C. biharensis. Pant., Fossil. Bacil. XJng ., p. 71, pi. xiv. fig. 119 ; 
pi. xvi. fig. 139. — Diam. -11 to *18 mm. Surface slightly 
depressed at centre ; somewhat convex about the semiradius. 
Central space absent ; a rosette sometimes present. Markings 
hexagonal, compressed in direction of radius, on a small, sharply- 
defined, rounded central area, extending to J or i of radius 
obtusely angular, large, unequal ; beyond this much smaller, 4 to 
in -01 mm., increasing slightly to about the semiradius, again 
decreasing gradually to the border ; broadish in a direction at right 
^angles to the radius, the central papillae prominent ; rows straight 
or slightly curved ; secondary subconcentric rows faint. Border 
narrow, hyaline. 
Habitat. — Elesd marl, Hungary (Pantocsek !). 
C. neogradensis. Pant., Fossil. Bacil. Ung., p. 74, pi. ii. fig. 18. 
— Diam. - 06 to *13 mm. Surface with two concentric undulations 
about the semiradius, the inner the more evident. Central space 
and rosette absent. Markings towards the centre angular 8, 
beyond the inner undulation rounded 6, between the hyaline 
spaces at the border somewhat larger, 5 to 5J in *01 mm., these 
spaces 15 to 27, narrow, subregular, with their long axes radial, 
each formed by the interruption of a row of markings ; rows 
straight, between the undulations moniliform. Border sharply 
defined; striae delicate, 16 in ’01 mm. 
Distinguished from C. intumescens by the undulations, markings, 
and hyaline marginal spaces. With this Cosmiodiscus barbadensis 
{Grev., Trans. Mic. Soc. Lond ., 1866, p. 80, pi. viii. fig. 12) may 
be identical. 
Habitat. — Also-, Felso-, Esztergdly, Kekko, Mogyorod, Szakal 
and Szent Peter deposits (Pantocsek !). 
C. intum.escens. Pant., Fossil. Bacil. TJng., p. 74, pi. ii. fig. 17. 
— Diam. *1 to *155 mm. Surface with a wide shallow undulation 
extending from a short distance within the semiradius almost to 
the border. Central space and rosette absent. Markings towards 
the centre angular 6J, soon becoming small rounded granules, 5-J- in 
*01 mm., at the border on an evident band again more minute ; 
rows straight, small subulate clear spaces opposite the origin of 
the shorter rows ; on the band adjacent to the border minute
