end. The corallites radiate from the central object, and have a slight 

 upward inclination at first, then curve directly to the outer surface. 

 Slightly raised, rounded monticules, about one line apart from center to 

 center, irregularly distributed over the surface, occupied by calices some- 

 what larger than the average. Margins of cell apertures thin and sharp: 

 no interstitial tubes observed. Calices polygonal and averaging about 

 eight to ten in the space of one line. 



A microscopic section of the interior shows the tubes to be thin-walled 

 throughout, of a somewhat duplex character, and very few, remote, 

 indistinct tabulse. In tangential section the cell walls are angular : no 

 spiniform corallites noticed. 



The specimen used for this description is seven inches long, over two 

 inches in diameter at the thickest swelling, and one half to three fourths of 

 an inch at the narrowest constriction. 



Found by Dr. T. D. Dyche, in company with the writer, near Leb- 

 anon, Warren Co., O. Cincinnati group. 



Named in honor of the discoverer. 



CORRECTIONS. 



Pleurotomaria, sp. carinata, James. On page 12 Pal.., this species is 

 described as resembling sp. dry ope, Billings. Further examination of 

 additional examples, since collected, show it to be distinct. 



Modiolopsis, sp. oblonga, James. This specific name proposed in place 

 of siibspatulata (see Pal. page 23), pre-occupied by one of Prof. Hall's 

 species. 



Plumulites, sp. Jamesi, Hall & Whitfield, wrongly placed in the cata- 

 logue, p. 6, No. 161. See correction on page 12 of catalogue, No. 365^. 



Anomalocystites — Enoploura. Dr. Henry Woodward {Geological 

 Magazine., May, 1880) decides that Prof. Meek .was not in error in describ- 

 ing species balanoidcs under the Genus Anomalocystites., as stated by 

 Prof. A. G. Wetherby {Journal of the Cin. Soc. of Nat. Hist., Jan. & 

 July, 1879), and that he (Prof. W.) was wrong in removing the species 

 to his new Genus Enoploura, which seems now to have no foundation, 

 and naturally drops out of sight.
