careous sandstone. Fossils are to be found in place also in the exposures 

 under the hit^hway just back of the Robin-Collas fish houses and loose all 

 along the south shore of the basin from Cape Ramsay for a distance of 3 

 miles up the York river. Blocks of a compact quartzite carrying entire

 gaspe n sis are found on the Northwest Arm, four or five miles above 

 the Basin. From the hills in the rear of Gaspe village, presumably the 

 localities which have supplied our material, Barlow collected species in 

 1883, listed as follows by Ells, (1884).

Strophomena blainvillii Spirifer gaspensis 



Chonetcs melonicus Grammysia canadensis 



[Chonetes canadensis] ? Tentaculites 



Leptocoelia flabellites Orthoceras 



No other fossil-bearing localities readily accessible from the coast are 

 known but in the upper reaches of the York river Logan found such 

 calcareous bands with marine fossils at points which seem not to have been 

 since visited for their fossil contents. He says: 



At the mouth of the Patawegia brook, joining the York river on the 

 left bank, about 3 miles above the lowest exposure of limestone, a 6 foot 

 band of this kind occurs in a great thickness of crumbling arenaceous shale, 

 also holding fossils. Among those which characterize the whole exposure 

 are Zaphrentis, Orthis, Strophomena, Chonetes, Rensselaeria 

 ovoides, Leptocoelia flabellites, Avicula, several species of 

 Acephala of undetermined genera, Orthoceras and Dalmanites. Undeter- 

 mined species of .Spirifer and Cyrtodonta are common in similar strata on 

 Silver brook ; and loose fragments of calcareous sandstone, containing some 

 of the above fossils, are found on the surface between the York and 

 Douglastown rivers, south of the lowest exposure of limestone. 



These localities are 20-25 miles in from Gaspe Basin. The position of 

 the calcareous sandstones appears to be near the bottom of the entire 

 series. This inference is largely deduced from the attitude of the strata 

 containing them in Gaspe mountain, for this mountain is a truncated anti-
