1. From the Banks of the Red River, in the Parish of St. 

 Andrews, Manitoba. 



ReceptacuUtes Oiceni, 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 '' Report on a Geological Survey of Wisconsin, Iowa and 

 Minnesota." According to Professors Hall and Whitney 

 {'' Geology of Wisconsin, 1862," vol L, p. 429) R. Oiceni '' is the 

 common and abundant species of the Lead region and the one 

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

 the lead- bearing rock." 



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

 which was originally described from the Hudson River 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 largo, 

 hemispherical, or possibly sphoeroidal coral, apparently allied 

 to Monotrypa undulata Nicholson, but too imperfect to allow 

 the whole of its specific characters to be ascertained. To 

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

 sphaerical 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,
