 posterior margin. 



" The certainty that the specimen is of Lower Silurian age is 

 therefore shattered ; it may be that it is Upper Silurian and in 

 this case it would be according to your view about Niagara. The 

 Orthoceras is unfortunately not diagnostic." c. s. 



5. Devonian Fauna of Kwataboaheg an River ; by William 

 Arthur Parks. Rept. Bureau of Mines, 1904, Pt. I, pp. 180- 

 191, pis. 1-8. — This paper is of much importance because it gives 

 one a clear understanding of the facies of the Devonian fauna 

 found on the west side of James Bay, heretofore a rarely visited 

 region. The reviewer has elsewhere discussed this fauna, and 

 before Professor Parks's much larger list was made known (Amer. 

 Geol., Sept., 1903, pp. 153, 154). He then stated that the "fauna 

 as listed by Whiteaves shows unmistakably that their age is 

 about that of the Corniferous (Onondaga)." 



The reviewer has enjoyed the privilege of studying the collec- 

 tion belonging to Professor Parks ; hence some of the species 

 here cited appear under other names than in the work reviewed. 

 The following list is not complete, only the more significant 

 species being mentioned : Syringopora, nobilis, S. perelegans, S. 

 kisingeri, I)iphyph.yllum simcoense, Phillipsastrwa (?) gigcts, 

 P. (?) verneuili, Crepidophyllum archiaci, Favosites basaltica, 

 F. hemisphwricus turbinatus, Romingeria umbellfera, Ilelio- 

 phyllum exiguum, tStropheodonta demissa, S. crebristriata, Stro- 

 phonella ampta, Chonetes lineata, Spirifer grieri, S. unicus (the 

 Onondaga form of the Oriskany S. arenosus), Meristella nasuta, 

 Atrypa reticularis, Amphigenia elongata undulata, Conocar- 

 dium cuneus trigonale, Callonema bellatulum, Platystoma linea- 

 tum, Pleurotomaria lucina, Bellerophon pelops, Orthoceras tan- 

 talus, 0. thoas, Calymmene platys, Dalmanites archiops, D. 

 (Synphoria) stemmatus (an Oriskany species), and Phacops cris- 

 tata. 



The author states : " It would also appear that the organisms 

 denote an age comparable with the bottom of the Upper Helder- 

 berg. In some cases the assemblage would denote the Oriskany." 

 These conclusions are undoubtedly correct, for the Onondaga as 

 t<een about Decewville, Ontario, has a large percentage of Oris- 

 kany species, but has not Spirifer unicus. The latter, however, 

 occurs in the Onondaga not far to the southeast, in Erie county, 

 New York. In general the James Bay Devonian holds the hori- 

 zon of the Onondaga and has many of the diagnostic species of 

 the Schoharie grit and Onondaga, and at least one of the very 

 characteristic Oriskany brachiopods. 



The former conclusion of the reviewer " that the faunal facies 

 is more that of the Mississippian type than an y other known " is, 

 through this collection of Professor Parks, brought into closer 

 and more decided harmony with the typical Onondaga of New 

 York. It is clearly established that this fauna did not continue 

 westward into the Manitoba- Athabasca region, as here are known
