288 Organic Remains of the Ferruginous 



ZOOPHYTES. 



ANTHOPHYLLUM. Schweigg. 



A. atlanticum. (S. G. M.) This genus, a Linnean madrepore, is 

 common in the limestone of Gloucester county, N. J. Its form is cyl- 

 indrical, or subconical, seldom exceeding three fourths of an inch in 

 length, and is about one third less in diameter. It is formed of lon- 

 gitudinal septa, or plates, which diverge from a central nucleus. 

 Each individual is attached by its base, and is surrounded on the re- 

 maining sides by a large cavity. Faujas, in his history of the moun- 

 tain of St. Pierre, pi. 37, fig. 3, and pi. 38, fig. 1, and 5, gives 

 drawings of some fossils which appeared to be generically the same 

 with those from New Jersey. But I derive the characters of the ge- 

 nus Ant hophyllum from the splendid work of Dr. Goldfuss, tab. 13, 

 fig. 1 1 . The specimen delineated by that naturalist is stated to be 

 from secondary limestone near the Falls of Niagara. 



ESCHABA. Lam. 



Fragments of this genus (millepora, Lin.) are of frequent occur- 

 rence with the fossil last described. They bear considerable general 

 resemblance to a species in Ellis's Nat. Hist, of corallines, pi. 28, fig. 1 . 



FLUSTRA. Lam. 



Abundant in the same matrix with the preceding genera, and is 

 nearly allied to the species figured by Ellis, pi. 29, fig. a. 



RETEPORA. Lam,. 



Found with the preceding fossils, in hard calcareous rock. It is 

 well represented by a species from Maestricht, delineated in Faujas, 

 pi. 39, fig. 3, who calls it a Gorgonia. Dr. Goldfuss figures a spe- 

 cimen of the same fossil, pi. 9, fig. 12, also from Maestricht, to which 

 he gives the name of Retepora clathrata. 



CARYOPHYLLIA. Lam. 



Found, though rarely, in the blue marl of Gloucester county, N. J. 



ALCYONIUM. 



Occurs in the green sand below Annapolis, in Maryland. A fossil 

 which I believe to belong to this family, is of frequent occurrence in 

 the calcareous beds of New Jersey, and has also been found in blue 

 marl at St. George's, in Delaware. It most resembles some specimens 

 figured by Mr. Webster in the second Vol. of the Transactions of 

 the Geological Society of London.
