APPENDIX TO THE PULMONATA, 



The fresh water pulmonates of Alabama seem not to 

 have been thoroughly studied, and there are available no 

 records that locate a considerable number of species which 

 might very reasonably be expected to occur in the State. 

 A large share of these have been omitted from the list 

 only such species being included as have a local record 

 within the limits of the State or within contiguous portions 

 of adjoining States. The land shells, having been more 

 thoroughly studied, afford sufficient records to make it 

 probable that only a few species likely to occur within the 

 limits of the State have been omitted. It is quite proba- 

 ble that a careful exploration of the mountains in the north- 

 ern part of the State may bring to light some of the few 

 species that have recently been described as occurring in 

 the not distant mountains of Tennessee and North Caro- 

 lina. One of these Mesodon Chilhoweensis, Lewis, occurs 

 in northern Georgia, as is established by an immature 

 specimen in the National Museum ; and the occurrence of 

 this species in East Tennessee and Georgia would seem to 

 warrant the expectation that it might also be found in Al- 

 abama.
