Remarks. — This is a very ornate little species, being covered with close perpendicu- 

 lar ribs and four dark brown revolving bands, which give the shell a dark appearance, 

 although the ground is yellow. The two middle bands are approximate, and the low- 

 est band is the strongest. Immediately below the suture there is usually a light line. 

 It belongs to the group of which Melania (Goniohasis) Deshaysiana (nobis), may be 

 considered the type, but is nearest allied to inclinans herein described. It is nearly 

 of the same size and outline, but the regular perpendicular folds and the distinct bands 

 distinguish it at once. The apicial whorls are disposed to be carinate. The aperture 

 is one-third the length of the shell. The specimens were all incrusted with black 

 oxide of iron, which, being removed, the epidermis was found to be smooth and polished. 

 One or two revolving stri»3 immediately under the suture decussate the folds.
