Brunswick. They were found in beds of Leda clay 

 passing upwards into sand and gravel. At the Ja'cquet 

 river, in the same district, the bones of a small cetacean 

 have been found, and have been described by Dr. Gilpin 

 and Dr. Honey man.* They were referred by Dr. Gilpin 

 to Beluga Vermontana of Thompson from the Pleistocene 

 of Vermont. Similar bones have been found in the Leda 

 clay of the St. Lawrence valley, and have been compared 

 by the late Mr. Billings with the skeleton of the recent 

 B. catodon, L., of the St. Lawrence, with which the 

 so-called B. Vermontana is probably identical, as the 

 specimens above referred to, and examined by Billings, 

 certainly were. 



Mr. Matthew has found Tellina Graenlandica at Horton 

 Bluff, in beds probably of the age of the Saxicava sand. 

 Mr. Matthew has also published f a valuable synopsis of 

 the fossils found up to 1876 in the Post-pliocene of New 

 Brunswick, in which the number of species of mollusca is 

 raised to more than thirty. He notes the important fact 

 that the shells found on the coast of the baie de Chaleurs 

 are of more northern type than those in the bay of Fundy, 

 which conform more nearly to the assemblage found in 

 these deposits on the New England coasts, so that the 

 existing geographical regions were already to some extent 

 established on the coast of North America in the period 

 of the Upper Leda clay. 



It is probably to the more modern part of the Pleisto- 

 cene, if not to a more recent period following the elevation 

 of the land, that the bones of the mastodon found in cape 

 Breton, and described in "Acadian Geology," belong. To
