We have found nothing but fragments of this species in the 

 Lignitic, and the type figured by Aldrich is quite imperfe(ft. 

 When better material is obtained it can be figured to advantage.

Aldrich" s original description. — "Shell oblong-ovote, rather 

 flat, .surface smooth; labrum crenulate within, smooth on the base 

 and flattened, refled'led somewhat and raised above base of shell; 

 aperture slightly crenulate within, expanded below. 



''Locality. — Gregg's landing, Ala." 



Also found at Woods bluff, where it "is broader posteriorly 

 than typical smithi, and has a less conspicuous posterior termina- 

 tion of the labium, yet it is most likely of the same species. It 

 .seems to be the forerunner of C. dalli Aid." — Har. 



Type. — Aldrich's collecftion. 

 Aporrhais gracilis, " PI- 9. %• i- 



Syn. A. gracilis Aid., Geol. Surv. Ala., Bull, i, 1SS6, p. 32, pi. 5, fig. 14. 



Aldrich's original description. — "Shell fusiform, whorls eight, 

 spire high; embryonic whorls smooth, the others to the body 

 whorl with longitudinal ribs which curve to the left into the su- 

 ture and are crossed by fine revolving lines; body whorl expanded 

 into a broad outer lip, furnished with two digitations, the poster- 

 ior one the largest, rising in some specimens into a long, sharp 

 point, strongly grooved to the apex. The outer lip extends up 

 the spire to the top of the body whorl only; the groove in the an- 

 terior digitation rather faint; surface of body whorl with two re- 

 volving carinae marking these grooves and covered with faint re- 

 volving lines; aperture small, inner lip with a spreading callus; 

 canal moderate, terminating in a sharp point slightly recurved. 



'"Locality. — Gregg's landing, Ala. 



"Quite common; the digitations are subjecfl to con.sidera]jle 

 variation, the younger forms have only the po.sterior one.
