Xemar/cs.-Two specimens were sent by Mr. Hallenbeck for my examination Both 

 have xmperfect plicaa on the spire which is very obtuse, and both are evidently adults 

 The upper whorls are carinate, but the inferior whorl closes on the angle so as to 

 obliterate the carination. On the body whorl this angulation is nearly obsolete It 

 has nearly the outline of Melania (Goniobasis) abrupta (nobis), but that species is 

 not plicate and is a thicker shell. The aperture is one-half the length of the shell 

 I dedicate this species to my friend Joseph Leidy, M. D., who has done so much for 

 American Zoology and comparative Anatomy.

 to Melama (Gcnuobas iS ) Deshaysiana (nobis), but is a smaller species. Its chestnut 



brown color reminds one of Melania (Goniobasis) castanea (nobis), but it is not so 



elongate and is thicker. The aperture is more than one-third the length of the shell.
