branches characteristic of a different form, Dictyonema. In 

 this case it appears to your collector that the mistake in 

 nomenclature originated, perhaps, as much from impaired 

 vision as carelessness on his part. It certainly seems 

 unexcusable when previously he pointed out the distinguishing 

 marks of the family itself, which stared him in the face when 

 represented in our Proceedings. Absolute accuracy is very 

 properly required by all Geologists where matters are 

 submitted for investigation, and here we must regret the 

 deficiency. No doubt the mistake can easily be rectified by 

 any Palaeontologist who takes an interest in our local Niagara 

 Graptolites. 



Again it may be necessary to remind the Council of the 

 Association that the Geological Section recently heard from 

 Ottawa that the collection of Bryozoons from Hamilton and 

 Grimsby had been forwarded to Dr. Brasler at the Smith- 

 sonian Institute at Washington — a scientist who has made a 

 particular study of these early and neglected Silurian fossil- 

 organic remains. The names given to new species, if such 

 have been recognized, are to us as yet quite unknown. Dr. 

 Jas. Hall's Genera Lichenalia undoubtedly presents a larger 

 number of Chert species than was ever supposed to be obtain- 

 able on this continent. When the Bryozoons were submitted 

 to the Smithsonian expert, Professor Brasler, for examin- 

 ation, a considerable number of the class in question were 

 discovered. Some differ, at least in shape or form, from 

 others previously obtained. Professional Palaeontologists 

 who make a particular study of these little-known Silurian 

 organic remains, are, as far as I can see, most competent to 

 name and describe the various specimens displayed in our 

 local rocks of the district. 



In a recent paper I alluded to the extraordinary number 

 of fossils discovered in the Niagara glaciated Chert beds of 

 Dr. Jas. Hall's Cladopora. Dr. Spencer recognized a single 

 specimen rightly attributed to a similar one occurring in the 

 United States. The recent discoveries here were quite 

 unknown then to either Dr. Jas. Hall or Dr. Spencer. If a
