PNODICAVA, d’Orbigny, 1854. 
[Bry. Cret. p. 1013.] 
Nodicava pustulosa, the first of the four species referred by 
d’Orbigny to this genus, is included in the genus Ceriocava 
(B.M. Cat. Jur. Dry. 164). D’Orbigny described two Cretaceous 
species, the position of which seems to me indeterminable from 
the available information. M. Pergens rejects Nodicma as an 
“ undulated Melicertites^^ (Rev. p. 386), in which case d’Orbigny’s 
figure is very misleading.
