FOSSILS FROM COTE ST. PAUL. 



In Januar}^, 1906, Dr. Adams sent me some specimens from Côte 

 St. Paul described as follows: 



" Last summer one of my students found at Côte St. Paul, between 

 Montreal and Lachine, a block of limestone of considerable size having 

 a piece of characteristic breccia attached to it, so that it evidently formed 

 part of the limestone inclusions in a l)reccia like that of St. Helen's 

 Island and this limestone contained a large number of fossils some of 

 them clearly of 'Devonian types." 



After breaking up the specimen and examining the fossils, I was 

 also impressed by the close resemblance to typical Hamilton species, and 

 interpreted the fauna as Hamilton, with the following specific identifi- 

 cations : 



Spirifer pennatus, Atwater, the long attenuate variety. 



Choneies coronatus var. syriilis, Conrad. 



Tentaculites hellulus. Hall. 



cf. a fragment of Limoptera, and in a letter reported this opinion 

 to Dr. Adams. I, then believed this to be a confirmation of the Middle 

 Devonian age of some of the fauna of the St. Helen's area and it was 

 only after a very thorough review of the fauna and its comparison with 

 other faunas from the eastern province, that I was able to revise my 

 first impressions, and led to believe that there is here a case of the ap- 

 pearance of forms very closely related to typical Hamilton species at a 

 much earlier age than the Hamilton Epoch. A similar case although 

 reversed has already been demonstrated in New York State where 

 repeated recurrences of Hamilton species have been located later than 

 the income of the typical Chemung formation. As a result of this critical 

 review of the fauna of the Côte St. Paul block of limestone, I now 

 consider the specimens to be more properly described under the follow- 

 ing names: viz. 



1. Spirifer pennatus var. Ilelenœ, var. nov. (H.S.W.) 



2. Choii£tes (Eodevonaria) hudsonicus metatype Gaspensis, Clarke. 



3. 'Çr en m cut it es ScMotlieimi, Koken {cf. elongatus. Hall). 



4. cf. " Avicida textilis. Hall."
