N. A. INVERTEBRATE PALJiONTOLOGY. 715 



Commimicated to the Eoyal Society of Canada at its meeting in Ot- 

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

 chia 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.

 from the Cambro-Silurian rocks about Ottawa.

Notes the discovery by Messrs. H. Hollick, 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 

 fossils are insufficient for proper determination. Similar fossiliterous 

 sandstones occur on the beaches about Glen Cove, Long Island, and 

 vicinity.

American as well as European forms are discussed in this review of 

 Palaeozoic insects. Some new forms are named, but they are all from 

 Conimentry.
