Bohemia, and with certain portions of the Upper Silurian in the Scan- 

 dinavian beds. 



Seco7idly — That, though synchronous with these several deposits, the 

 Anticosti beds contain few, if any, fossils identical with those in their 

 European or American equivalents ; in other words, that the sea, at 

 the time of the deposition of these synchronous but distant beds, held 

 a different fauna at Anticosti from that existing in the European seas, 

 or in the neighboring basin of New York. 



Thirdly — That the fauna of Anticosti shows a more intimate rela- 

 tion to the synchronous fauna of northern Europe than to that of the 

 New York basin. 



This last conclusion, though well supported by the testimony derived 

 from the comparison of fossils, is presented with much doubt. 



It is not possible to present here the data for these conclusions. 

 The other gentlemen engaged upon the expedition will soon have 

 completed their work upon the collections, when the geology of this 

 interesting island will be made the subject of a special report. In 

 giving the results of the examination of a single order I feel that I 

 may have committed many errors, but, as the assertions of the Cana- 

 dian Report have more than once been made the basis of argument 

 in this Society, I feel justified in presenting these possibly immature 

 conclusions. 



Mr. Marcou, in alluding to the few localities in which pri- 

 mordial fossils have been found in Europe (at only two j^laces 

 in Bohemia,) mentioned several in this country, as Braintree, 

 St. Mary's Bay (Newfoundland), Georgia, Highgate, and 

 Swanton, Yt., the vicinity of Quebec, and in Tennessee. In 

 Vermont had recently been discovered a species of Ampyx^ 

 the first ever found in America, which had been named A. 

 Halli. He exhibited several specimens of Conocephalites^ 

 Ampyx, Camerella, &c. 



He also read an extract from a letter to himself by Prof Op- 

 pel, announcing that he had found in the lithographic stone 

 at Solenhofen, Bavaria, in the Upper Jurassic, a fossil having 

 a long tail, as in Hamphorhynchus (De Meyer), feathers of 

 the wings and tail well preserved, about twenty elongated 

 vertebrae, a very small pelvis, as in Pterodactyl, and the leg 

 as in birds with a simple metatarsus, with three toes having 

 long nails ; the head is wanting ; the length is about 1^ feet. 

 Prof. Wagner, of Munich, has described it as a reptile, 

 though it seems rather to belong to the birds. If birds
