1. From the Banks of the Eed Eiver, in the Parish of St. 

 Andrews, Manitoba. 



Recept acuities Oweni, Hall. (=Coscinopora sulcata, D. D. Owen, non 

 Goldfuss.) A fine specimen, which, when perfect, was probably 

 at least one foot in diameter. The occurrence of this species at 

 Lower Fort Garry (which'is in the parish of St. Andrews) was 

 first placed upon record by D. Dale Owen in 1852, on page 181 

 of his " Beporton a Geological Survey of Wisconsin, Iowa and 

 Minnesota." According to Professors Hall and Whitney 

 ("Geology of Wisconsin, 1862," vol I., p. 429) R. Oweni "is the 

 common and abundant species of the Lead region and the one 

 known as the ' lead-coral,' from its constant association witn 

 the lead-bearing rock." 



Favosites prolificus, Billings. A characteristic fragment. This species, 

 which was originally described from the Hudson Eiver group 

 of Anticosti, occurs also, as will be shewn further on, in rocks 

 of the same age at Stony Mountain, Manitoba. 



Halysites catenularia, Linn. One good specimen. 



Monticulipora (Monotrypa), Sp. Indt. A fragment of a rather large, 

 hemispherical, or possibly sphceroidal coral, apparently allied 

 to Monotrypa undulata Nicholson, but too imperfect to allow 

 the whole of its specific charactei*s to be ascertained. To 

 the naked eye the specimen appears as a portion of a henii- 

 sphserical crust, about three-quarters of an inch thick in the 

 thickest part and half an inch in the thinnest. The convex 

 and presumably upper surface is almost covered with small,
