Douvillinella sp.

Pl. 1, Fig. 4

M a t e r i a l. One incomplete dorsal valve (PCZCU

2264).

D e s c r i p t i o n. The dorsal valve is flat, with an estimated 22 mm width, thin-walled. The cardinal process is of a stropheodontid type. Socket ridges are short, widely divergent, not joined by cardinal process lobes. Long thin dorsal side septa and a faint median ridge are present. Endospines are low, densely covering the visceral area. Ornamentation is multicostellate with straight costellae also on the posterolateral flanks.

R e m a r k s. The dorsal valve (Pl. 1, Fig. 4) is referred to Douvillinella on the basis of its interior and uniform ornamentation. Due to its multicostellate ornamentation, the shell differs from the associated fragments which have parvicostellate ornamentation and are herein referred to Protodouvillina cf. interstrialis ( PHILLIPS, 1841) .
