Melania Portellii. Mel. testa acummato-subulatd, vi- 

 rescente-olivaced, ad suturas late pallidis, anfractibus 

 septem ad octo, longitudinaliter subplicatis, spiraliter

 olivaced, anfractibus undecim ad duodecim, p/ano-con-

Anthony, Pro. Nat. Hist. Soc. Boston, 1851. 



Hab. Southern United States. 



Characterized by an unusual number of whorls, encircled
