488 H. M. AMI — THE GEOLOGY OF QUEBEC. 



forms have been obtained (descriptions of which will, it is hoped, soon be 

 published) : 



Girvanella, sp. und. ; 



Sole)wpora compada, var. mimda (var. iiov.) ; 



Diplotrypa quebecensid (sp. nov.) ; 



Monotrijpa incerta (sp. nov.) ; 



Prasopora lycoperdon, Vanuxera, var. selwyni (var. nov.) ; 



Orthis, allied to 0. testudinaria, Dalman ; 



Leptcena, like L. sericea; 



Asaphus, sp. und. ; an obscure form. 



This peculiar association of forms occurring in such a series of strata will 

 be noted later on. 



Cote de la Negresse. — Farther westward, at Cote de la Negresse, the hard^ 

 compact and fine-grained calcareo-argillaceous aud bituminous bands were 

 seen, associated with bauds of serai-crystalline and somewhat bituminous 

 limestones, quite different in facies from the strata at Cote Sauvageau ; and 

 at the turn of the road up the hill along Richmond street two obscure fossils 

 were obtained, one of which appears to be a CmnereUa or Aiiastrophia, the 

 other a Platystrophia or other coarsely ribbed brachiopod. The strata here 

 dip at an angle of 45° southward. 



Montcalm Market. — Immediately south and again about one hundred 

 yards southwest of ^lontcalm market, in the city of Quebec, we have a series 

 of black bituminous and calcareous shales holding abundance of graptolites, 

 brachiopods, ortracods and trilobites, with bands of thinly bedded limestones 

 aud an occasional hard, cherty, compact, quartz-bearing band, which re- 

 sembles a conglomerate. The strike of the strata here is N. 45° E. (mag- 

 netic), and the dip about 70°, increasing to 78° in some instances. From 

 the exposures north of St. Patrick street aud between the roads leading from 

 that street to the market the following fossils have been obtained :
