nearly flat, the last as long as the spire, narrowed and com- 

 pressed at the base. Columella subnodose. Aperture oblong, 

 narrowed by the calloused lip ; peristome brownish violaceous,

The descriptions of Reeve and of Pfeiffer are given above. 

 The type specimen is represented by fig. 21, copied from 

 Reeve who described the species in advance of Pfeiffer. The 

 figure measures about 24 mm. long. The last whorl is dark 

 chestnut colored. 



Three specimens received as P. compressa from Mr. Cuming 

 in 1862 are before me, two being figured, pi. 41, figs. 19, 20. 

 The shell is glossy, with very fine and rather weak spiral 

 striation. The color in one shell is white under a yellow 

 cuticle, closely streaked with olive-yellow, the streaks form- 

 ing an ill-defined median belt. The other specimens are very 

 finely, closely but irregularly streaked with brown, on a 

 yellow ground on the last whorl, giving a rather bright red- 

 dish or yellowish brown appearance, while the spire is dull 

 or liver brown, the apex dull purplish-brown. The last 

 whorl is very conspicuously compressed laterally, flat there 

 in the last half-whorl. The aperture is diagonal, the base 

 thrown out from the middle, in the type figure and in the 

 yellow shell before me (fig. 19), but in a smaller shell it is 

 normal in shape. The lip is reflexed, heavily thickened 

 within. The interior is white. 



Length 21, diam. !!% aperture 12 mm., whorls 5%. 



Length 191/2, diam. IQi/o, aperture 10.2 mm., whorls 5%. 



These specimens agree perfectly with one received from 

 Andrew Garrett as P. stolida, and which he figured in Journ. 

 A. N. S. Phila. ix, p. 70, pi. 3, fig. 58. I have drawn this
