GIBBONS : NEW EAST AFRICAN LAND SHELLS. I4I 



margin thin and plain; color jet black, with a line of irregular 

 dusky white spots along keel; tentacles 4, upper pair short, thick 

 and cylindrical, of a dark neutral color, lower pair shorter and 

 thicker, distinctly bifid at extremity, light greyish; foot one-third 

 breadth of body, moderately high; upper surface of body minutely 

 granulate, glossy. 



■Length about 2 in. 



Young are not keeled and are of a light umber color, thickly 

 speckled and mottled with rich brown. 



Occurs on the ground under stones, &c., at Mozambique. I

 merely a variety, the only important differences being the size and 

 color.
