156 Triassic Echinoderms of Bakony. 
Original of Minster (1841), pl. Ill, f. 12. The holotype of Cidaris remifera. 
The specimen is slightly crushed, so that the thickness was probably greater than 
the actual measurements. The appearance of a median depression is perhaps not 
wholly due to crushing. The thickness is here measured between the flat blades 
of sliding callipers, and the median depression is therefore not taken into account.

A smaller and less complete specimen of the same general form as a. Miun- 
STER collection. Paratype of C. remifera. Note the slight median depression, 
partly due to crushing, but in the measurement this is compensated to some extent 
by a film of matrix.
