With these figures, and facts cited bearing upon the problems concerned, there can hardly be reasonable doubt as to the con- clusions to be drawn. Syncoryne linvillei must be identified with the genus Corynitis; and the Corynitis of later literature must be identified with the genus Gem- maria of McCrady. It is therefore to be hoped that the long-standing confusion here referred to may be once for all removed by recognition of the facts as given. And while it is too much to anticipate that simi- lar confusion along kindred lines may be avoided entirely, the les- sons of past experience should count for something in rendering their occurrence less frequent, or of such persistence. Gemmaria.—Attention has been directed to the confusion of McCrady's Gemmaria with his very different genus Corynitis. A similar confusion has also been more or less current as to the relations of Gemmaria and Zanclea. The latter was instituted by Gegenbaur for a medusa found at Messina, and recognized by McCrady as having certain points of similarity to his doubtful Gemmaria, which he believed however, to be quite generically distinct from Zanclea. Having taken a medusa at Woods Holl during several years which is now well known as identical with McCrady's Gemmaria, and having kept these medusae at various times and for consider- able periods in the laboratory, I am convinced that they are beyond.
