APPENDIX I. 49 C 



The few fossils collected on the banks of the Churchill, from localities 

 Nos. 5 and 6, are insufficient to establish the exact age of the rocks in 

 which they occur, but it is probable that both are referable either to 

 the top of the Trenton Limestone or to the lower part of the Hudson 

 River group. 



7. From Stony Mountain, Manitoba. 



In 18*75 Mr. E. W. Ells made an interesting collection of fossils from 

 this locality f on behalf of the Survey, which has not hitherto been 

 reported on. Stony Mountain, it may be mentioned, is a hill some 

 fifty feet in height, on the western bank of the Eed Eiver, not far from 

 Fort Garry. The species obtained by Mr. Ells are as follows : — 



Chcetetes delicatulus, Nicholson. Two specimens. 



Monticulipora, Sp. One good example. This is the common Trenton 

 and Hudson Eiver species which Mr. Billings identified with 

 Stenopora fibrosa, Goldfuss. It is also the coral figured by Frof. 

 Hall on Plate 24, figures 1 g, h, i. (cost, excl.) of the first vo- 

 lume of the Palaeontology of New York, as one of the forms of 

 Cluetetes lycoperdon, Say. Dr. H. A. Nicholson places the coral 

 represented in these figures among the synonyms of Chcetetes 

 Fletcheri, Edwards and Haime. In 0. Fletcheri, however, the coral- 

 lites are said to be rounded or oval, with comparatively thick 

 walls, whereas in the present species the corallites are clearly 

 polygonal, with thin walls. 



Monticulipora {Diplotrypa) Whiteavesii f Nicholson. Two small speci- 

 mens growing on the shells of brachiopoda. 



Favosites prolificus, Billings. A fine large specimen, identified and 

 labelled by Mr. Billings himself. 



Streptelasma corniculum, Hall. Several well-preserved examples of a 

 rather small Streptelasma, with a well-developed and smooth 

 epitheca, precisely similar to the small individuals of S. corni- 

 cula figured by Kominger. These Stony Mountain Streptelasmce 

 represent the Hudson Eiver group coral commonly referred to 

 S. corniculum, rather than the typical form of that species from 

 the Trenton Limestone. 



Crinoidal Stems. Detached joints only. 



Ptilodictya {Stictopora) acuta, Hall. A few characteristic fragments. 



Strophomena nitens, Billings. Eight perfect examples of an entirely 

 smooth form of this species. 



Strophomena Hecuba, Billings, One dorsal valve,
