A large, remarkably slender species, of coarse exterior, allied 

 to S. infundibuliformis, and much resembling Limnea umbrosa 

 in form.

Bulimus elobatus. Testa solidula, elongato-ovata, longitu- 

 dinaliter plicoso-striata et lineolis volventibus interrupts corrosa, 

 epidermide sordide luteo et viridi marmorata induta, arete urn- 

 bilicata : sph'a anfr. 5 convexis, ultimo magno : apertura angus-

Belongs to the same group as B. fulguratus and B. malleatus, 

 characterized by the large fold on the columella. It is the 

 largest of the three, resembling the former in its sculplure and

 distinguished by its unreflected lip, its narrow aperture, less con- 

 spicuous and more oblique columellar fold, more ventricose and 

 less oblique whorls. 



Bulimus morosus. Testa crassa, rudis, ovata, albido-cinerea,

 postice angulato ; plica columellari ampla.Long. 1^, lat. 1 poll.

Of the same group as the preceding, but is smaller, more solid 

 and less elegant than its associates. Its want of epidermis and

Bulimus prolatus. Testa ovoidea, antrorsum ano-ustata, 

 leviter striata, albido-cinerea, fasciis quatuor liturarum ferrugine- 

 arum cincta : spira ovato-conica ; anfr. 5 convexiusculis: apertu- 

 ra elliptica, totius longitudinis dimidium adequans ; labro sim-
