Excerpt from Bulletin From the Laboratories of Natural History of the State University of Iowa, 1896-1898, Vol. 4The following notes are based upon observations made during April and the first half of May, 1895. Although the Plumularidw were the special objects of study, a number of facts concerning other forms were noticed, which, together With the discussion of certain matters brought out in the special study of the Plzmmlaridw, were considered by the Director to be of sufficient interest for publication in this Journal. It will be understood that no general discussion of the hydroids at Plymouth is attempted, nor is it my purpose to give a list of the hydroid forms of that exceedingly rich field, no Species being mentioned unless some new fact has been Observed concerning it.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
