In 1887 a quadri-radiate Echinoconus (Galerites) subrotundus from the Lower Chalk of Shudy Camps, Cambridgeshire, was presented to the Woodwardian Museum by J. Carter, Esq., F.G.S. The specimen is in a good state of preservation, but it has been subjected to a slight amount of crushing, and this has caused (1) the apex of the test to be pushed backwards to a very small extent, and (2) an abrasion of the antero-lateral border. It has the subconoidal form of the normal examples of this species, but is subquadrate in section, and this is due to the fact that only four ambulacral and four interambulacral areas are present, the fifth area of both kinds being completely wanting.
