Diagnosis. 
Fossils with a massive zoarium, usually consisting of globula^' 
bodies or constricted stems. The zooecia and apertures are 
very narrow in diameter and the apertures small. 
The surface is marked by curved ridges, between which the 
apertures occur. The apertures are usually quincuncially 
arranged along curved intersecting lines.

Affinities. 
This genus has been described under several names. It is 
characterized by its raised curved ridges which, according to 
von Hagenow,^ continue within the zoarium, and by the excep- 
tional smallness of the apertures. 
The structure has unquestionable resemblances to some Hydrozoa, 
and the determination of the aflSnities of this genus requires full 
microscopic examination, for which the material in the Museum 
Collection is inadequate. The Museum possesses two small 
specimens, and as external examination of them does not show 
anything to necessitate their exclusion from the Bryozoa, the genus
