Heilprin'' s original desa^iption. — "Shell fusiform, of about 

 seven sub-angular volutions : whorls ornamented b}^ somewhat 

 obscure longitudinal folds, about twelve on the body whorl, 

 which are cut by several prominent revolving ridges commencing 

 at the shoulder angulation ; shoulder of the whorls more or less 

 smooth, with an obscure median revolving line, and a prominent 

 subsutural one ; aperture about the length of the spire, or 

 slightly exceeding it, the canal gently curved, moderately con- 

 tracfted, and somewhat expanding at the extremity ; outer lip 

 thin, and showing internally the external ornamentation ; base 

 with numerous revolving lines, which alternate in coarseness. 



"Length, i^/f inches. Knight's branch, Clark Co., Alabama." 



Our figure represents the typical Woods bluff form. Speci- 

 mens from Bell's landing and occasionally at Woods bluff show 

 a less marked carination and the space between the upper carina] 

 line and the suture is traversed by two or more spiral lines, 

 there are more spirals on the back of the anterior canal, the 

 columella is also nearlj^ rectilinear. This species doubtless 

 merges into F. mortoni Lea. 



Localities. — Alabama : Woods bluff, Gregg's landing, Bell's 

 landing. Lower Peach Tree, Butler, Hatchetigbee bluff, 

 Chocftaw corner. — Aldrich. Knight's branch. Cave branch. — 

 Heilprin. 



Type. — Probably in Acad. Nat. Sci. Phila. 



Specimen figured. — Woods bluff; Paleont. Museum, Cornell 

 University. 



Fusus ottonis, PI. 5, fig. 5. 



Syn. Fusus ineyeri (See Bull. Am. Pal., vol. i, p. 201, pi. 18, fig. 12, 

 1896). 

 Fusus ottonis Aid., Bull. Am. Pal., vol. 2, 1897. 



The type specimen of this species is herewith refigured. As 

 observed in vol. i, p. 201, this is considerably different from the 

 Midway form.
