Appendix II. — Account of six species op Polyp aria obtained 

 from Timber Creek, New Jersey, and described by William 

 Lonsdale, Esq. F. G. S. 



The following is a list of the species : — 



1. Montivaltia atlantlca Lonsdale ( Anthophyllum atlanticum Morton). 



2. Idmonea contortilis Lonsdale. 



3. Tubulipora Megaera Lonsdale. 



4. Cellepora tubulata Lonsdale. 



5. Eseharina? sagena Z,oMsiia?fi (Fhistra sagena Morton). 



6. Eschara digitata Morton. 



I. Montivaltia atlantica. 



a. Nearly perfect specimen, exhibiting the lamelliferous or upper portion in its 

 true position, and the inferior hollow cone. 



h. Portion of the upper surface slightly worn down, to show the characters of 

 the lamella. 



Inversely conical; lower or non-lamelliferous portion nearly 

 equal in length to the upper or lamelliferous; enveloping crust 

 extending nearly to the superior tertnination of the cone; lamel- 

 liferous portion variable inform; lamellce very numerous; centre, 

 contorted plates terminating inferiorly in a distinct umbilicus or 

 boss ; superior termination of the cone nearly flat. 



This coral is described by Dr. Morton under the name of An- 

 thophyllum atlanticum. (Silliman's Journ. vol. xviii. pi. 1. f. 9, 



10. Essays on Org. Rem. &c., p. 61. 1829. Journal Acad. Nat. 

 Sc. Philadelphia, vol. vi. pi. viii. f. 9, 10. pp. 123, 124. 1830. Sy- 

 nopsis Org. Rem. &c. pi. i. f. 9, 10. p. 80. 1834.) 



Dr. Morton states (Essays, pp. 61, 62. Synopsis, p. 80.) that he 

 derived his characters of the genus Anthophyllum from Goldfuss ; 

 and the lamelliferous portion of the coral under consideration, as 

 represented in Dr. Morton's excellent figures, bears a strong general 

 resemblance to some of Goldfuss's species (Petref. pi. xiii. f. 10, 



11. pi. xxxvii. £ 15.). The fossil is probably generically identical 

 with that represented in pi. xxxvii. f. 15. There is also a general
