Faraily T'O'RITI'DJE Milne-EdAvards and Haime. 



Genus PORITES Link. 



PoRiTES RAMOSA (Lonsdale). 



PI. XXIII, figs. 4 to 6 (fig. 4 reproduced from Londale's figure).

p. 123. 



Branched or lobed, fibers coarse, cylindrical or compressed, intimately reticu- 

 lated; intertibral lacuuie equal in dimension to the fibers; canals numerous, vertical 

 in center of specimen, horizontal toward the exterior, no definite arrangement; form 

 more or less circular, no distinct wall ; lower extremity blended with the fibrous struc- 

 ture, interior sometimes penetrated by converging simple fibers; exterior of specimen 

 partially invested by a thin rugose layer. ' 



Lonsdale considered this coral related to the Cretaceous sponge Ven- 

 triculites, and wrote considerable about the similarity of the two fossils; his 

 observations on this I think will not aid much in identifying the species, 

 so I omit them. 



Localities. — .Jacksouboro, Georgia ; Eutaw, South Carolina. 



I found some specimens of this species in the collection of the Geo- 

 logical Society of London, but not the ones figured by Lonsdale. These 

 specimens came from Jacksonboi'o, Georgia, and are lithologically the same 

 as the one in the United States National Museum. I could not add any 

 special detail from the London specimens. Very little can be added from 

 the one in the United States National Museum. Two drawings from this 

 specimen are shown in PL XXIII, figs. 5, 6. The whole skeletal structure, 

 both coenenchyma and septa, are very perforate. The corallites are 2 mm. in 

 diameter, and are from 2 to 3 mm. apart. There seems to be 10 or 12 septa. 

 This is about all that can be said concerning the characters of the species. 



The matrix is a whitish, rather hard, chalky, argillaceous limestone, 

 and contains, besides the Porites ramosa, specimens of Cladocora recrescens. 



DOUBTFUL SPECIES. 



We either have no clue to the proper systematic position of the following 

 species, or, as in two instances, no descriptions of the species could be 

 found, or they can not be identified for other reasons.
