These eleozooids and their distribution surrounding the autozooids invite comparison between E. whiteleyi and the Upper Cen- omanian bifoliate melicerititid Biforicula multicincta, the oldest known species of Biforicula (see Voigt, 1989) The principal qualitative difference between E. whiteleyi and B. multicincta is the existence of cancelli in the latter. It there- fore seems possible that E. whiteleyi belongs in the stem- group of Biforicula. Distribution. France. Lower-Middle Cenomanian of Normandy, Genus SEMIELEA d'Orbigny, 1853 Type species. Entalophora vieilbanci d'Orbigny, 1850, des- ignated by Bassler (1935: p. 198) as 'S. vielbanci D'Orbigny, 1853' fsicl. Other species. Semielea dichotoma d'Orbigny, 1853. Revised diagnosis. Eleid with tubular colony-form; axial lumen of subequal diameter lined by an inferred exterior wall; zooids in primary layer orientated parallel to tube length; autozooids fixed-walled; cancelli lacking. Remarks. D'Orbigny (1853) referred three species to Semie- lea. Only the first two are here retained in the genus; the third, Semielea plana d'Orbigny, 1853 is regarded as the base of Elea lamellosa (d'Orbigny, 1850) (see p. 19). Diagnostic of Semielea is the possession of branches with a
