CARELTA. 117 



The spire widens more rapidly than in C. dolei, and the 

 lower angle is decidedly stronger. In C. cumingiana the sur- 

 face is smoother, the coloration much more brilliant, and there 

 is more sculpture on the first neanic whorl. 



11. C. SINCLAIRI Ancey. PL 16, fig. 8 ; pi. 21, figs. 6, 7. 



Shell subfossil, reddish white or fleshy whitish, with the 

 aperture and part of the last whorl before it usually violet- 

 red; scarcely shining, solid, the young very narrowly per- 

 forate, generally imperforate; oblong-tapering. Spire 

 conoid with subconvex outlines, a little obtuse. Whorls 8, 

 the first 4 smooth, the rest obliquely and closely, subirreg- 

 ularly plicate, upper whorls flattened, the lower a little 

 convex, last whorl ovate, rounded. Suture more or less dis- 

 tinctly margined below, simple above. Aperture suboblique, 

 tapering-oval, narrow above and below, angular above. Colu- 

 mella arcuate, thickened, s-omewhat twisted, obliquely and 

 lightly truncate above the base. Basal margin forming an 

 angle with the columella, outer lip regularly elliptical. 

 Peristome simple, acute, unexpanded. Length 32 to 37, diam. 

 14 to 16, alt. aperture 12 to 14 mm. (Ancey).

"It is distinguished easily by the oval shape, oblong last 

 whorl without angularity, the striation and the general ap- 

 pearance resembling Amastra violacea Newc." 



From the freshness of some of the specimens Mr. Bor- 

 cherding concludes that the species is perhaps still living in 

 some secluded valley in the somewhat wooded interior of 

 Niihau. 



Specimens were distributed many years ago by Dr. Wesley 

 Newcomb under the (unpublished) name Carelia extincta 

 Nc. One of these is figured on pi. 16, fig. 8. The first whorl 

 is smooth, the next very finely striate. While about equal to 

 C. b. adusta in size, this species differs by its less convex, 

 coarsely striate whorls and margined suture.
