 (1885). KOBELT, C. Cab., p. 81.

 Glandina; this one especially on account of its glossy, trans-

Shell narrowly perforate (the perforation half covered), 

 elongate, solid, opaque, glossy ; pale rufous with red-chestnut 

 flammules; finely striate, more sharply so below the suture. 

 Spire elongated, obtuse at the summit. Whorls 8, a little
