some of which were immediately recognized as being characteristic 

 Trenton forms. Dr. Selwyn arriving in the city at that time, accom- 

 panied me to this locality, and several new species were added to our 

 former collection. 



In conjunction with this paper will be found a list of the genera 

 and species of fossil remains determined by Dr. H M. Ami, of the 

 Survey. It will be readily seen from the lists prepared that a good pro- 

 portion of them are common Trenton forms a gratifying circumstance 

 to the Director of the Geological Survey of Canada Dr. Selwyn who 

 was the first to recognize the Quebec city rocks as a portion of the 

 Trenton zone, and not Levis, as originally supposed. 



However, as the formation under consideration contains large 

 boulders of dolomitic limestone, which were evidently derived from the 

 Levis limestone conglomerates, in which we may find Levis fossils in 

 the shaly portion of the cliff, as in the shales and limestones at the 

 back of the St. John street (Montcalm) market, we must not take the 

 whole as typical Trenton, but as a mixture of Trenton, Utica, and 

 Hudson River.

NOTES ON FOSSILS FROM QUEBEC CITY, CANADA. 

 By Henry M. Ami, M.A., F.G.S., &c. 



The environs of Quebec city have long been regarded as classic 

 ground to the student of North America Geology. 



From the numerous rock-formations around the city, some of the 

 most interesting and important specimens were obtained by various 

 members of the Geological Survey staff, under the ' old regime ' and 

 under the present administration. 



The faunas entombed in the rocks of the so-called ' Quebec 

 Group' at Point Levis and elsewhere, have been described by Billings, 

 Hall, and other palaeontologists. Strange to say, however, for some reason 

 that cannot be accounted for, the sedimentary rocks forming the Citadel 

 Hill and massif of Quebec city, remained for a very long time a tetra 

 incognita. It is only during recent years, that the veil has been
