 Cylindra elongata Hirase n. sp. pi. xl, figs. 234, 235. 



Shell very long and narrow, cylindrical, with impressed, 

 closely punctured revolving lines; spire small, decussated; 

 body-whorl rather smooth and glossy with faint growth lines, 

 and very long containing about eight times the length of the 

 spire or four times the diameter of the shell ; aperture linear, 

 outer lip thin, columella strait with eight oblique anterior plic;*. 



Length 26.2 mm., diam. 7 mm., length of aperture 22 mm. 



Loc, Kikai-ga-shima, Osumi ; fossil in a Pliocene(?) deposit. 



This white fossil shell somewhat resembles C. arctata 

 Sowb., which Tryon identified as a synonym of C. crenulata, 

 but it is longer and narrower. It seems to me that it has no 

 relation to the other species of Cylindi a.
