wo must so often relj upon transatlantic naturalists, for a foun- 

 dation on which to build our labors. 



In the third volume of the American Journal of Science. 

 Professor Silliman has described a locality of ichthyolites at 

 Westfield, the western parish of Rfiddletown, Conn., and also 

 s tates thai a specimen from this place, which he sent to Brong- 

 niart. was recognized by the latter as a species of the Palao- 

 thrissum of Blainville. In die sixth volume of the American 

 Journal] and also in the " Report upon the (leology of Massa- 

 chusetts," Professor Hitchcock has described the locality of 

 Sunderland, and has driven figures of two or three species found 

 at this place, which he says probably belong to the penus Par 

 laothrissum. In neither of these notices are we furnished with 

 any distinctive description of the fishes ; hut the figures of Pro- 

 f! ssor Hitchcock serve to show that their originals are referable 



lo two genera widely distinct. 



Dr. I»'l.:_.. some yi ace, read a paper before this so- 



ciety, upon the fossil fishes of Westfield, in w hich lie pointed out 

 the close affinity hetween tlie former and the existing Esox OSSCI/s^ 

 or the L< [iix:st< us of French authors. 'This paper has never 

 been published. 



Pr< assiz, well known for his valuable labours in this 



departmenl of natural science, has, in his greal work now in 



n e of publication, described buf two species of fossil fishes 

 from the United States, and these d< criptions are founded, m 

 pot, upon the drawings <>( Profe or Hitchcock, to which we 



have alluded, an 1 in pail upon single specimens of each which 



had found their wa\ to Europe. 'The first of these is seen in 

 . !<;, plate 11, of Hitchcock's Report, and Is referred bj 



\ iz tO his genUS PaleCOnisCUS, under the name ol I', /'////lis, 



imprehending in this 'j< mis, both the Palaoniscum and ror 



laothri "m of Blainville. The other species described is seen 



in fi . U> and LS of the same plate, and ignated as Eury. 



To this species I shall have occasion again to
