Dawson, G. M. Note on the Occurrence of Foraminifera, Cocco- 

 liths, &c. in the Cretaceous Eocks of Manitoba. Canad. Nat. 

 n. scr., vol. vii. pp. 252-257. 

 Some Cretaceous rocks from Pembina Mountain were found to re- 

 semble the so-called " chalk " of Nebraska. The greater part of the 

 rock contained shells (Inocerami and oysters) in a " soft whitish earthy 

 matter," which microscopic investigation proved to consist of Forami- 

 nifera, Coccoliths, and allied organisms. The forms described and 

 figured are Textidaria glohulosa, T. pygmcea; Discorhina glohtdaris; 

 Planorhulina Ariminensis ; and various forms of Coccoliths and HJiah- 

 doliths. R. B. N.

The Eugosa are divided into two classes, I. containing the ZapTi- 

 rentidce and the Cyathacconidce ; II. the CyatliopJiyllidce, Monoastrceidce, 

 Bisastrceidce, and Polyastrceidce. Among the Tabulata, the Heliolitidce 

 must be looked upon as the ancient representatives of the recent Mil- 

 leporidce; and the latter are Hydrozoa. The Syringoj^oridce with the 

 incrusting Thecostegitidce and the creeping Aidoj^oridce, which con- 

 stitute the Zoaniharia tuhvlata, may correspond either to Eryozoa of 

 the groups of the Hip>pot1ioidcB and of the Idmoneidce, or to tubuliporous 

 Alcyonaria. The Chcetetidce are closely allied to the Jurassic Hetero^ 

 pora and to the Cretaceous Radiopora. The Favositictce present similar 

 affinities to the tubuline Bryozoa. The Dendroporidce would come 

 near to the Hornera type of Bryozoa. The Fenestrellidce would thus 

 be no longer isolated. G. A. L.
