Amaroucium sp., 
Although only one of the Scotea 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 Mungulus, 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. .

There are over forty specimens of this species in the collection, ranging in size from 
2x15 em. up to 65x 5 em. The majority are about 4 cm. in diameter. They have
