prefer to designate it. Dr Ells has recorded the same occurrence and 

 states ' that the strata here " are very near the contact with the rocks of the 

 Quebec group and the fossils are from the lower division of the limestone 

 series." In the short section there presented we find at the base heavy 

 beds of quartz conglomerate ("Quebec"?) followed above by arenaceous 

 limestones and over these more schistose limestones. Both of the latter 

 carry fossils which unquestionally pertain to the fauna of the St Alban 

 bed? and are quite devoid of characters which would closely ally them to 

 the higher or Grande Greve fauna. 



Some of the beds in this Griffon Cove river section, which we may not 

 have seen, Logan regarded as the summit of the Gaspe series, and we may 

 therefore specify that those examined by us and from which the fauna here 

 cited was obtained are in the vicinity of the highway bridge over the river 

 about three miles in from the south shore. 



Fauna of the Si Alban beds 

 Some incongruities appear in the comparison of published lists of the 

 fossils of these beds given by Billings^ and Ami, and those based on 

 the materials we have collected and here described. The differences are 

 more apparent than real and are probably due in part to the fact that those 

 in Logan's work were only provisional and subject to revision, and it is also 

 possible that Messrs Billings and Ami had species which may not have 

 come under our observation. In citing Logan's classification of the rock 

 series we have given the fossils as quoted by him and these we bring 

 together again for purposes of comparison ; in this list comparisons or 

 identities with our own material are suggested [second column].

 by Billings.
