Generic Character. — Zocecia urceolate, erect or sub- 

 erect, heaped together and irregularly disposed ; the ori- 

 fice terminal, loith one or more ascending rostra in con- 

 nexion with it, bearing avicularia. Zoarium inomsting , 

 often composed of many layers of cells, or erect and ramose. 



The species to which Fabricius applied the name Celle- 

 pora were, with a single exception, members of the old 

 genus Lepralia. But that exception is the well-known 

 C.pumicosa ; and it has so happened that it has been taken 

 as the type of his genus, and the name has passed into 

 general use in connexion with the present group. In any 

 case there would have been little ground for interfering 

 Avith the common usage ; and noAv that the genus Lepralia 

 is dismembered, all pretext for such interference would 

 seem to be removed. 



a. Orifice without a sinu^ ; zoarium incrusting.
