below ; columella oblique, uneven, the columellar lip very broadly 

 dilated above, sinuous ; base effuse, narrow and spout-like. 



Length 40, diam. 10; length of aperture 15.6 mill. 



Brazil: Province of Minas Geraes (Rang.), Bahia (v. Ihering).

Much more slender than its allies. Rang's type measured 40^ 

 mill. long. 12 wide. Sr. Paz obtained this species, with many other 

 shells from northern and interior Brazil, at Rio Janeiro; but accept- 

 able evidence of its occurrence there is wanting. He w 7 as probably 

 misled as to tire locality by whoever supplied him with the shells. 

 It is probably a species of the interior region. 



O. AUKISCERVINA (Ferussac). PI. 9, fig. 3. 



Shell similar to the large form of 0. angulatus but having the lips 

 sinuous, forming a distinct "spout," much as in 0. fusiformis. 

 Distantly striped. 



Brazil: (Mawe); probably Prov. Minas Geraes.

This is probably a form of 0. angulatus, and resembles Reeve's 

 figure of that species. The name is earlier than angulatus ; but in 

 the final arrangement both names will doubtless stand, either as 

 species or sub-species. It is known to me solely by the original 

 figure, copied on my plate. 



0. ANGULATUS (Wagner). PI. 9, fig. 8 (typical) 4-7 (var.). 



Shell oblong-conic, solid, with delicate longitudinal strise, at the 

 sutures subrugose. Whorls 9, slightly convex, the last shorter than 

 the spire. Spire conic, the apex a little obtuse. Aperture triangu- 

 lar, dilated above, compressed below, narrowed ; margin expanded,
