the “ continuity of the chalk.” We had another successful haul 
of the trawl on the 30th in 1525 fathoms, a little farther to the 
south-west of Cape St. Vincent. The chief prize on this oc- 
casion was a Bryozoon of singular beauty, and differing very 
widely in structure and habit from all previously discovered 
members of the class (Fig.80). A straight transparent stem, 
like the stem of a claret- glass, 60 mm. in length and 5 mm. 
wide at the base, contracting to half that width at the top, rises 
from a tuft of fibrous roots, and supports on its summit a very 
graceful cup formed of branches, which, in their general charac- 
ter, somewhat resemble those of the ecencecium of the common 
Bugula neritina. The backs of the zocecia are turned outward, 
and the openings toward the interior of the cup, and a large 
avicularium is attached to the wall of each cell. The bases of 
the branches are connected together to a height of about ten 
mm. by a transparent membrane. The ecell-bearing portion of 
the ccoencecium ends beneath in a curiously abrupt way at the 
side of the top of the stem, with which it does not seem to be 
in any way continuous. The stem passes into the membrane 
supporting the base of the cup, and the stem and membrane, 
and the cell-bearing branches, are so different from one another 
in appearance, that one was inclined to make sure, in the first 
place, that he was dealing with a single organism, and not with 
some singular case of “commensal” association. We got, how- 
ever, many specimens of the same species in all stages of growth 
in the deep water of the Mid-Atlantic, and also one or two al- 
lied forms which appeared to lead up to it. The transparent 
stem may probably homologate with the stem of Lozosoma, 
but the branches of the zoccia and the polypides are certainly 
those of a normal cheilostomatous Bryozoon not far from Bu- 
guia. This remarkable form was dedicated to Captain Nares 
under the name of Varesia cyathus, as an early recognition of 
the confidence and esteem with which he had already inspired 
the civilian scientific staff. Varesia,in the form and structure
