39- Asaphus, sp. cf. A. megistos, Locke. 



40. Ceranrus pleurexanthemus, Green. 



41. Phacops Brongniarti, Porllock, or a very closely related 

 species. 



42. Microdiscus ? ? sp. indt., or gen. nov. A very diminative 

 form of trilobite occurs with Nidulites fdvus ? Salter, and Remopleuriies 

 sp. No. 1. It is more closely related to the genus Microdiscus. 



43. Trinuc/eus concentricus, Eaton. Very fine and numerous 

 examples of this typical Trenton species occur in Mr. Weston's collec- 

 tion. These are precisely like those which occur at Montmorency 

 Falls, above the Falls, near Quebec. 



44. Trinucleus, sp. indt. A much smaller but prolific form of 

 this genus occurs with many of the foregoing species. It differs from 

 the other chiefly in size, in being strongly tuberculated and in other 

 subordinate characters. Head and pygidium four millimetres and 

 scarcely four, respectively. 



45. 71/anus, sp. 



Note. 



(a.) Besides the above there appear to be indications of the 

 presence of such forms as Agtiostus, Stauroap/ia/us, Dictanopora, and 

 numerous fragments of crinoidal and cystidean remains. 



(/>.) It may not be uninteresting here to note the discovery made by 

 Mr. Weston this summer, in the rocks on Valier street, Quebec city 

 viz. a portion of a large crinoidal column eight millimetres in diameter. 

 A length of 7.5 mm. of the column is preserved. 



This specimen strongly resembles similar crinoidal fragments sent 

 to Mr. Whiteaves, of the Geological Survey, in 1882, and belonging to 

 the '' Wappinger limestone " of the vicinity of Poughkeepsie, N.Y. 



(r.) It will thus be seen, that so far, from the interesting collec- 

 tions made by Mr. Weston in 1877, 1892 and 1894, respectively, we 

 have no less tha.11/orty-Jive species of fossil remains. These will, no 

 doubt, be supplemented by new and in such cases, probably better 

 specimens, so that this preliminary report will probably be superseded 

 before very long. A great deal of credit is due Mr. Weston for his 

 perseverance in the work he has accomplished, and the present paper 

 brought out in connection with the announcement of this discovery by
