A small fauna of bryozoans is described from the Upper Toarcian of Belchite near Zaragoza, Spain. Microeciella gen. nov. is proposed for bereniciform tubuloporinids previously assigned to Microecia but differing from the type species of that genus in having small gonozooids with ovate dilated portions. Together with the type species of Microeciella, M. beliensis sp. nov., the Belchite bryozoans consist of M. reflexa sp. nov., 'Proboscina' cf. divisi Vine and an undetermined bereniciform tubuloporinid. M. reflexa is unusual in having an erect ancestrular tube from which a daughter zooid descends to reestablish contact with the substrate. The identity of various genera used for tubuloporinids of the 'Berenicea' type is discussed.
