ANACHIS. 155 



chestnut spots and zigzag- markings, more or less interrupted by 



the smooth interstices of the ribs ; aperture v;hite within, the 



outer lip sinuous behind, and plicate within. 



Length, 15-18 mill. 



West Indies. 



C. lineolata^ Kiener 'fig. 45), is a synonym, and I suppose 



that C. Galifornica^ Reeve (fig. 46), a species which does not 



inhabit " California," may also be placed here, if the figure may 



be depended on. 



C. Adeline, Tryon. PI. 54, fig. 4t. 



Shell closely longitudinally ribbed, with revolving striae, 

 apparent principally in the interstices of the ribs ; ivory-white, 

 shining, with two broad bands of chocolate spots, arranged in 

 checker-board fashion, and leaving a central band of white; lip 

 with external varix, sinuated behind and dentate within ; aper- 

 ture white. Length (decollated), 15 mill. 



Habitat unknoion. 



Six fine specimens are before me, all of them decollated. The 

 nearest ally is C. Terpsichore,, but this shell differs in its more 

 numerous, less tuberculated ribs, in the disposition of the color- 

 spots and their form. 



C. suFFUSA, Sowb. PI, 55, fig. 49. 



Shell distantly longitudinally ribbed, with shouldered whorls, 

 the ribs sometimes obsolete on the body-whorl, which is striate 

 at the base ; white, with longitudinal streaks and spots of 

 chestnut, often forming interrupted revolving bands. 



Length, 10 mill. 



Galapagos (Wiminer); Central America (Morch). 



C. NiGRicosTATA, E. A. Smith. PI. 55, fig. 50. 



Shell subturreted, longitudinally ribbed; epidermis thin, 

 yellowish ; shell white, the ribs black, bearing a series of white 

 spots a little above the middle of the body-whorl, interstices of 

 the ribs with dark, somewhat zigzag lines, revolving lines at the 

 base spotted with black; aperture white within; labrum dentate. 



Length, 12-5 mill. 



Andaman Islands. 



Appears to be very closel}' allied to G. suffusa, Sowb.
