specimens." The chief groups of Foraminifera figured in the 

 " Mikrogeologie " are Tertiary and Cretaceous, from diiferent parts 

 of the world. The plates illustrative of specimens from the Chalk 

 of Meudon (pi. xxvii.) and of Gravesend (pi. xsviii.) have already- 

 been described in the Geol. Mag., Vol. VIII., pp. 511 and 563. 

 The figures of some Palaeozoic Foraminifera, from the Carboniferous 

 strata of Eussia, chiefly Fusulina (several species) and Endothjra, are 

 also elucidated by our authors. Endothyra sphceroidea (Ehr.) in the 

 Oolite ; Operculina turgida (Ehr.) in the Chalk of Eussia ; and 

 AmpTiistegina and Orhitoides, fossil in Java ; are amongst the more 

 interesting facts. A classified list of the fossil Foraminifera figured 

 by Ehrenberg, and a list of his generic names and their probable 

 equivalents, form Appendices to the paper under notice, the object 

 of which is thus stated by Messrs. Parker and Jones: — "We feel 

 certain that the better Ehrenberg's work is understood, his beautiful 

 and lasting illustrations, and his painstaking synoptical registers, 

 will largely advance the progress of biology in its relation to both 

 the present and the past. In removing some obscurity from the 

 highly valuable groups of Foraminifera of which he has treated, we 

 feel the pleasure of being of use to naturalists and geologists, 

 enabling them to put several extensive faunse and local groups into 

 close critical relation with each other, and with such as have been 

 observed by others. Further, we are sure that Ehrenberg himself, 

 thinking over the improved biological systems of later naturalists, 

 and open to conviction on good arguments, would freshly recognize 

 the force of his own words respecting the importance of rhizopodal 

 studies and their slowly progressive nature ; and be pleased to find, 

 also, his own researches not only serving as a broad basis for the 

 study in general and as steps to higher knowledge, but still more 

 freely trodden in the upward ascent, when made somewhat clearer 

 and firmer for the student."

Geologicai Society of London. — December 18, 1872.— Warington "W. Smyth, 

 Esq., F.E.S., Vice-President, in the Chair. — The following communications were 

 read:— 1. "Further Notes on the Punfield Section." By C. J. A. Meyer, Esq., 

 F.G.S. 



This paper was supplementary to one read before the Society by the author in 

 March of the present year (see Quart. Journ. Geol. Soc. xsviii. p. 245), and contained 

 the results of a fresh examination of the section at Punfield, and of the Wealden and 

 Neocomian strata of the Isle of Wight. He described the section exposed at bis 

 visit to Punfield as presenting:— 1. True Wealden beds; 2. a grit-bed with limestone 

 and paper-shales, containing fish-hones and Cyprides; 3. apparently argillaceous 

 beds; 4. a thin band of hard ferruginous sandstone with Atherfield fossils ; o. a clay- 

 bed, the upper part regarded as representing the "Lobster Clay" of Atherfield, the 

 lower sandy portion containing an abundance of marine fossils belonging to common 

 Atherfield species; 6. the so-called "marine band;" and 7. laminated clays and 

 sands with lignite. The author indicated the accordance of this arrangement with 

 what is observed elsewhere, and maintained that the grit-bed (No. 2), with its 

 limestone and paper-shales, containing Ci/pris and Cyreaa, was really to be regarded 

 as the passage-bed between the Wealden and the Neocomian.
