ON THE ROCKS OP THE QUEBEC GROUP. 191 



very hard, and in which the fossils occur in layers, marking well the 

 stratification. The limestones split with moderate facility in the 

 direction of those layers, and give considerable planes of surface, 

 with fossils starting prominently up from them. I presume therefore 

 that the beds at the Redoute, with which Mr. Marcou compares 

 the limestones No. 1 and 3, are some which he has not yet 

 desribed, and with which we can make no comparison, as we have 

 not been so fortunate as to find them. 



Since 1860. Mr.Devineand Mr. Cayley, both of the Crown Lands 

 Department, have obtained several species at Point Le'vis. The lat- 

 ter gentleman discovered Amphion Cay leyi, (Billings) in band 3, 

 (A 2 ) on the North Ridge ; and Mr. Devine, on the same ridge, has 

 procured Bathyurus Saffordi from band 2, Menoceph ahis globo- 

 sus, and Cheirurus Eryxhom band 3 (A 2 ) ; and from band 4 (A 3 ) 

 Bathyurus Saffordi, B. Cordai,aud B. bituberculatus. But from this 

 band he has made a very important addition to the fauna of Point 

 Le'vis, in a perfect specimen of what Mr. Billings agrees with him 

 in considering an Olenus, or a closely allied genus. This was ob- 

 tained on the North Ridge, just east of the fief St. Anne, in a mass 

 of drab-colored limestone ; which Mr. Devine thinks is a part of 

 the solid band, although he has not yet tested the matter suffi- 

 ciently to be positive. The same part of this band here holds 

 OboMla, Orthis Evadne, Camerella calcifera, Pleurotomaria, 

 Ecculiomphalus Canadensis, Orthoceras, Agnostus Americanus, 

 A. Canadensis, A. Orion, Arionellus subclavatus, Bathyurus 

 capax, B. quadratus, B. Saffordi, Cheirurus Eryx, C. Apollo, 

 Dikelocephalus magnificus, D. megalops, D. planifrons, D. 

 Oweni, Menocephalus Sedgivickii, and M. Salteri. In this col- 

 lection, the species of Pleurotomaria, Ecculiomphalus, and 

 Chierurus do not occur in the same hand-specimens of rock with 

 the others. Bathyurus Saffordi is in the same specimen with 

 Menocephalus Salteri. On the Middle Ridge he has ob- 

 tained Menocephalus globosus from band 4, at the Redoute. 

 Mr. Billings has obtained in band 2, on the North Ridge, 

 Bathyurus quadratus ; on the Middle Ridge, in band 6, on 

 the north side of the anticlinal, Leptcena decipiens; and the same 

 species in band 7, on the same side of the anticlinal ; while band 

 1, on the south side of the anticlinal, has yielded him a Pleuro- 

 tomaria, allied to P. Laurentina, Orthoceras, n. s., Illamus , 



and Asaphus ■. In a band of conglomerate forming two 



successive mounds at the water's edge, northwest of the Coast
