120 AURIS-EUDOLICHOTIS. 



Aperture subvertical, sinuate-elliptical ; columella brownish-pur- 

 ple, with a strong oblique twist ; peristome expanded and rather 

 reflexed, the right margin somewhat sinuous, columellar margin 

 spreading and vaulted over the umbilicus. (Pfr.from spec, in coll. 

 Albers). 



Alt. 43, diam. 15, alt. of aperture, 22 J- mill.

I regard this as a slender and rather small form of A. midas. The 

 locality assigned must be viewed with suspicion. In A. midas the 

 columellar fold is often colored, especially in immature examples. 



A. HAUXWELLI Crosse. PI. 44, figs. 75, 76, 77, 78. 



Shell openly rirnate-perforate, fusiform, moderately solid. Tawny 

 brown, variegated with wide longitudinal groups of crowded, finely 

 zigzag hydrophanous lines. Surface lusterless, sculptured with low 

 oblique rib-strise on the antepenultimate whorl, the last whorl with- 

 out distinct growth-striae, minutely, densely papillose, the papillae 

 small, rather sharp and irregularly scattered (fig. 78, much enlarged). 

 Spire conic, the apex very obtuse ; whorls 4, slightly convex, the 

 last slightly impressed behind the peristome, produced in a narrow 

 rounded extension at base. Suture well impressed, somewhat de- 

 scending toward its termination. 



Aperture over half the alt. of shell, slightly oblique, very narrow 

 and long; produced in a rounded spout below, flesh -colored within. 

 Peristome blackish-purple, narrowly reflexed throughout, the outer lip 

 somewhat sinuous. Columella widened above, the deeply entering 

 fold gently convex. 



Alt. 49, diam. 18* ; alt. of aperture 29 mill.

Through the courtesy of Prof. William B. Dwight, of Vassar Col- 

 lege, I have been able to describe this species from the type and 

 another specimen preserved in the museum of that college. The 

 general contour is that of A. distorta, but the lip is narrow, as in A.
