bridge Museum, as well as by all modern palaeontologists. One 

 tbing tbcrcforc is certiiin, that wlicthcr or not our specimen be 

 identical witb that of Professor Hall, it has evidently no claims 

 to be considered a Lituites. In the present note, however, we 

 are unable to do more than announce the occurrence of the 

 genus Cryptoceras in our Canadian rocks, the characters of the 

 solitary specimen before us being too imperfect to warrant the 

 bestowal of a specific name. 



Since the above was written, we have learned that several 

 examples of this fossil type, under the name of Lituites undutus, 

 have been obtained by the Geological Survey of Canada from the 

 Black River limestone of Lorette. It is very probable that many 

 of the Silurian Lituites will prove, when more closely examined, 

 to belong to Crijptoceras, or to Barrande's new genus Nothoceras, 

 a notice of which (Bulletin de la Societe Geol. dc Fi'ance, t. xiii. 

 p. 380) has only just reached us. Although stated to have been 

 read before the Society on the 3rd of March 1856, the Bulletin 

 containing the notice was not issued until March in the present 

 year. In Nothoceras, the bent edges of the septa (the goulot of 

 the French palaeontologists) protecting the siphuucle, instead of 

 being deflected backwards as in Nautilus, Cyrtoceras, &c., are 

 deflected forwards or towards the opening of the shell, as in the 

 Ammonites.
