varietj'-, with no markings or stains of any kind. It is quite thin and frail, 

 and a trifle smaller than the average size of Kelletti. 



Santa Catalina Island, California. Two specimens only found by me. 



Var. custanea (Plate IV. Fig. 4). Among the numerous patterns of coloring 

 assumed by H. Kelletti, none are more conspicuous than this well marked va- 

 riety. The body whorl is of a deep shiny chestnut-color above the periphery, 

 and becomes lighter as it follows the whorls of the spire to the apex. The 

 band at the peripheiy is quite variable in the different specimens ; it is gener- 

 ally light and well defined above, but below it is irregular, and spreads over 

 the base of the shell more or less. 



Santa Catalina Island, California. This variety is not rare. 



In "Zoe," Vol. I. No. 11, pp. 333, 334, Mr. Hemphill has also thus described 

 several other forms. 



Var. nitida (Plate IV. Fig. 2). Uniform, translucent, shining, dark hom- 

 color, with a poorly defined dark band, coalescing with a poorly defined whit- 

 ish band below it, at the periphery; spire faintly flecked with ashen gray. 



Catalina Island. 



Var. multilineata (Plate IV. Fig. 1). Shell marked by alternate shades of 

 ashen white, chestnut, or brown, arranged in an irregular series of revolving 

 and sometimes wavy lines, with a broader and poorly defined band at the 

 periphery; markings finer beneath than above. 



Var. f rater. Shell of a beautiful, uniform, hom-buff color, sometimes fad- 

 ing into lighter horn-color, with a darker band at the periphery, and numerous 

 faint, alternate revolving lines of ashen or dark horn-color above and below ; 

 generally, not always, Hghter colored beneath, and sometimes with a whitish 

 zone beneath the band at the periphery. 



Var. Californica. The shell is colored with a darker shade of uniform buff 

 than the above, dark band at the periphery, generally uniform in color above 

 and below; sometimes flecked with squarish dots. 



Var. Forbesi. Ground coloring whitish buff, with a revolving series of poorly 

 defined and coalescing lines, bands, and blotches. 



Var. bicolor. Color very dark horn or brownish, flecked with numerous re- 

 volving very fine dots or irregular lines, with or without a very faint band at 

 the periphery. 



Var. tricolor. Irregularly painted with numerous revolving whitish, brown- 

 ish, and chestnut flecks, blotches, and stains, with or without a band at the 

 periphery. 



Var. albida. (See below.) 



Var. albida, a. Milk white ground, very faintly stained with light horn, 

 and with poorly defined and fading lines. 



Mr. Hemphill considers rediraita as a form of Kelletti, (See that species.)
