The great peculiarity of list No. 3 is the very large proportion of 

 land-shells which it contains ; but these, it must be remembered, are 

 all derived from one or two small localities. They are only sparingly 

 found in other parts of the formation, and it may be observed that 

 every one of the Helices and Cyclostomata found in table No. IV., 

 which comprises the general contents of the whole formation, is also 

 to be found in list No. III., which latter professes to give only the 

 contents of one or two small localities near the edge of the forma- 

 tion, and where we might fairly expect the remains of the terrestrial 

 fauna of the district to have accumulated on the shores and margins of 

 the waters. The two lists must, therefore, be looked upon as con- 

 temporaneous ; the one showing the terrestrial fauna washed into 

 and found on the margin of the lake, the other the real inhabitants 

 of the brackish water.
