THE GEOLOGIST. 



opinion that the lip, or perfect termination, assumes a 

 different shape in almost every species, and that it has a 

 simpler form in the adult, or full grown shell, than in im- 

 mature individuals. He considers that the lateral pro- 

 longations, were successively absorbed and reproduced, 

 but were never added to the final lip, and that they were 

 for the support of the animal, which extended beyond the 

 last chamber, contrary to the presumed conditions of the 

 mature individual.

 environs ; and then states, that the strata between Lakes
