Bulimus edwardsianus GASSIES, Faune Conch. Nouv.-Caled., i, 

 p. 40, pi. 4, f. 2, 1863. 



Var. pinicola Gassies. (PI. 17, fig. 2(5.) Distinguished from 

 typical fibratns by the smooth epidermis, without wrinkle striae, and 

 having some, white dots below, and the very deep blood red color of 

 the interior. Type measures: length 90, diam. 44, aperture 45 

 mill. Seems a very weakly characterized form. Perhaps the shell 

 figured on plate 15, fig. 17 belongs to this race. Isle of Pines* 



Crosse has figured a sinistral monster, apparently belonging to this 

 variety. See pi. 17, fig. 27. 



Var. bovimLS Brug. (PI. 20, fig. 41). Elongate, pale olivaceous 

 with brownish streaks ; lip whitish with a pale orange submargin, 

 the throat light ochreous ; columellar fold small, the parietal tubercle 

 scarcely noticeable. This variety includes var. pallidula Crosse. 



Var. BAIRDI Reeve. (PL 19, figs. 35, 38). Much elongated? 

 turreted, solid, the cuticle varying from yellow with brown streaks 

 to chocolate-brown. Aperture small, yellow or orange-red within, 

 the peristome heavily calloused, white ; parietal tubercle high and 

 conic; columellar fold strong; lip usually with a thickening and 

 shallow sinus above. Length 76, diam. 33 mill. 



PI. 15, fig. 18 and pi. 16, fig. 25 are also forms referable to or 

 near bairdi, though not typical. 



Var. peculiars Kobelt. (PI. 17, figs. 28, 29). Much elongated 

 fusiform, solid and thick, irregularly transversely wrinkled, the wrink- 

 les oblique, confluent. Whorls 8i, the last ascending to the aperture, 

 which is small, much contracted and buff-white ; peristome ex- 

 tremely thick, the outer lip deeply sinuated above, then thickened; 

 columella with a very thick fold-like tubercle, the heavy parietal 

 callus bearing a strong, acute tubercle. Alt. 78, diam. 32, length of 

 aperture 38 mill. Isle of Pines, 



Described from one dead shell, incrusted with calcareous ma- 

 terial. 

 Var. LEUCOLENUS (Crosse). PI. 45, fig. 6. 



Shell very narrowly and covered perforate, oblong-conic, rugose- 

 striated ; whitish under a chestnut epidermis, which is longitudinally 

 radiated with darker; suture impressed. Whorls 7, a little convex, 

 the earlier 3 wholly destitute of cuticle, whitish, the last whorl a 

 little shorter than the spire (in the ratio of 32 : 38). Aperture ob- 

 long-oval, milk-white within ; peristome thickened, sub-reflexed,
