Figure 4. Bulimus virgatus, Nobis. 



Habitat, unknown. 



i?ema/-Ar5.— Shell polished, striped brown and white ; margin reflected ; apex 

 rather obtuse; whorls five, slightly convex; columella a little concave; inte- 

 rior white. 



Figure 5. Bulimus porraceus, Nobis. 



Habitat, unknown. 



Remarks. — This shell closely resembles the last, and may be only a variety. 

 It is covered with a greenish yellow-colored epidermis. The margin is much 

 expanded, and together with the interior is a beautiful glossy white ; a small, 

 dark-colored band commences at the umbilicus, crosses diagonally the columella 

 and disappears internally. It is much more umbilicated than the last, and is a 

 heavier shell.

 and is beautifully marked with crowded concentric plaits.
