discovered parasitically attached to the medusa (Willsia stellata); it is less than 
one line in length ; pellucid ; eyes, hyaline; the generic name was suggested by the 
foot-like appearance of the posterior sucker. (W. Clark) On Ancylus oblongus 
and A. fluviatilis. We are glad to see that this veteran malacologist has entered 
upon the subject of our native fresh-water shells. The result of his investigation in 
this Paper is, that the Ancylus fluviatilis and A. oblongus hold the places assigned 
to them in Professor Forbes and S. Hanley’s “British Mollusca,” although we must 
say that, on our beginning to read the article, we were of the opinion that they 
would have been made out one and the same species. (E. Claparede) On Acti-

on the coast of the Colony of Victoria, Australia We have here short descriptions 
of five new genera of algse, and seven new species, which are but a foretaste of 
the many new discoveries Professor Harvey is making in the “far west,” and which 
we hope soon to have recorded in a more substantial form than in the pages of a 
periodical. We may observe, that all the new generic names are given in honour 
of persons who have attained celebrity for their scientific investigations ; this we 
think but right. (J. Cleland) Some Remarks on Vegetable Placentation. The
