inadequate for exhausting the palseontological possibilities of so large a 

 district as the one under consideration. Added to this, the wi'iter has 

 not had sufficient time at his disposal to thoroughly work out the 

 material in his possession. Such of the species, as may ultimately 

 prove new to science, will bo treated in a subsequent paper, in which 

 they will be figured and duly described. The following is a list of the 

 f jrms collected during the past summer, and, although it is a very im- 

 perfect one, it is to be hoped it mny be of service as a basis for future 

 work in this part of the Chazy formation :

In connection with the above, it is but just that mention should 

 be made of the kind and generous manner in which Mi-. J. F. 

 Whiteaves, of the Geological Survey, rendered his valuable assistance 

 in the determination of critical species, for which, however, it must be 

 distinctly understood, he is in no way responsible.
