1 38 EOCENE AND LOWER OLIGOCENE CORAL FAUNAS. 



Those of the first and second cycle and some of the third cycle fuse in the 

 columella space to form a false columella. Septal faces granulate. Char- 

 acter of the septal margins unknown. Greater diameter of calice/ 

 10 mm.; lesser diameter, G mm. 



Locality. — Eastern Wilcox County, Alabama. 



Geologic occurrence. — Midway bcds, "TuiTitclla rock." 



The external features are well preser\-ed in the specimen above 

 described, so there should be no difficult)' in recognizing the species when 

 found again, but sufficient detail for absolute certainty in the generic deter- 

 mination can not be made out. The species is referred to Astrangia because 

 some species of the genus have a similar habit of growth. Astrangia lineata 

 (Conrad) from the Miocene of Petersburg, Virginia, is a good instance. 

 This is undoubtedly an Astrangia, and among the specimens of it in the 

 United States National Museum instances of exactly the same method of 

 growth as that presented by ^i. wilcoxemsis can be found. This species also 

 may belong to the subgenus Phyllangia M.-Edw. and H. 



A. wUcoxensis differs from A. harrisl in the character of the costiB. 



These differences are brought out in the specific descriptions and in the 



figures.

Tlie following is the original description of Lonsdale: 



Branched; branches variously disposed, nearly cylindricil, outer wall thin, not 

 thickened externally when old, porous, strongly but irregularly ribbed, and marked 

 by lines indicative of renewals of growth; lamella' numerous, unequal, sides foraini- 

 nated and hispid; interstitial lamella' or diaphragms distinct, center a complicated 

 reticulation; branches produced from germs develo[)ed without the area, or on the 

 sides of preexisting stems. 



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

 I saw in the collection of the Geological Society of London specimens 

 from Lonsdale's collection labeled "Eutaw, South Carolina." There are
