Fig. 13 — Monticulipora subcylindrica, U. P. James, (n. sp., in MS.) a type specimen, half 

 nat. size ; b longitudinal section, magnified ; c surface, magnified. (Original) 



Corallum irregularly sub-cylindrical, about four and one-half 

 inches long, by one to one and one half inches in diameter, tapering 

 gradually to both ends where it rounds off abruptly : surface with 

 distinct monticules irregularly distributed, about one or one and one- 

 half lines apart and extending even over the ends; calices polygonal, 

 eight or ten in one line, those on the monticules slightly larger than 

 the average : tube walls thin and sharp when unworn; no interstitial 

 corallites : corallites radiating from a central point or a central object 

 directly to the surface, with wavy walls: tabulae numerous, complete 

 and horizontal, apparently as numerous at the centre as at the 

 periphery. 



Locality. — Cincinnati and Morrow, Ohio. 



Remarks. — This description is drawn up from notes left by Mr. 

 James and from the specimen labeled by him. It seems to be a good 

 species and to be well characterized by its mode of growih, the 

 uniform cells, and the close tabulation. The specimen was named in 

 1887, apparently at the time it was found, but the description has 

 never before been published. 



INCERTA SEDES. 



A few species have been described as belonging to this 

 group that are too indefinite to have any place assigned to them,
