80 CRETACEOUS GROUP 



Maestricht, to which he gives the name of Retepora 

 clathrata, (Petrif. tab. ix, fig. 12.) 



Anthophyllum, Schweigg. 



A. atlanticum, (S. G. M.) PI. i, fig. 9, 10. 

 Journ. Acad. Nat. Science, vol. vi, pi. viii, fig. 9, 10. 



Specific character. Conical, or subcylindrical, composed of 

 longitudinal septae or plates diverging uniformly from a central 

 axis. 



Seldom more than inch in length, and one third less in 

 breadth. Each individual is attached by its base, and 

 surrounded on its remaining sides by a cavity, which 

 mostly terminates in a pointed cone. 



Common in the limestone of Gloucester county, New 

 Jersey. 



Faujas, in his history of the mountain of St. Pierre, pi. 

 xxxvii, fig. 3, and pi. xxxviii, fig. 1 and 5, gives draw- 

 ings of some fossils which appear to be generically the 

 same with those from New Jersey. But I derive the 

 characters of the genus Anthophyllum from the splendid 

 work of Dr. Goldfuss, tab. xiii, fig. 11. The specimen 

 delineated by that naturalist is stated to be from secondary 

 limestone near the Falls of Niagara. 



Alveolites. 



A. cepularis, (S. G. M.) 



Specific character 



This zoophyte is occasionally found in the calcareous 

 strata of New Jersey, and bears considerable resemblance 

 to the recent species, A. glomeratus of Say.
