CELLEPORA DEPRESSA — (New Species.) 



Plate IY., Fig. 9. 



C incrustans • cellulis, depresses, ellipticis quincuncialibus • ore rotundo, prominulo, labiato, 

 tuberculoso. 



Description. Incrusting; cells depressed, elliptic, quincunx; mouth circular, slightly 

 prominent, margined, tuberculose. 



The cells are much flattened, somewhat indistinct, and separated by a depressed line. 

 The mouth is small and depressed, with the lip slightly raised and thickened. On each 

 side of the mouth there is a minute tubercle.

In the revision of Brtozoa, D'Orbigny has restricted the genus Cellepora, Fab., to those 

 species composed of a single layer of cells. He has also referred the species of Escharina 

 and Bschaeoides, of M. Edwards, and Discopora, Lam., to this genus. Celleporaria, 

 Lamouroux, contains the branching species placed in Cellepora, by Lamarck and others, 

 and Reptocellepora has been instituted for those species composed of several cell-layers, 

 heretofore included in Cellepora. 



MEMBRANIPORA.— Blainville.

M. incrustans, tenuis j cellulis contiguis, ovalibus vel sub-liexagonalibus, diver gentibus 

 quincuncialibus. 



Description. Incrusting, thin, cells contiguous, oval or somewhat hexagonal, diverging
