l82 DISCOVERY REPORTS 



extend a little beyond the body length. Hyaline glands appear on all notopodial and neuropodial 

 pinnules from the third feet. They are distinct in most specimens and apical in position near the apex 

 of the parapodial rami. Chromophil glands occur ventrally on the neuropodial pinnule of all feet 

 from the third backwards, except in the specimen from St. 2081 where they appear first on the fourth 

 foot. A tail is normally present but is frequently broken off. 



Discussion. As noted on p. 173, I think it possible that two of the specimens reported by Monro 

 (1930) as T. cavallii are T. krampi. Most of the Discovery material examined here is larger than the 

 original specimens recorded by Wesenburg-Lund (1936), who gave a size range of 10-15 mm - m 

 length by 4-5 mm. wide, or by Stop-Bowitz (1948) who reported one of the larger of his specimens as 

 10 mm. long by 4 mm. wide. Both these authors noted that the chromophil gland began on the 

 fourth foot, whereas in my material this is the case in only the smallest specimen. It is probable that 

 as development proceeds, the chromophil gland appears on the third foot. Both Wesenburg-Lund 

 (1936) and Stop-Bowitz (1948) regarded T. krampi as closely related to T. elegans, but I think it is 

 much closer to T. nisseni or T. kempi. T. nisseni is normally much bigger than krampi, but apart 

 from size differs only in lacking a first pair of chaetigers and in the arrangement of the hyaline 

 glands; T. kempi also differs in being without a first pair of chaetigers, but has rosette glands 

 instead of hyaline glands (p. 183). The size range of Monro's smaller specimens of T. kempi (p. 182) 

 covers that found here for T. krampi, otherwise I would have suggested that the material above 

 represents the young stages of T. kempi which possibly lose the first pair of chaetigers on becoming 

 adult. 



General distribution. Known only from the Atlantic, off south-west Iceland, Southern Greenland 

 (Wesenburg-Lund, 1936) between the Canaries and the Azores and between Newfoundland and 

 Ireland (Stop-Bowitz, 1948) T. krampi is reported here for the first time from the South Atlantic, 

 probably having the southern limit of its distribution at the Sub-Tropical Convergence (see p. 250).

There is a small indentation in the middle of the antennae and a pair of indistinct eyes on the 

 prostomium. The first pair of chaetigers is missing; the second pair about two-thirds the body length 

 in the larger specimens, but in the small ones the chaetigers are a third as long again. On the third 

 parapodia and all subsequent feet there is a black spot on the notopodial and neuropodial pinnules,
