it may have been applied to this species owing to the basket-like appearance of the

Nors.—Bulimus californicus, Reeve, Conch. Icon. v., Bulimus, t. 56. fig. 378, which 
has not been found in California by later collectors (gf. Binney & Bland, Terr. air- 
breath. Moll. N. Am. v. p. 21; Manual Am. Land-Shells, p. 22), is perhaps a non-adult 
specimen of a slender form of 0. serperasirum. 
Otostomus hygrohyleus (Orb.), from Bolivia, is very similar to this species; but may 
be distinguished from it by the more broadly dilated, projecting part of the peristome, 
the more irregular, coarse, wrinkle-like striae, and the bands being interrupted into 
arrow-like spots.
