species are given in table No. I on page 118. 

 At the north end of the quarry a few examples 

 of Megalomus are found, but this characteristic 

 genus is not prolific near Guelph. 



The debris thrown from the shallow cuts 

 along the Grand Trunk railway north of 

 Hespeler affords one of the richest and most 

 accessible collecting grounds in the district. The 

 common species are given in column No. 2 of 

 the table on page 118. 



Excellent exposures occur on both sides of 

 the river above and below Gait. A typical 

 section is seen in the Dickson Park quarry, 

 where Megalomus canadensis occurs in great 

 abundance associated with the species given in 

 the third column of the table. 



The quarries of Christie and Henderson, 

 beyond Gait, present a face of about 45 feet 

 (13-7 m.) of both thin and thick-bedded stone 

 characterized throughout by a wonderful pro- 

 fusion of Megalomus canadensis. The species 

 given in the fourth column of the accompany- 

 ing table are common in this quarry.
