page 179 note 1 Dr. Gümbel has instituted the new genus Venilina for those Textilarian forms that commence with an alternate series of compressed oblique segments (Grammostomum), and end in a single series, such as the bi-uniserial sub-varieties mentioned in Ann. N. H., ser. 3, vol. xi., p. 93.

page 180 note 1 The Rotalinœ have been especially studied by Mr. W. K. Parker, and his classification and definitions may be found in Carpenter's “Introd. Study of Foram.,” and in the “Phil. Trans.,” vol clv. (1865), p. 378, etc. To these works the attention of naturalists, treating of fossil and recent Rotalines, should be particularly directed.
