BY HENRY VENDRYES. 



Cylindrelht (A now a) inusitata, Vendryes. PI. I, tigs. 1 and 2. 



Shell much elongated, cylindrical, rimate, somewhat shining and 

 transparent, color light brown ; spire slightly tapering both above 

 and below its greatest diameter, which is about the middle ; 

 truncate with the loss of 7 to 8 whorls, whorls remaining 11 to 12, 

 planulate, shouldered by an early obsolete angle, the last detached 

 and descending, strongly carinated at the base, the carina extending 

 to the back of the aperture ; striae waved, strong and compact, cross- 

 ing the whorls obliquely and continued up to and many crossing over 

 the edge of the suture, which appears fringed here and there by their 

 intrusion ; aperture like that of Dunkeriana, but rather larger in 

 proportion to the shell, and less oblique than in that species, well 

 produced over the penult, whorl. Height 18 mm., greatest breadth 

 above the middle of the spire, 3 mm.; aperture, 3 mm. high, 2^ 

 mm. wide. 



This species is remarkable for its produced and detached aper- 

 ture, placing it in the same group to which princeps belongs. 

 Specimens were received from Mr. Bancroft, who collected them on 

 the mountains at Upper Leighton, near Spring Garden estate in the 

 parish of Saint George.
