Notes on the Polyzoa, Stomatopora, and Proboscina groups, from the Cornbrash of Thrapston, Northamptonshire

Abstract

In his illustrations of the “Geology of Yorkshire,”* Mr. John Phillips referred only one species of Polyzoa to the “Zoophyta” group, which he found adhering to fossils derived from the Cornbrash Rocks of the Yorkshire coast. This species Phillips named Cellaria Smithii. “It seems,” the author says, “to belong to the genus hippothoa, Lamx., see his Expos. Meth. t. lxxx., fig. 16, Scarborough, attached to cardium citrinoideum.” Phillips. In Mons. Jules Haime’s description of the “Fossil Bryozoa of the Jurassic formation, † the author only cites one species (p. 180), Berenicea lucensis , as found in the Great Oolite, Hampton Cliffe, and also in the Bradford Clay and Cornbrash. From material, at that time in my possession, and also from a careful study of the Polyzoan fauna preserved in the cases of the Museum of Practical Geology, Jermyn Street, I was able to record, and partially describe, in my third “Report on Fossil Polyzoa,”‡ the following Cornbrash examples:— 1. Stomatopora Waltoni, Haime Cornbrash, Stanton. 2. „ dichotoma, Lamx „ ,, 3. Terebellaria ramosissima, Lamx „ „ 4. Diastopora microstoma, Mich (?) „ ,, In another paper on the “Jurassic Polyzoa found in the neighbourhood of Northampton”|| I also described amongst others, and partly illustrated, the following species: 1. Stomatopora Waltoni, Haime, Cornbrash, Bedford. 2. Diastopora Oolitica, Vine „ ,, 3. „ Davidsoni, Haime „ „ 4. Terebellaria ? increscens, Vine. Since these papers were written I have been allowed to examine, study, and select, from more than six hundred fossils, a ...
