Not illustrated. 1886 edition. Excerpt: ...Read before the Wellington Philosophical Society (Microscopical Section), 15th February, 1886. For some years past, whenever a Vorticella has come under my notice, I have made a sketch and taken careful notes. The receipt of a copy of Mr. W. Saville Kent's magnificent " Manual of Infusoria" has enabled me to identify most of the species observed. It should be remembered, however, that the present paper is only the result of a number of disconnected observations, and it must be distinctly understood that I do not for a moment claim to give an exhaustive list of the New Zealand Vorticelle; on the contrary, I believe that there are probably double or treble the number of species here enumerated, and it is hoped that some microscopist, with sufiicient time at his disposal to do the subject justice, may be induced to take up the search for and systematic examination of these flowers of the infusorian world. Vorticella annularis, Miiller. (Saville Kent, Inf., p. 689, pl. xxxix., figs. 28, 29.) I am doubtful about the identification of this species. Specimens agreeing with Kent's description and figure, except that they were much smaller and the pedicel shorter, were obtained in a stream at Karori in 1880. They were attached to the stems of partially-decayed leaves. V. marina, Greeff. (Saville Kent, Man. Inf., p. 685, pl. xxxv., figs. 1-8; pl. xlix., fig. 30.)

The body is slightly more tapering posteriorly, and the pedicel is longer than in Kent's description, being fully seven times the length of the body. V. oblonga, n. s. Body oblong, nearly twice as long as broad, ...
