GUELPH FAUNA IN THE STATE OF NEW YORK 31 



between 2 and 3 mm in width, the tabulae are in the main closely arranged 

 and the cell walls strong ; the mural pores are provided with a distinct rim, 

 as observed by others, are much larger than those of specimens referred 

 to F. n i a g a r e n s i s, are arranged in three rows and set closer together 

 than in other species. The marginal depressions of the tabulae observed 

 in F. gothlandicus by Mr Lambe are also easily observable in this 

 specimen. Septa have not been noticed. The walls of the corallites are 

 striated concentrically in several places, indicating the growth lines. 



To all appearances this is the same form as that described and figured 

 by Hall asF. favosa? Goldf. from the Niagara limestone at Milwaukee 

 [op. cit.~\. F. favosus has been currently considered as a synonym of F. 

 gothlandicus. Whiteaves, Lambe and Milne-Edwards and Haime do 

 not recognize that species.

 Both at Rochester and at Shelby fragments have been obtained 

 which differ noticeably from the other specimens in the small size of the 

 corallites, which average not quite 1 mm in diameter. Interspersed 

 between these are less numerous, almost circular, somewhat larger coral- 

 lites. The walls are rather thin, the tabulae irregularly disposed, the 

 pores apparently arranged in two rows and the interior of the cells pro- 

 vided with horizontal scales or squamulae. 



It would seem to be a specimen of like character that was identified 

 by Nicholson 1 as coming from Hespeler. In regard to the occurrence of 

 this species, Dr Whiteaves remarks that it is not included in any of the 



x Pal. Ontario. 2d Rep't. p. 56.
