G. rotatorius : Db Koninck, Carb,Fossilcs de Belgique, page 565, plate 50, fig. 1.[ See Note at the end of this paper.]15 This species, from thesame locality as the prece-ding, has been identifiedwith the European form. Inthe absence of Europeanspecimens, I have onlymeans of comparison withfigures, and am unable topoint out specific general form of shell,and proportions of volu-tions, this fossil does notgreatly differ from G. pa-tersoni j but the presenceof a large umbilicus, andmore complicated septa inthat one, are distinguishingfeatures. The accompanying dia-gram will suffice for com-parison with the precedingspecies. GONIATITKS ROTATORIUS.
