N. A. INVERTEBRATE PALAEONTOLOGY. 715 



Communicated to the Royal Society of Canada at its meeting in Ot- 

 tawa, May, 1885. Sir William Dawson describes the new species Wal- 

 ehia imhricatula from the Trias ; Sir William concludes that Mr. Bain's 

 lower series is distinctly permo-Carboniferous ; that its extent is con- 

 siderably greater than was supposed in 1871 ; that there is a well char- 

 acterized overlying Trias, and that the intermediate series, whether 

 Permian or Lower Triassic, is of somewhat difficult local definition; but 

 that its fossils, so far as they go, lean to the Permian side.

Notes the discovery by Messrs. H. Ilollick, W. T. Davis, and himself 

 of fossil leaves in the Cretaceous clays at Kreischerville, Staten Island. 

 The specimens were obtained from a stratum of lignitic clay about 18 

 inches in thickness, and included angiosperms and conifers.

 Dr. Britton considers the sandstones of Cretaceous age, although the 



fossds are iusufQcient lor proi)er determination. Similar fossiliferous 



sandstones occur on the beaches about (ilen Cove, Long Island, and 



vicinity.

Palneozoic insects. Some new forms are named, but they arc^ all from
