Blandia Bairdiana, Chitty. 



Hab. Yallah's Hill. 



Form, subdiscoidal. Colour, rery pale horn or pure white. 

 Sculpture, about 30 or 40 spirai carinse, almost obsolete, scarcely 

 visible under a l:ą:-inch microscope, about 5 being rather niore sharp 

 than the ręst ; on the upper whorls about 7 . Spire, very slightly 

 elevated, with rather concave outlines. IVhorls, 3į, moderately 

 rounded, with a light suture : lašt whorl rather flattened at the peri- 

 phery. Aperture, semielliptical, very much produced from the 

 body-whorl, rather depressed above, but elegantly expanded through- 

 out. Labrum, very much produced above, joining the body-whorl 

 in a very graceful serpentine curving lamella, (by which the shell 

 may be distinguished,) much thickened and reflected. Labium, mo- 

 derately detached from the body-whorl and thickened and reflected, 

 slightly curved to the right below, very much below the plane of 

 the labrum. TJinbiUens, broad and moderately deep. Labral la- 

 mella, very sharp and narrowly produced. Opercuhim, deep con- 

 cave, apparently smooth, or with blunt vertical lamellae, margined all 

 round, labial side much curved, rather pointed at upper and lower
