the species will be found to attain greater dimensions than 

 that of the type before us. It is handsome, painted with 

 longitudinal close-lying zebrine flames, dark brown on a 

 straw-colored ground, the whole surface of the upper whorls 

 and the upper portion of the last being delicately decussatedly 

 granulose " (M. & P.). 



The species seems related to C. smithii Craven. 



III. Group C. varicosa. 



Thin, light, ovate or obesely ovate shells, usually flammu- 

 late, more or less decussate above, and with a rather large 

 apex. 



17. C. VARICOSA (Pfeiffer). PL 26, figs. 30, 31, 32, 33. 



Shell swollen-ovate (in the young, oblong-ovate when 

 mature), thin, glossy; buff, lightning-streaked with broad, 

 black-brown flames, and irregularly placed blackish varix- 

 streaks. Spire turbinate, obtuse, granulated, the suture 

 slightly crenulate. Whorls (in young shells) 5 to 6, a little 

 convex, the last a little longer than the spire, striatulate, de- 

 cussate with spiral striae under the suture; (but adults have 

 7 slightly convex whorls, the upper minutely granuloseh 

 decussate, the following granulose on the upper half, the last 

 whorl a little longer than the spire, striate, with almost 

 obsolete impressed lines at the suture) . Columella compressed, 

 acute, lightly twisted, narrowly truncate. Aperture sub- 

 vertical, oval, bluish and whitish within, and showing the 

 stripes through; peristome simple, acute, blackish-margined. 



Length 43, diam. 25, aperture 27x16 mm. (Pfr.). 



Length 90, diam. 41, aperture 50x27 to 28 mm. (Pfr.).

Pfeiffer 's first description and figures applied to a specimen 

 (pi. 26, figs. 30, 31) which he afterwards found was im- 

 mature. He writes as follows: When Mr. Hartvig sent me 

 the example described in 1861, he wrote me that larger ones 

 could not be found, and those collected seemed to be full
