Notes on the Fossils of the Bahamas: Mr. W. 

 H. Dall. 



The rocks of the Bahamas, apparently all 

 Pleistocene, are of two kinds, marine sedi- 

 mentary and aeolian calcareous sands. The 

 former contain the common marine West In- 

 dian shells now living about the Bahamas, 

 with no extinct species. The aeolian rocks 

 proved to contain quite a fauna of land shells, 

 especially characterized (like the recent land 

 fauna) by the prof usion of Cepolis and Cerion. 

 In this respect it recalls the Oligocene land 

 shell fauna of the Tampa silex beds, of which 

 the Bahama Pleistocene shells are an analogue 

 but not a derivative. The latter unexpectedly 

 proved to contain a number of extinct species, 

 doubtless the ancestors of the present fauna. 

 Curiously enough, these ancestral forms are 

 more like existing species of Haiti and Cuba 

 than they are to their actual descendants, 

 which may be accounted for on the hypothesis 

 that a great increase in variability accom- 

 panied their invasion of the newly elevated
