Escharina sarthacensis may be the young, unilaminar stage of this 
species. Eut even so, the specific name of tuherosa is preferable; 
as when d’Orbigny figured Escliarina sarthacetisis in 1851 either he 
regarded that as identical with his Escliarina sarthacensis of 1850 
(Prod. Pal. Yol. ii. p. 175), or the name was a synonym.

This Bryozoan is most neaidy allied to Reptomultelea tuherosa, 
Orb., from which it differs most markedly in the shape of the 
avicularia ; they are lanceolate and not hour-glass shaped.
