rounded, showing no decided lines of stratification, but irregularly as- 

 sociated with isolated beds of gravel and sand, among which great 

 quantities of marine shells of comparatively^ recent origin occur. One 

 of these localities is on the Prescott Road, about a mile and 

 a half from Kemptville, where a vast accumulation of Tellina 

 gi^cenlandica overlays a two feet bed of limestone gravel, the latter 

 resting on gravel of a still coarser qualit}', and of more angular 

 fragments, and irregularl}^ mixed up with sand and clay, some 

 of the bo^vlders being from 6 to 10 inches in diameter. The height of 

 this locality is about 350 feet over Lake St. Peter. At another locality, 

 near Armstrong's Mills, the shells consist QhiQ.^y oi Saxicava rugosa 

 mixed with sand and loam, at a height of about 300 feet above Lake 

 St. Peter. In Kenj^on, on the Garry river, these shells occur at the 

 height of 270 feet above Lake St. Peter. On the road between the 5th 

 and 6th concessions of the township, on the 19th and the 21st lots, 

 these shells occur at the height of 330 or 340 feet above Lake St. 

 Peter. Two localities occur in Lochiel, one of them on the 15th lot of 

 the 1st concession, at the height of 264 feet, and the other on the 5th 

 lot of the same concession, 280 or 290 feet above Lake St. Peter, where 

 the marine shells are mixed with the sand, and where bowlders and 

 fragments of limestone and sandstone abound. 



Prof Edward Hitchcock* described the brown coal deposit in Bran- 

 don, Vermont, and referred it to the Pliocene or Newer Tertiary. He 

 found it abounding in fruits and lignites, which appear to have been 

 transported by water, and probably accumulated in an ancient estuary. 

 It abounds in white and variegated clays, water-worn beds of sand and 

 gravel, beds of carbonaceous matter not bituminous, and deposits of 

 iron and manganese. 



T. A. Conradf described, from the Miocene of Upper California, 

 Gnathodon lecontei^ now Bangia lecontei, and Ostrea vespertitia. 



In 1854, Dr. LeidyJ described, from the Post-pliocene, of Ashley 

 river, South Carolina, Arctodus py'istinus, from Kansas, Camelops 

 kansanus ; and from the mouth of Pigeon creek, below Evansville, Ind., 

 Canis primoevus, now C.'indianensis. From the Pliocene, on Bijou 

 Hill, east of the Missouri river, Hippodon specwsics, now Hippothe- 

 riiim speciosum^ and Merycodus necatus, now Cosoryx necatus; from 

 the Miocene of Nebraska, Deinictis felina.
