elegantly waved folds, which are bluntly tuberculate at the periphery of upper whorls and at 

 the shoulder of last whorl, where they are sharper, 14 in number on last whorl, they disappear 

 at some distance from the aperture. The spiral sculpture consists of elevated striae in the 

 concave part of whorls and at the base of shell, the rest of surface being impressedly striated. 

 Under the lens, fine growth-striae are visible and give a dull appearance to the surface. Colour 

 whitish with brown spots, which are irregular on upper whorls, form large brown bands on 

 beginning of last whorl, the back of which is nearly uniformly brown-grey. Aperture oblong- 

 ovate, with the usual channel above, passing in the sutural channel; peristome rather blunt, 

 smooth, with a sinus below, 16-Hrate internally, basal lira stronger and toothlike, the other 

 ones are long; columellar margin nearly straight, rounded, enamelled, with numerous wrinkles 

 in the lower part and a few pustules. Canal rather wide, dorsally bordered by a brown line. 



Operculum yellowish-horncoloured, with probably apical (broken) nucleus. 



Alt. 18, lat. 9; apert. alt. S^a, lat. 3Y3 Mill. 



The nearest ally of this species seems to be C. orientalis Adams, but the new species 

 is much more elongate, being twice as long as broad, though the nucleus is wanting, the breadth 

 of C. orientalis on the contrary is much more though the nucleus is present; in the back view 

 the row of nodules of last whorl, runs about half way the total length of shell, the spire in 

 the new species being longer than in C. orientalis, where that row runs considerably higher on. 

 Moreover the colour and sculpture seem to be different, as far as may be judged from the figure.
