Bulla oblonga. A. Adams, Sow., Thes. Bulla,^ sp. 50, pi 123. A 

 large shell, reddish brown with pink spots and zoned indistinctly with 3 or 

 4 broad blue-black bands ; has been mistaken for Quoy's B. australis ; it is 

 said to occur in the Philippines (H. Cuming), probably only a variety of 

 B. ampidla. In S.A. (Guichen Bay, Lake Eliza, raised beaches, etc.), it is a 

 common pleistocene fossil where it attains a large size. Long. 55, lat. 31.
