 Several specimens from the dolomite at Rochester and the upper 

 Guelph at Oak Orchard creek differ materially from other species in size of 

 the corallites, and, while they are uniform in this regard, they vary among 

 themselves. They form depressed, hemispheric or flat, though massive 

 expansions. The cells vary from .5 mm to 1.5 mm in diameter, and are 

 prismatic. Long septal spines, reaching nearly to the center of the cor- 

 allites, are arranged in longitudinal rows. The number of rows of pores 

 has not been positively determined. The tabulae are thin, flat, horizontal, 

 closely arranged, from .5 to i mm apart. 



This form is well known from the Niagaran and Guelph formations 

 and has a wide distribution.

With this species has been identified a fragment of a very coarse type 

 of Favosites from Rochester. The calyxes of this specimen average
