Uniiiswick. They wore found in beds of Leda clay 

 [liissing upwards into sand and gravel. At the daccpiet 

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

 have been found, and liavc been described by I)r. (iil})in 

 and Dr. Honeyman.* They were refcii'ed l)y Dr. Clilpin 

 to BvliKjti ViriiiinifdiKi of Thomi)soii from the Pleistocene 

 of X'ermont. Similar bones have been found in the Leda 

 clay of the St. Lawrence valley, and ha\e Iteen coni])ared 

 by the late Mr. IWllings with the skcleioii of the recent 

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

 so-called J>. T^'niiniifdiia is probably identical, as the 

 specimens above referred to, and exannned by JJillings, 

 I'ertainly were. 



Mr. Matthew has found TiUina (1 rnnhiiKyini at ][orton 

 lUul'l, in l)eds prol)ably of the age of the Sa.\icava sand. 

 ^Ir. j\Litthew has also ])ublished+ a valuable synopsis of 

 the fossils found up lo 1S7<) in tlie I'osi -pliocene of New 

 l'>runs\vicl<, in wliich the number of species of mollusca is 

 raised to more than thirty, lie notes the im])ortaiit fact 

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

 are of more norlhern type than lliose in the biiy of Fundy, 

 which conform more nearly to the asseml)lage f(jund in 

 those deposits on the \ew iMiglaml coasts, so that the 

 existing geogra])hical regions were alread'' to some extent 

 established 011 the coast of Xorih .Ameiica in the period 

 of the rpi)er Leda clay. 



It is probably to the more modern i)art of the Tleisto- 

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

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

 lU'cton, and descril)ed in "Acadian (ieolou-v," belong. To
