the branches, that striated epitheca was preserved. This ap- 

 pars to be very rare. In the chert it escaped my notice in 

 this instance, and out of several scores of specimens obtained 

 I can only recall two cases where it was preserved. Dr. Jas. 

 Hall, who founded "The Genus" and described it as "a Coral 

 composed of a series of tubes, or cells, radiating equally on all 

 sides from the axis, and apparently destitute of septa, or rays. 

 This corresponds with its general appearance here, when the 

 epitheca was not preserved. Indeed, then, it resembles a 

 branching "Chetaetes," or "Monticulipora," rather. Nicholson, 

 in "The Palseontology of Ontario," states : We are unable, 

 so far as our specimens enable us to judge, to separate the 

 forms referred to, ''Cladopora," from Favosites. The Pro- 

 fessor's were obtained in Niagara Limestones (two species 

 only, as far as I can see). He was not likely to find either 

 v\'ell preserved in this material, and neither "Hall" or "Nich- 

 olson" mention an Epitheca, so we may infer this feature was 

 unknown to them. Prof. Foorde, former Assistant Palaeontol- 

 ogist Canadian Geological Survey, considered "Cladopora" 

 belonged to "the Monticuliporidas." So you may perceive a 

 difference of opinion exists regarding it. Dr. Ami received a 

 small collection from "the Glaciated Chert," which may throw 

 a little light on this obscure "Family Group." There are sev- 

 eral forms probably undescribed yet. The Chert (flint flakesj 

 near the Corporation Drain presented some fragments of "a 

 Cornulites," which I have not seen figured. Outw^ardly it 

 bears a near resemblance to a dwarfed "Orthoceras." This 

 IS deceptive. Other fragments likewise obtained display nei- 

 ther "Septa" or "Syphencle," but a hollow tube inside, or in 

 some cases, one filled with darker chert ; so no doubt can ex- 

 ist regarding the classification. On the whole the organic re- 

 mains there were disappointing, since the removal of "The 

 Indian Corn" last Autumn, and few rare fossils were found. 

 The same may be said of the Niagara Limestones in our local 

 quarries. They presented merely a few New Graptolites, per- 

 haps.
