The locality of Chitty's unique type was unknown. The 

 figured specimens, collected at Bogwalk by C. W. Johnson, 

 are pale yellow, becoming white on the last whorl, or gray- 

 white throughout. The glossy surface is everywhere plicate- 

 striate, a little more coarsely so on the back of the last whorl. 

 The suture is finely crenulate above. Whorls very slightly 

 convex, the last rapidly tapering to the strong basal angle. 

 The area within the angle is small. Aperture small oblique ; 

 the peristome is thin, white, expanded and narrowly reflexed ; 

 outer margin strongly sinuous; columellar margin arched 

 forward in the middle. The basal margin is somewhat an- 

 gular and noticeably recurved. The columella is abruptly 

 truncate deep within. 19.5 to 20.5 x 5.7 mm., with 8y 2 whorls. 



Well distinguished by the fusiform shape, finely plicate 

 surface, strong basal angle, the absence of bands or streaks, 

 and the small, oblique, angular aperture. It is most nearly 

 related to A. fuscolabris and A. flexuosa. The latter species 

 differs by the greater number of whorls and vertical aperture. 



11. A. FLEXUOSA (Pfeiffer). 



" Shell shortly and deeply rimate, fusiform-turrite, solid, 

 somewhat closely plicate-striate, alabastrine; spire regularly 

 tapering above the middle, the apex shortly truncate; suture 

 crenulated by the plica; 11 whorls remaining, flattened, the 

 last compressed-carinate at the base, somewhat ascending in 

 front. Aperture vertical, oblong; peristome interrupted, the 

 margins joined by an appressed callous, sinuous, the right 

 margin with a weak tooth within [' dextro intus subuniden- 

 tato ']. Length 23.5, diam. 6 mm." (P/r.).

Known to me by the above description only, the italics be- 

 ing my own. Except in the more numerous whorls, the shell 

 would seem to have much in common with A. radiata Chitty. 

 Has Pfeiffer put the tooth on the wrong margin of the aper- 

 ture in locating it in the right margin ?
