﻿Description of Three Species of Fossils. 



21 



some of them a stellate appearance. On the general surface are 

 shown distinct circular or elongate papillae, about l-20th of an inch 

 apart more or less. No oscula or surface pores of any kind ob- 

 served. 



A microscopic section shows an irregular porous structure of the 

 interior ot the body. 



The specimen used for this description is 2J- inches long, slightly 

 arched on one side and nearly straight on the opposite side; Jths of an 

 inch in diameter at one end, 1 inch in the middle, and J an inch at 

 the other end; l-10th of an inch in thickness from the outer surface to 

 the hollow part. How much longer the specimen may have been is 

 not known, as both ends have a fractured appearance. 



Loaned to the writer for description by Prof. R. H. Holbrook, of the 

 National Normal University, Lebanon, Warren county, Ohio. Found 

 near Morrow, in the same county, in the shaly beds of the Cincinnati 

 Group. 



Genus Fistulipora, McCoy. * 



Fistilupora oweni, sp. nov. James. 



The corallum of this species grew, apparently, in a very irregular 

 manner, no definite form or outline, from l-10th to l-20th of an inch in 

 thickness; in flattened, twisted expansions, sometimes spread out in 

 a lobate form, in other cases anastomosing frequently, and again form- 

 ing subcylindrical tubes and projections with narrow or hollow spaces 

 — the hollows and spaces mostly filled with clay. The corallites 

 spring from a base covered with a very delicate striated epitheca 

 (see fig. 2c/). Surface occupied with eight to ten circular tube aper- 

 tures to 1-1 Oth of an inch, which project conspicuously above the gen- 

 eral surface, and show a tendency to an arrangement of five to ten in 

 curved or straight rows sometimes, in other cases placed irregularly. 

 The projecting tubes stand at right angles with the general surface, 

 each tube distinctly separate from other tubes; walls of tubes com- 

 paratively thick on one side, but thinning and sloping to the opposite 

 side (see fig. 2c). Distributed over the surface are maculae having a 

 stellate appearance, about l-10th of an inch apart, and l-20th of an inch 

 across; the maculae are generally somewhat depressed; the interstitia 

 spaces, as well as the maculae, are occupied by more or less small 

 pores, but not so numerous as shown in the tangential section. The 

 surface of weathered specimens appear quite different from perfect 

 unworn examples (see fig. 2 c).
