Abstract
The present paper is the result of an examination of some material kindly sent me by Mr. Llewellyn Treacher, who obtained it from about the middle of the phosphatic band at Taplow. A short list of the foraminifera of the Taplow Chalk has already been given by A. Strahan, Esq., M.A., F.G.S., of H.M. Geological Survey, with the assistance of Prof. T. Rupert Jones, F.R.S., F.G.S., and I wish at this point to express my obligation to the latter for help and advice in preparing these notes. The material used was excessively rich in well-preserved specimens of foraminifera, forming perhaps 75 per cent. of the whole; and a series selected from it proving so extensive and interesting, there seemed good cause to communicate a list of them. On treating the disintegrated chalk with a weak solution of hydrochloric acid, the most perfect casts in phosphate of lime are obtained, the Rotaline forms being especially noteworthy. The total number of species and varieties of foraminifera found is 98; and to these must be added 5 species and varieties of ostracoda, represented by 11 specimens. All the forms of ostracoda herein noted have been previously found in the Chalk. They are:— Pontocypris triquetra , Jones, sp., 2 specimens; Bythocypris silicula , Jones, sp., 1 specimen; Cythereis auriculata , Cornuel, sp., 1 specimen; C. Wrightii , Jones and Hinde, 6 specimens; and Cytherella Williamsoniana , var. granulosa , Jones, 1 specimen. Of the 98 varieties of foraminifera, 5 appear to be entirely new to science, whilst altogether 30 are new
