LOCALITIES YIELDING UTICA POSSlLS. 485 



a number of iuteresting collections were made by Dr. Ells, I'Abbe La- 

 flamme, Mr. St. Cyr, Mr. AVestoii and the writer, and the following lists of 

 species have been prepared therefrom. 



Montmorency. — In the soft, brittle calcareo-argillaceous and bituminous 

 shales which are much disturbed and faulted in a position overlying the 

 Trenton limestones of the brook in the ravine at the northern end of the 

 gorge of Montmorency falls were found the following species: 



D iplograptus, sp. und. ; Endoceras 'proteiforme ; 



Climacograptus, sp. und. ; SerpulUes dissolidus ; 



Orthograptus quadrlmucronatus ; Triarthrus hecki. 

 Leptobohis insignis; 



Between the steps leading from the top of the gorge on the eastern side to 

 the foot of the falls and the lower point, the following species were collected 

 by the writer : 



Orthograptus quadrlmucronatus (?) ; Climacograptus, sp. und. ; 

 Reteograptus eucharis ; Triarthrus hecki. 



Beauport. — Leaving thefUtica at the foot of the ftills (much disturbed 

 and faulted between the steps and the cliff at the northern end of the gorge) 

 and the more evenly bedded and inclined strata south of the steps to the 

 lower point, and proceeding westward to Beauport, the Utica is again seen 

 at this point. Near the shore, I'Abbe Laflamme obtained a large slab of 

 shale on which were seen a Climacograptus, sp. und., several examples of the 

 typical Leptobolus insignis, Hall, and Triarthrus hecki, Green. 



At Parent's quarries, a little further northward, the Utica shales were 

 examined by Mr. St. Cyr, and the following species obtained : 



Schizocrania filosa ; Endocerus proteiforme ; 



Leptcena sericea ; Asaphus canadensis 



Lyrodesma pidchellum ; {= Asaphus latimarginatus). 



The above species are now in the museum of the Department of Public 

 Instruction, Quebec. 



Charlesbourg. — About fifty paces south of the Charlesbourg church the 

 Utica is exposed along the main road. It dips at a considerable angle to- 

 ward the south, varying in intensity from north to south from a few degrees 

 to nearly fifty degrees. The rock here is a brownish-gray calcareous shale, 

 from which the following species were obtained : 



Climacograptus or Diplograptus ; Bellerophon hilohatus; 



Leptograptus (J) flaccidus; Primitia lUrichi (?) ; 



Leptoholus insignis; Triarthrus hecki. 

 Strophomena, sp. und. ;
