from off the Cape of Good Hope, 33 46' 00 S., 

 17 13' 00 E. It is unfortunate that this specimen is not available for examination, but it is described 

 with a tail, with frilled margins to the pinnules, and is figured with a deep indentation in the anterior 

 border of the antennae: it is clearly T. nisseni (see pp. 180-181).
