Bulimulus pachys n. sp. 



Shell umbilicate, ovate-conic, solid and strong ; surface smoothish, 

 with slight growth-wrinkles, rather regular and close on the spire 

 and disposed to be interrupted. Spire acutely and straightly conic 

 with subhorizontal sutures, the apex small, obtuse, earlier If whorls 

 regularly and rather finely costulate vertically. Whorls 7s, con- 

 vex ; sutures well impressed, the last hardly descending ; last 

 whorl regularly convex and inflated. 



Aperture subvertical, ovate, somewhat over half the length of 

 shell, white inside ; peristome unexpanded, rather blunt, the outer 

 margin regularly arched, columella slightly concave, its margin 

 broadly reflexed, with a salient angle at junction of reflexion with 

 basal lip ; parietal callus moderate ; umbilicus deep and rounded. 



Alt. 32J diam. 20; alt. of aperture 18 mill. 



Province of Bahia, Brazil (v. d. Busch). 



The type is a faded, decolored specimen, showing traces of a 

 median white girdle, brown above and slightly so below it, as in B. 

 durus Spix. It is considerably like B. heterotrichus in size and form, 

 but is unlike that species in the less oblique aperture with blunt, un- 

 expanded outer lip, the differently formed columella and the costu- 

 late apical whorls. In general aspect it somewhat resembles Bin- 

 ney's B. patriarcha. The columellar lip is pressed in above, unlike 

 that of B. durus, which is, besides, a smaller species. 



Bulimulus chrysaloides n. sp. 



Shell perforate, oblong turreted, thin, deep reddish-chestnut, 

 somewhat paler on the spire ; surface lusterless, with irregular, indis- 

 tinct growth wrinkles and microscopic crowded spiral strige, very 

 superficial and probably cuticular. Spire long, the apex obtuse, 

 If nepionic whorls regularly- vertically costellate, the riblets straight, 

 closer on the latter portion. Whorls 6s, moderately convex, the 

 last a trifle descending in front ; sutures impressed. 



Aperture small and short, slightly oblique, short-oval, contained 

 slightly less than 2 s times in length of shell, brownish-vinous with- 

 in ; peristome thin, slightly expanded ; columellar margin expanded, 

 not reflexed, forming a long triangular plate concave on the apertural 

 side ; the inner edge of columella rather acute, slightly concave. 



Alt. 22, diam. 10 mill; alt. of aperture 8z mill. 



Alt. 18s, diam. 91 mill; alt. of aperture 8* mill.
