GLESSULA, SUMATRA AND JAVA. 103 



the mountainous region of India, and especially stands about 

 midway between oreas and jerdoni, both from the Nilgiris. 

 A similar species from Java is Hasselt 's Acicula cornea, fig- 

 ured on his unpublished plate 14, fig. 5, from the mountain 

 Salak." (Marts.) 



Prof. Boettger states that by the study of Mr. Rolle's speci- 

 mens of G. sumatrana, he sees that G. javanica is identical, 

 and the latter name should be withdrawn. Apparently 

 "javanica" is an error for cornea. The original account 

 follows. 



G. cornea Boettger. (PI. 14, fig. 3.) Shell not rimate, 

 subfusiform-turrite, rather solid, very glossy, bright chestnut- 

 brown, the apex not paler. Spire has very slightly convex 

 sides, apex exactly turrited, rather obtuse. Whorls 8, con- 

 vex, separated by a simple, impressed suture; minutely but 

 very distinctly, somewhat irregularly striate, the strias gath- 

 ered into groups at the suture and almost rib-like; last 

 whorl slightly tapering basally. Aperture subvertical, emar- 

 ginate-piriform subeffuse at the base, somewhat lipped with 

 violaceous inside, less than one-third the total length; mar- 

 gins joined by a curved callus, the right margin compressed, 

 nearly straight, columellar margin excavated, oblique, spir- 

 ally twisted, at the base oblique and distinctly truncate. 

 Length 13, diam. 5, aperture 5.5 x 3 mm. (Bttg.)

"This species has already been recorded under the manu- 

 script name Acicula cornea Hasselt, from the same locality. 

 It is the sole representative of the genus in Java, and stands 

 nearest to G. sumatrana v. Marts., as von Martens has al-
