770 PROCEEDINGS OF THE ACADEMY OF [DcC, 



Western Nicaragua : Pol von. in the department of Chinandega. 

 Types are No. 5,096, A. N. S. P., collected by the McNeil expedition. 



Compared with the Holarctic Sphyradiu7n cdentulurn, this tropical 

 species is less cylindric, tapers more, and the whorls are much less 

 convex; moreover, the color is different. 



It was figured in these Proceedings under the name Pupa polvonensis 

 many years ago. A description is now supplied. It is the first Neo- 

 tropical species of the genus, but until jaw and teeth are examined 

 the generic position ^^■ill remain uncertain, although the shell has the 

 form of Sphijradium.
