 moderately solid; surface lusterless, sculptured with rather 

 coarse and unequal folds and wrinkles along growth-lines, and 

 numerous, minutely beaded spiral threads, 10 to 12 on the

 closer below the acute peripheral keel; second and third whorls 

 with many even, close, nearly smooth spiral threads. Marbled 

 and zigzag-flamed with dark red-brown and white, the pattern 

 becoming more confused on the later whorls; the smooth apex 

 yellowish or fleshy. Aperture whitish or dark within. Peri- 

 stome blunt, yellow at the slightly expanded edge, usually 

 with a reddish submargin. Columella weakly folded, white, 

 reflexed.

Newcombia carinella BALDWIN, Nautilus, xix, April, 1906, p. 

 136. 



A beautiful species, somewhat variable in contour and mark- 

 ing, but otherwise constant in a lot of 21 received from Mr. 

 Baldwin. With the sculpture of N. cumingi it unites the shape- 

 of the plicata group, and is thus a connecting or synthetic form.
