12 PLEIOCENE FOSSILS. 



This little coral, which is abundant in the sandy marls of the State, is identical with one 

 found in the Post Pleiocene. It presents considerable variation in the form of the cells, 

 which are, however, always more or less denticulated. From the Eocene species it is dis- 

 tinguished by the quincunx arrangement of the cells. 



The genus Lunulites is first found in the Cretaceous rocks, and occurs abundantly in the 

 seas of the actual period.

C. incrustans ; cellulis ovatis, immersis, cequalibus, subquincuncialilus, vet sine ordine

Description. Incrusting ; cells ovate, immersed, equal, somewhat quincunx or disposed 

 irregularly, surrounded by a row of minute pores. 



The clistiDguishing character of this beautiful species is the row of pores bounding the 

 cells ; on the sides of the cells, the pores are in double rows and seen obliquely, giving the 

 cells the appearance of serial arrangement. Vertically the cells are separated by a single 

 row of cells. This regularity is only observed when there has been no interference, for on 

 other portions of the same specimen both cells and pores are irregular. The mouth is large 

 and but slightly raised.
