NEW MELANID^E OF THE UNITED STATES. 299 



dining to yellow. It is very closely allied to Melania {Goniobasis) duhiosa (nobis), 

 but differs in the aperture being slightly more constricted and in being rather longer, 

 having one more whorl. It is also near to castanea (nobis), but is larger and not 

 chestnut brown. The aperture is about one-third the length of the shell. I dedicate 

 this species to the late President Estabrook of Knoxville, Tennessee.

Remarks. — Among some twenty specimens before me, there is no difference in form 

 or markings, except that some have the bands slightly broader than others. The 

 two middle bands are rather closer together, and the under one of these two is gene- 

 rally the smaller. It was sent to me by Dr. Showalter under the name of M. grata, 

 Anth., but while it has the four bands like that species, it is more slender, is not 

 yellow, has a less aperture and one more whorl, and is more fusiform. The aperture* 

 is rather more than one-third the length of the shell.
