Mr. Andrew Halkett, of the Marine and Fisheries Depart 

 ment, then read his paper "On Gannets and Cormorants, with 

 Special Reference to Canadian Forms." This paper was full of in- 

 teresting- notes of observations made in the field and along- the 

 shores of the Atlantic and Pacific in British North America. 



(i) '■'■ Noie on the Occurrence of Ranopleu rides in the Upper 

 Trenton ( Ordovician) of Parliament Hill, Otta%va, ( anada'' ; (2) 

 " On a new species of Turrilepas f/om the Trenton limestone of 

 Goverfior's Bay, Ottawa, Canada,^' are the titles of two brief papers 

 presented by Mr. H. Ami, in which he give descriptions of two 

 species supposed to be new to science. The first was a trilobite 

 from the Upper half of the limestone beds of Parliament Hill, 

 Ottawa, whose affinities came close to Ranoplettrides Canadensis, 

 Billings, described from the Chazy of the Township of Clarence, 

 some 500 feet lower down in the series of Ordovician strata in the 

 Ottawa Valley. 



The other was a ' barnacle ' or cirripede from Governor's 

 Kay, of which one of the small opercular values was discovered on 

 on the occasion of one of the Club's Excursions last April, 1899. 

 Its nearest ally is Turrilepas Canadensis, Woodward, from the 

 Utica of Gloucester, opposite the Old Rifle Range. Mr. Ami then 

 drew the Club's attention to Prof. W. H. Hobb's interesting paper 

 " On the Diamond-field of the Great Lakes " and gave an abstract 

 of its contents, illustrating his remarks on the discovery of the 

 eight diamonds in Wisconsin, Ohio and Michigan glacial gravels 

 by means of lantern slides in which the probable source of the 

 glacial drift of three states was traced to Canada from the detritus 

 brought down by the Labradorean or Keewatin glaciers or both. 



'■''Principal Places of Geological Interest about Ottawa" was 

 then discussed by the President and illustrated by means of 

 lantern slides. Dr. Fletcher, Messrs. A. W. Brock, R. B. Whyte 

 and others took part in the discussion which followed the reading 

 of these geological papers.
