PROFESSOR W. A. HERDMAN ON THE 



Although only one of the Scotia Tunicata requires to be described as new to science, 

 several of the species are of considerable interest, and most of them add something to 

 our knowledge either in the characters and variation of the species or in distribution. 

 The one new species (Fungulus antarcticus) is a very remarkable form belonging to the 

 deep-sea genus Fungulus, known only from a single species obtained during the 

 Challenger Expedition between the Cape of Good Hope and Kerguelen Island. 



This collection shows again what I remarked upon more than twenty years ago in 

 the case of the Challenger collection, that the Ascidian fauna of the far South is 

 characterised by the abundance and the large size of the individuals of a comparatively 

 few species. Halocynthia setosa and Holozoa cylindrica are the two largest species, the 

 one simple and the other compound, and both are represented by a large number of 

 specimens. I have, however, written on this matter, and also on the number of Antarctic 

 as compared with Arctic species, so recently in my report * upon the Discovery collection 

 that these matters need not be discussed further here.
