INDIANA PALEONTOLOGY. 202. 



elevated space in the bottom of the calix, situated sometimes on the sinistral 

 side and again it may be situated on the dextral side of the tabulae, this may- 

 be due to the curviture of the coral. 



Found in the Middle Devonian, (upper Helderberg group) at the Falls of 

 the Ohio. Now in the collection of the author.

Edwards AND Haime' s DESCRiPTroN : Corallum simple, very long, slightly 

 bent, subcylindrical, provided with a very strong epitheca, and presenting rather 

 strong subhorizontal circular wrinkles. Calicular cavity rather deep, the sep- 

 tal striai, when visible, more distinct towards the outer part of the ealice. Ve- 

 sicules unequal in size, the largest occupying the center of the visceral cavity, 

 and about one line in length. Height of the coral in general about three or 

 four inches. We have seen in the collection of Mr. Pengelly a specimen that 

 measured one foot in length and one and a half inches in diameter. 



The British specimens submitted to our examination were found at Lor- 

 guay, Plymouth and Meedstone Bay. Prof. Phillips has met with the same 

 species at Babbacomlie, and Prof. McCoy at Newton Bushel. It exists also in 

 Spain at Millar, in the Province of Leon; in Germany, in the Eifel mountains: 

 and in America at Corn Island, Falls of the Ohio. 



The illustrated specimens were collected in the upper Helderberg group, on 

 Goose Island, at the Falls of the Ohio. Now in my collection. 



CYSTIPHYLLUM GEMMIFERUM, N. Sp. 



Plate 60. Fios. 3, 4, 5. 



Corallum simple, or composite, increasing by calicular and lateral gemma- 

 tion, with a rough wrinkled scar at the base of attachment. Height forty milli- 

 meters. Corallites unequal in size, from twenty to forty millimeters in diame- 

 ter. Calix oblique, very shallow, not exceeding five millimeters in depth. The
