This species was based on dead examples, presumably fossil. 

 There is a superb set of 91 shells from sand dunes along the 

 shore, Haena, northern Kauai, in the collection of Mi 1 . 

 C. M. Cooke. It is a, highly variable form, closely related 

 to C. cumingiana, from which it differs by the more slender 

 spire, the generally weaker basal angle, and the weaker de- 

 velopment of minor spirals on the neanic whorls. 



The upper angle or keel begins on the fourth whorl (pi. 

 16, fig. 10) ; it varies widely in degree of prominence, and 

 sometimes becomes subobsolete on the last two or three 

 whorls. In a few cases it is doubled (pi. 18, fig. 3). The 

 basal angle is usually rounded off, and seems never to be so 

 strong as in C. cumingiana. The more minute surface- 

 sculpture is like that of cumingiana, except in the weaker 

 spirals. As in cumingiana the fiat, sloping shoulder is often 

 weakly plicate ; otherwise the later whorls appear smooth un- 

 der the lens. 



The specimens are in large part bleached, but many show 

 color. The first four whorls are usually purplish with a 

 narrow subsutural white border. This color fades to white 

 on the following whorls. The last two or three whorls are 

 chestnut, the base darker, with a wide white zone below the 

 suture. This zone includes the shoulder-keel, thus differing 

 from C. cumingiuna' in which the white zone lies above the 

 keel. In a few examples the early whorls are white. Several 

 shells in which the upper carina is weak on the later whorls, 

 want the subsutural white zone. They are chestnut-colo-red, 

 paler just below the suture and in the upper part of the spire ; 

 apical whorls either pale or dark, (fig. 4). This seems to be 

 the typical color form, described by Ancey. 



The specimens figured measure as follows:
