Tertiary Fossils of Canada, Sfc, 



either side of the earlier whorls. When seen from one side it 

 resembles Rotalina turgida, for which indeed I mistook it at 

 first ; but when viewed in front it is seen to be equilateral and to 

 have the characteristic septal aperture of Nonionina. It is about 

 ^qual in size to iV. umhilicatula, and has the last chamber 

 inflated even in young shells.

The Foraminifera from the deeper parts of the Gulf are usually 

 of small size, and this applies also to those from the pleistocene 

 of Labrador. 



In the past summer another deposit of pleistocene shells was 

 discovered by Sir W. E. Logan at the Mingan Islands, Labrador. 

 The specimens obtained from it consist of 3Iya arenaria and 

 Tellina proxima in hard sand, and have the aspect of a littoral 

 deposit corresponding to the " saxicava sand" of the vicinity of 

 Montreal. 



2. Portland, Maine. 



In last August I enjoyed some opportunities of examining 

 the tertiary deposits at and near Portland, and also at Pond Cove, 

 Cape Elizabeth, where a small patch of this deposit occurs nearly 

 at the level of the sea. At the south end of the city of Portland, 

 in a deep railway cutting, the tertiary beds are well seen, and 

 consist, in ascending order, of boulder clay, fossiliferous stratified 

 clay and sand, and stratified sand and gravel. These beds appear 

 to be very irregular, being entangled in ledges of metamorphic 

 rock, which sometimes rise through them. The distinction between 

 the deeper water and shallow water parts of the deposits is in
