SoUas, W. J. On Euhrochvs clavsvs, a Vitreo-hexactinellid Sponge 



from the Cambridge " Coprolite " Bed. Geol. Mag. dec. ii. vol. iii. 



pp. 398-403, pi. xiv. 



Describes and figures a remaikable siliceous sponge, a derived fossil 



from the U. Gault. It is a clavate solid sponge, the skeleton of which 



consists of an originally siliceous network, characterized by sexradiate 



knots, filling the interior, and forming on the exterior a rectangular 



meshwork. The genus EuhrocTins is founded for its reception ; and its 



relations with Farrea are pointed out. H. A. N. 



. On the Glauconitic Granules of the Cambridsre Greensand. 



Geol. Mag. dec. ii. vol. iii. pp. 539-544, pi. 21. 

 Treats of the minute bodies included in the phosphatic nodules of 

 the Cambridge Greensand, as shown by transparent sections. Some of 

 these bodies are arenaceous and perforate calcareous Foraminifera. 

 Others are glauconitic granules, which contain in their interior minute 

 Foraminifera, coccoliths, coccospheres, and other bodies. The cocco- 

 liths and coccospheres are specially treated of, and various forms 

 figured. Concludes that the precipitation of glauconite has been de- 

 termined by the presence of animal matter; and whilst many granules 

 show some nucleus, such as a Foraminifer or a coccosphere, other 

 granules, which show no such nucleus, have been the result of the 

 deposition of glauconite round the decaying matter of soft-bodied 

 Protozoa and Protista. H. A. N.
