 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

 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-

 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
