In the ' Catalogue of Eock-specimens, Mus. Pract. Geol.' 1862, 

 p. 141, a piece of " grey slaty limestone " of tlie Lower-Piirbeck 

 Series, " with pale marly clay," in the " Soft Cockle-beds," and con- 

 taining pseudomorphous casts of salt-crystals, is described as having 

 its " n^Dper and under surfaces , . . . , as well as the casts of crystals 

 .... thickly covered with Ci/pris leguminella.'' Though these little 

 bodies at first sight closely resemble Darwimda leguminella, they 

 are really minute, subcylindrical, oolitic concretions * composing 

 the rock. They stand out whitish on the surfaces, more distinctly 

 than elsewhere, on account of weathering ; in the limestone they 

 have a brownish tint, and under the microscope the cementing 

 matrix is calcareous. Mr. Cunnington has shown me a specimen 

 from Chicksgrove (not far from Teffbnt), which has these oolitic 

 grains interstratified with a dense argillaceous limestone. 



In a grey marlj' limestone from Teffont, with chert, and containing 

 fish-remains (in the Eev. W. E. Andrew's collections), I have seen a 

 thin layer of similar oolitic granules, some botelloid, but most of 

 them round and ovoid. 



§ 5. Binystead Bay. 



376. Eingstead Bay. Prom H. B. W. July 1884. This is^ 



a mass of small roundish granules and Cypridse, 

 coated more or less with calc-sinter, including also 

 small tubes {SerpulcB ?). This is comparable with a } 

 similar Purbeckian bed near Boulogne, see ' Proceed. 

 Geol. Assoc' vol. Tiii. p. 58, and ' Bullet. Soc. Greol. 

 Prance,' ser. 3, vol. viii. p. 616. ;
