This species is mentioned by Professor H. AUeyne Nicholson, in his 

 second Report on the Palaeontology of Ontario, as having been found at 

 Hespeler, but it is not included in any of the lists of fossils from the 

 Guelph formation in the " Geology of Canada," and the writer has failed 

 to recognize it in any of the later collections received by the Survey.

Gait, Dr. R. Bell, 1861 ; Hespeler, T. 0. Weston, 1867 ; Elora, Dr. R. 

 Bell, 1861, T. C. Weston, 1867, and D. Boyle, 1880; Durham, J. Towns- 

 end, 1878-82. Most of the specimens from these localities are so highly 

 dolomitized that the more minute internal structures of the corallites are 

 obliterated, but the spiniform septa are well preserved in a specimen from 

 Lot 16, Concession 1 of Bentiok, and the mural pores in specimens from 

 Durham. 



In the Geology of Canada (1863) P. Hisingeri is recorded as occurring 

 in the Niagara limestone at Thorold and Drummond Island, also in rocks 

 of about the same age at Port Daniel, in the Bale des Chaleurs. It has 

 recently been recognized by Mr. L. M. Lambe in collections made by Mr. 

 James Richardson, in 1856, at the Jumpers and Cormorant Point, Anti- 

 costi, and by Mr. T. C. Weston, in 1865, at Wall's Cove, Anticosti.

The corallites of the few specimens of a Favosite with a branching 

 corallum that the writer has seen from the Guelph formation at these and 

 other localities in Ontario, are polygonal, unequal in size and thin walled. 

 These specimens clearly do not belong to the genus Pacliypora and their 

 specific relations are obscure. They are here provisionally referred to F. 

 polymorpha in accordance with the identifications of Billings and Nichol- 

 son.
