8Q 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, pl. viii, fig. 9, 10. 
Specific character. Conical, or subcylindrical, composed of 
longitudinal septz 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, pl. 
XxxXvil, fig. 3, and pl. xxxviil, 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 4Anthophyllum from the splendid 
work of Dr. Goldfuss, tab. xii, 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. gi Lees 
This zoophyte is occasionally found in the calcareous 
strata of New Jersey, and bears considerable resemblance 
to the recent species, A. glomeratus of Say.
