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

 mill. long. 12 wide. Sr. Pax 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 was probably 

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

 It is probably a species of the interior region. 



O. AI KISCERVINA (Ferussac). PI. 9, fi<jf. 3. 



Shell similar to the large form of O. <nif/nlatns but having the lips 

 sinuous, forming a distinct "spout," much as in O. fnsiformis. 

 Distantly striped.

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

 figure of that, species. The name is earlier than anynlalus ; 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 mv plate. 



0. AN<;II.ATIS (Wairner). PI. 9, fig. 8 (typical) 4-7 (var.). 



Shell oblo.ng-conic, solid, with delicate longitudinal striiw, at the 

 sutures suhrugose. 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,
