fishes summarized by Whiteaves in the work referred to, embracing in 

 addition to his own accounts descriptions by Doctors Traquair and A. S. 

 Woodward. 



It may be noted that the species at the two localities cited are not 

 the same and Sir William Dawson, who studied the terrestrial plants 

 occurring in these beds arrived at the conclusion that the Scaumenac beds 

 were the equivalents and continuation of the upper part of the Gaspe sand- 

 stone while the beds at Campbellton were identical with the lower part of 

 that formation." 



Remains of Pterygotus and minute holostomatous Valvata-like gastro- 

 pods which, in lack of more exact knowledge, have been called Cyclora 

 (C. valvatiformis and C. turbinata Whiteaves) occur at Campbell- 

 ton, The evidence is in entire accord with the conviction already often 

 expressed that those beds are still the lagoon deposits which inaugurated 

 and characterized the period of the Gaspe sandstones. 



St Helen's island, Montreal. Logan indicated the Helderbergian age 

 of the limestone masses which are supposed by him to represent much dis- 

 turbed lenticular strata " lying in or under the conglomerate " composing 

 most of this island and resting on Utica shales. The fauna has been 

 recently and clearly analyzed by Schuchert who concludes in reference to 

 the structure of the island as a whole that the disturbance of the H elder- 

 berg strata antedates the deposition of the conglomerate which contains 

 blocks carrying species suggesting a middle Devonic age, though these are 

 few and none too certain in their indications. The Helderberg fauna here 

 cited by Professor Schuchert is as follows. 



Rhipidomella cf. musculosa Hall 



Stropheodonta varistriata var. arata Hall 



Rhipidomella cf. oblata Hall
