250 DISCOVERY REPORTS 



SIPUNCULIDAE 

 Considerable collections of these animals were secured both in the Antarctic and on 

 the outward and homeward voyages. Since these latter stations are incidental to the 

 Antarctic survey proper and the species secured are tropical ones, the two sets of species 

 are listed separately.

This species has been recorded by Theel from South Georgia and the Graham Land 

 region. It was also taken by the B.A.N.Z.A.R.E. on the edge of the Antarctic Continent 

 off Adelie Land, etc. The Discovery collections show that it occurs over a much wider 

 area of the Antarctic. In these collections it was not taken in the Graham Land region, 

 although already recorded from there, but was taken at South Georgia. It is now 

 recorded from the Falklands and, more interestingly, from four stations in the Ross Sea. 



There is not a great deal to add to Theel's excellent description, but the number of 

 specimens in the Discovery collections enables the description to be elaborated at one 

 or two points. In Theel's specimens the skin was thin, shining and semi-transparent. 

 While this was true of the small specimens in the collection and a number of the large 

 ones taken by the 'Discovery', other large specimens had the skin over the introvert 

 or over the whole body dull and opaque. In some the introvert was stained with brown 

 or black. 



Theel has also described the papillae in his specimens as being cylindrical over the 

 body except at the girdle of vesicles, but in all these Discovery specimens as the girdle 

 of vesicles was approached from the anterior end the papillae tended to be more or less 

 swollen at the base and had the general appearance of a narrow cone. In some of the 

 specimens one or two of the papillae were set on isolated vesicles.
