 more than a dozen other species of cerithium. Fusus intor-

 idea of the others.* 



3. Moutecchio-Maggiore. The trappean formation is 

 here so predominant, and of such a crystalline structure in 

 some of its parts, that it is more difficult to recognise here, 

 at first sight, the same origin and association of rocks than 

 in the preceding places : yet, if the limestone is not found in 

 alternating strata, it occurs in inclined superincumbent beds, 

 and we recognise the epoch of this formation in the fossil 

 shells which are disseminated, not in the amygdalo'idal 

 nodules, for they contain none, but in the brecciola that 

 unites them. These shells are of neighbouring species, and 

 sometimes absolutely the same species as that of the two 

 places above noticed, and consequently of a contemporaneous 



* The author, in his separately published memoir gives a long list of 

 the fossil shells found in the calcareo-trappean rocks of the Vicentin. 

 The list is too long for insertion here, I have therefore extracted from it 

 the following catalogue of the generq with the number of their species.
