OCCURRENCE. — Middle Miocene: Austria ( Schmid 1989), Hungary ( Moissette et al. 2007). Late Miocene: Tunisia ( Moissette 1997).

DESCRIPTION

Colony vinculariiform. Frontal showing rectangular zooids organized in two alternating series with prominent distal and lateral edges.Cryptocyst concave,proximally well-developed and thus resulting in an elongate V-shaped opesia. Dorsal displaying enlarged triangular vibracularia with long setal grooves and large radicular pore. Frontal avicularia and ovicells not observed.

REMARKS The closeness with the Recent Canda retiformis Pourtalès has been emphasized since the creation of C. rectangulata . A revision of both fossil and Recent material of the genus Canda is desirable.
