DESCEIPTION OF A NEW SPECIES OF CLATEURELLA, PROBABLY 

 FEOM CEYLON. 



By H. B. Pkeston, F.Z.S. 



Read 8th November, 1907. 



The shells which form the subject of the present paper were recently 

 found by me among a number of others from the collection of the late 

 Hugh Nevill, and are in all probability from Ceylon. I have been 

 unable to identify them with any known form, and as there are 

 several specimens all showing the same characters I now venture to 

 describe the species. 



ClATHUEELLA. BlETSI, n.Sp. 



Shell elongate, fusiform, white, painted with rows of reddish- 

 brown spots ; remaining whorls spirally sculptured with coarse ribs, 

 increasing from three on the upper whorls to six on the body-whorl, 

 which are intersected by transverse grooves, giving the shell a beaded 



appearance; suture impressed; aperture narrow; columella descending 

 obliquely ; peristome bent inwards and serrated by the termination of 

 the spiral ribs. 



Length 6, diam. maj. 2'25 mm. ; aperture, length r75, diam. "25 mm. 



j5a3.— Ceylon ?
