in large ones. Miller distinguishes a var. elongata (fig. 5), which has 

 a strong columellar tooth, and the last whorl attains only two-fifths 

 the total altitude of the shell. Alt. 90, diam. 34, aperture inside 34 

 mill, long, 18 wide. 



In one of the specimens taken by Herr Stiibel, and recorded by Dr. 

 von Martens, the flames disappear on the last whorl. Reibisch states 

 that one of the 21 specimens collected by Dr. Wolf is 80 mill, long; 

 several of the others being only 60 mill. One specimen is uniform 

 brown, except for the characteristic black spiral lines.

In the form of the aperture this euphoniously named species agrees 

 with 0. yatesi, but the spiral discussating striae and white lips, colu- 

 mella and parietal wall, ally it rather to O.deburghice. Described from 

 a single specimen, now in the Varsovie museum. I am not aware 

 that others have been found. 



O. MAUANHONENSIS (Albers). PI. 41, figs. 3, 4.

 conic, the apex obtuse ; suture with a thread-like margin. Whorls 

 7, a little convex, the first minutely granulated, pale flesh-colored, 

 the last shorter than the spire. Columella callous, white, strongly

 glossy inside ; peristome thickened, narrowly expanded, the margins
