28 VERBILL, SYNOPSIS OP 



spongy. Surface beneath, even, uniformly covered with loose 

 irregular papillae, with large, irregular pores between, pro- 

 ducing a spongy appearance. 



Height of a large specimen 10 inches; width 14; thick- 

 ness 1 inch from edge .3 ; diameter of medium sized cells .09. 

 This is a much thicker and firmer species than T. cinerascens 

 which it resembles. It has deeper, more crowded, and less 

 prominent cells, which are placed less obliquely. The lower 

 surface does not present undulations corresponding to the 

 corallites near the edge, due to the thinness of the coral. 



TUBBINARIA Sp. 



A fragment, too imperfect for identification, of an en- 

 crusting species. Corallites tumid at the base about a line 

 in diameter and elevated nearly as much above the ccenen- 

 chyma, which is strongly granulated.

Corallum turbinated, enlarging gradually from near the 

 base which is broadly attached. Epitheca well developed 

 rising to within about an eighth of an inch of the summit ; 

 above this the wall is very porous and openly granular with 

 deep intercostal furrows. Calicle deep, broadly oval, the 

 depth more than half the greater diameter. Septa in four 

 cycles, the primaries and secondaries considerably exsert, 

 within nearly vertical, with entire inner edges, somewhat 

 falcate and narrowed near the top, where they become gran- 

 ulated, porous and finely toothed, those of the third cycle 

 very narrow and small ; those of the fourth cycle well de- 

 veloped, very thin and porous with jagged edges, the two in 

 each half system meeting each other near the columella, to 

 which they extend. Columella formed by a group of styli- 

 form processes.
