B. gracilis and B. papyracea by tbe greater proportional shortness 
of the zooecia. 
Young forms of B. papillosa resemble B. polystoma (E,om.), but 
the zooecia are less raised, and the resemblance is lost before the 
zoaria are mature. Young specimens also resemble those of 
corresponding age in B. disciformis, Hag., in -^hich the zoarium is 
much thicker. Hamm,^ it may be remarked makes B. papillosa 
(Ess.) a synonym of B. disciformis, but the two species seem quite 
distinct. 
The Jurassic representative of B. papillosa is B. scolinula 
(Mich.),^ which has larger zoaiia and less elevated peristomes. 
B. papillosa also resembles the Jurassic B. archiaci, Haime, 
in the shape of its gonocysts, which sometimes occur in 
irregular circular bands, as shown in a specimen figured in Cat. 
Jur. Bry. pi. iv. fig. 1. In zoaria of B. archiaci, with scattered 
gonocysts there is a similar patchy aiTangement of the apertures 
as in the B. papillosa, var. grandis (Orb.). B. archiaci differs, 
however, from B. papillosa by having the apertures less regular in 
distribution and more crowded on the margin. 
Berenicea minima, from the Leithakalk near Yienna is probably 
the nearest Cainozoic representative of this species ; the gonocysts 
are not shown in von Eeuss’s^ figure, and the peristomes are more 
regularly distributed than in the Cretaceous form.
