Mr. A. W. Waters on the 
surface is beautifully ornamented with white spots, in the 
centre of which are the openings of the pore-tubes. In some 
there is an expansion at the end of the branch ; and in these 
the area of one or two cells is tumid, and the pores in this 
ocecium are much more numerous than in other parts. 
For the present I propose to call this var. vitriensis- and as 
it is from much greater depth than the others, it may be only 
the deep-water form. 
As the Alectos described in the British-Museum catalogue 
are not yet in the possession of the Museum, I have been 
unable to make any comparison with these, but do not see 
how the species are to be divided by the characters there 
given.

In a very large nunbcr dredged up in the Secca (Bay of 
Naples) there are great variations, some being much thicker 
than others and with more numerous cells; some show rugo¬ 
sity, which apparently depends mostly on age. In many the 
ends are clavate. The fiee ends of the zooecia measure about 
0'15 millim.
