Utica formation at Point a Pic. No new species are named, but a rep-

S. W. Ford (88) comments upon certain fossils discovered in Quebec. 

 The fossils were sent the author by A. R. C Selwyn, director of the 

 Canadian Survey, and the study of them indicates to the author a 

 horizon equivalent to the "Levis" formation of the Canadian geolo- 

 gists. 



Charles Lapworth (143,145) gives an account of some Graptolites dis- 

 cox^ered in Kicking Horse Pass, Manitoba, British Columbia, and on 

 the south side of the St. Lawrence and on the north shore of the island 

 of Orleans, and from near Quebec.

In Part iii of the same bulletin (81) he describes the Bryozoa [Poly-

 ured and described, and the following new species are named, described,

 E. O. Ulrich.)
