5. C. HYATTIANA Pilsbry, n. sp. PL 21, figs. 1, 2. 



The shell resembles C. turricula in shape. The embryonic 

 whorls and up to the end of the 4th taper more rapidly than 

 those following. The first S 1 /^ are bicolored and nearly flat, 

 with a sculpture of narrow, curved, axial grooves, separated 

 by much wider intervals. They are somewhat worn in the 

 type. The rest of the whorls are rather weakly and about 

 equally convex, with sculpture of faint growth-wrinkles and 

 indistinct traces of fine, dense, wavy spiral striolation. The 

 color of the post-embryonic whorls is fallow or tawny yellow; 

 this deepens to a rich chestnut and then dark reddish chest- 

 nut on the last whorl, which is darkest basally. A rather 

 narrow (about 1.5 mm.) snow white zone borders the suture 

 below, on the last five whorls. The aperture is ovate. Colu- 

 mella vertical, brown, with a very weak basal truncation and 

 no noticeable spiral lamella. 



Length 54, diam. 17.2, length of aperture 17 mm. ; whorls 9.

This species is based upon a fossil shell which was asso- 

 ciated with C. dolei in the collection, and which evidently 

 came from the same formation. It differs from C. dolei in 

 wanting an angle or carina at the shoulder at all stages of 

 growth. On the last whorl there is an obtuse but quite ap- 

 preciable basal angle, which, with its shorter aperture, serves 

 to differentiate this species from C. pilsbryi Sykes. 



Compared with C. turricula, this species is less robust at 

 all stages of growth ; the columellar twist is weaker, and the 

 coloration different. 



C. olivacea Pease may be identical with this shell, but the 

 proportions, from Pease's measurements, must be much more 

 slender. The var. variabilis of Pease, of the same length as 

 hyattiana, is wider and has two whorls less.
