Hub. — Tennessee, Prof.- Troost ; near Vienna, Dooly County, Georgia, in a small 

 stream tributary to Flint River, Rev. George White. 



My cabinet and cabinets of Mr. White and Dr. Hartman. 

 Diam. "32, Length -91 inch. 



Remarks. — I have a number of specimens from Mr. White, and one a long time 

 since from Prof Troost. It belongs to the group of which Melania ( Goniobasis) costu- 

 lata (nobis) may be considered the type, but it is more cylindrical and has more 

 distant folds. It is also allied to Melania (Goniobasis) decora (nobis), but is more 

 cylindrical, has more distant folds, and has no cancellate stria3. The folds are curved 

 and incline slightly to the left. The aperture is not quite one-third the length of 

 the shell. Some specimens are disposed to be slightly brownish inside. 



Goniobasis Viennaensis. PI. 37, fig. 160. 



Testa, plicata, subfusiformi, olivacea, subtenui, evittata; spira regulariter conica ; suturis irregulariter 

 irnpressis; anfractibus septenis, planulatis ; apertura subgrandi, rbomboidea, intus cieruleo-alba • 

 labro acuto, sinuoso ; columella iucurva, inferne incrassata, parum contorta. 



Shell folded, subfusiform, olivaceous, rather thin, without bands ; spire regularly 

 conical ; sutures irregularly impressed ; whorls seven, flattened ; aperture rather large, 

 rhomboidal, bluish white within ; outer lip acute, sinuous ; columella bent in, thick- 

 ened and somewhat twisted below.

Eemarlcs. — A number of this species came with Doolyensis, herein described, but it 

 is quite a different species. It is regularly conical, while the other is subcylindrical, 

 and the ribs are more numerous and closer, and are not quite so much curved. The 

 aperture is also larger. It is allied to Melania ( Goniobasis) Deshaysiana (nobis), but 

 while it is nearly of the same outline it differs in being wider, also in color, and it has
