^{page 178 note 1} Beiträge zur Foraminiferenfauna nordalpinen, älteren Eocängebilde oder der Kressenberger Nummulitenscbichten. 4to. Munich, 1868. Extracted from the Transactions of the Royal Bavarian Academy of Sciences, Cl. 2; vol. x., Part II., pp. 581–730. With four plates.

^{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.

^{page 180 note 3} The plaæontologist has now a broader and firmer base, than heretofore, for his comparisons of fossil Ostracoda with the existing forms, in the late Memoirs on the living genera and species, by Mr. G. S. Brady; in the Transactions of the Zoological and Linnean Societies; the “Annals of Nat. Hist.;” the “Fonds de la Mer,” etc.
