lip ; at the end of the last whorl coarsely striated ; otherwise 

 with excessively minute strias (C. m. var. gracilis C. B. A., 

 Contrib. no. 9, p. 166) . 



No locality is given for this insufficiently-described form, 

 which, with var. Integra, composed Adams' group of " aber- 

 rant slender forms." I have not seen specimens, and rank 

 the form as a species merely because, in the absence of struc- 

 tural details or measurements, I do not know what else to do 

 with it. 



3a. Var. integra (C. B. Adams). 



' ' Shell quite slender ; dull white, with a clear white lip ; 

 stria? very oblique, quite distinct on the last whorl, very 

 minute on the spire. The only specimen before me is not 

 truncated " (C. m. var. integra C. B. A., Contrib. no. 9, 

 p. 166).

3&. A. ADAMSI Pilsbry, n. sp. 



Shell perforate, slenderly fusiform, narrowly truncate, re- 

 sembling A. t. cinerea, pi. 17, fig. 14, in general shape, or a 

 little more attenuate above. Surface glossy, very finely striate 

 throughout, the last third of the last whorl becoming more 

 coarsely rib-striate. Bluish-milky, touched with light brown 

 at the summit; the base, lack of the lip and adjacent surface, 

 broivnish- fleshy. The keel, a subsutural line on the last 

 whorl, and a wide arcuate stripe (behind the fleshy lip-stripe) 

 are opaque-ivhite; and behind the white stripe there is a 

 second fleshy-brown oblique area, fading on its right side into 

 the blue-white ground-color. These colors show within the 

 mouth. The well-expanded lip is flesh-pink and but slightly 

 thickened, somewhat sinuous, and a little retracted at both 

 ends. Columella distinctly truncate in oblique view. Length 

 19.3, diam. 5, length of aperture 4.6 mm., whorls 10.

In the distribution of colors on the back of the last whorl, 

 A. adamsi is not very unlike A. nit ens; but it is a more slen-
