Nores on @ Pucuraiar Form of Potyzoa closely AuiiEp to 
Bueura (Kimetoskias, Kor. and Dan.), (With Plates I 
and II.) By Groresz Busx, F.R.S. 
Ar a meeting of the Scientific Society of Christiania on 
the 15th March, 1867, D. C. Danielssen gave a preliminary 
account of two new forms of Polyzoa found by him in Nord- 
land and Finmark, and referred to a new genus Kinetoskias 
Of these a fuller account has since been published by 
Koren and Danielssen, accompanied with figures ;” and one of 
the two forms in question was enumerated by Sars, in a 
catalogue of deep-sea species, under the name of Bugula 
Smitiu. 
In May, 1867, Professor Smitt, apparently not aware 
that a new generic name had been already applied to it by 
Danielssen, described apparently one of the two forms noticed 
by that observer under the name of Bugula umbella.> Smitt’s 
Specimens were procured from Wijde Bay, Spitzbergen. 
On the 30th January, 1873, on the “ Challenger” Expedition, 
a specimen of large size, of a form very closely allied to if not 
identical with one of those described by Koren and Daniels- 
sen, was described and figured by Sir C. W. Thomson,‘ 
under the name of Naresia cyathus. This specimen was 
procured in the North Atlantic in lat. 36° 23’ N., long. 11° 
18’ W., from a depth of 1525 fathoms. A second ‘specimen 
of the same form, but of smaller size, was procured on the 
2nd March, 1876, in lat. 36° 44’ S., and long. 46° 16’ W., 
from a depth of 2650 fathoms. Other specimens of a closely
