Anthony, MS. in Mus. Cuming. 

 Melatoma rectum, Anthony. 

 Melatoma salebrosum, Anthony. 



Hab. Alabama. 



The shells represented at Fig. 7a, lb, and 8, are the 

 specimens transmitted to Mr. Cuming by Mr. Anthony 

 with the names M. rectum, quadratum, and salebrosum. I 

 believe them to be varieties of one and the same species, 

 and have selected the name quadratum as being most cha- 

 racteristic of their peculiarity of form.
