 of the original specimen. Figured from a topotype received 

 from Arango.

Very closely related to Cyl. eleyans, but strongly striate,

 brownish below it. Internal column with four lamellae in 

 the median whorls, the upper lamina dilated ; in the last whorl 

 it has two lamellae (Arango}.

Shell slender, turreted, nearly regularly tapering, or with 

 the upper third more rapidly decreasing, thin, corneous, 

 somewhat transparent; somewhat glossy, obliquely and very 

 closely striate. Whorls 18-20, rather convex, the last pro- 

 duced forward and somewhat descending, with no trace of a 

 basal keel, the neck sharply but still closely and finely striate. 

 The spire is entire or merely the tip may be broken, the nepi- 

 onic shell consisting of about 2y 2 rather globose whorls. 

 Aperture oblique, subcircular, the peristome white, somewhat 

 thickened and reflexed. Axis slender, with three delicate 

 lamellae the upper largest in the intermediate whorls, the 

 lower smallest, armed with rather long, obliquely placed
