outer part of the dorsum or sides, and the flattening of the 

 base. The dorsum may be covered with longitudinal [spiral] 

 ridges until near the basal angle. There are five shells from 

 Kauai in the Boston Society collection, and one shell in 

 Cooke's collection, from Kauai (Hyatt).

The shell is turrited, rather solid, smoothish. The spire 

 tapers slowly, but terminates above in a more rapidly taper- 

 ing cone. The first half or three- fourths whorl is smooth; 

 then rather coarse, curved, vertical ribs set in. On the third 

 whorl these become finer and more or less split into sharp 

 striae. About the middle of the third whorl some shallow 

 spiral sulci appear and part of the striae are cut into oblong 

 granules; at the end of 3y 2 whorls, weak cords appear at the 

 shoulder and close above the suture below; these gradually 

 enlarge into conspicuous angles or keels, the lower one usually 

 covered at the suture except on the last whorl. The verti- 

 cal sculpture gradually diminishes, leaving the last two 

 whorls smooth. The embryonic whorls are bicolored, purple- 

 black and tawny, but the dark lower zone gradually fades 

 as growth proceeds, and is usually narrow or inconspicuous 

 after the 4th whorl. The intermediate whorls of the spire 

 are some shade of tawny brown. A pale zone below the 

 suture begins on the fifth whorl, becoming opaque white on 

 the last two or three whorls. The last whorl is biangular, 

 smooth, and very dark brown or black below the white zone. 



Aperture trapezoidal, bluish white within, with a broad 

 black margin within the thin, acute lip. Columella concave, 

 bluish white with a brown edge, narrowly truncate at base; 

 spiral lamella above the truncation moderate or inconspicuous.
