NOTE ON THE VARIETIES OF EPIPHRAGMOPHORA MORMONUM. 



i;v n. A. IMLSHKY. 



In (renting of this species both Binney and Stearns have com- 

 mented on its variability. In examining the series in our collection 

 it appears to me that three well-marked races or subspecies exist, 

 which may be readily distinguished. 



Typical mormon u in is large and depressed, pale reddish corneous, 

 often fading to a paler tint on the base ; the brown girdle is conspic- 

 uously darker, and broadly bordered with white above and below. 

 Surface glossy, sculptured with growth-wrinkles only, or if spiral 

 stria- are present they are very faint ; apex minutely granulose. 

 Diam. 29-31, alt. 14-1,') mm., sometimes smaller. Whorls (>. 



Mormon Island, in the American River, Sacramento Co., Cal. 

 (type locality); Tnolumne Co. (Hemphil!). 



Binney's figures represent Pfei tier's type. 



Var. ctt/fi, n. v. Smaller and less depressed ; dark reddish brown, . 

 the peripheral girdle not conspicuously darker, yellow-bordered ; sur- 

 face sculptured with dense minute spiral striae ; whorls 5^;diam. 22, 

 alt. 14 mm., or diam. 2<>,alt. l~> mm. Types from Big Trees, Cala- 

 veras co., Cal.; Fred. L. Button. H. Hemphill. 



Much commoner in collections than the pale, glossy typical form. 



Var. butfoni, n. v. Color as in var. cala, but shell more depressed, 

 periphery more or less carinated in front, the surface studded with 

 minute prominences which bear rather long golden-brown hairs when 

 nnrubbed ; granulation of the apex more strongly developed. Whorls 

 ;H. Diam. -22-24, alt. lH-12 mm. 



Nassau Valley, Calaveras Co., Button. Redding, Shasta. Co.; 

 McGregor. Probably some larger shells collected by Hemphill at 

 Cave City, Tuolumne Co., belong to this variety, but the specimens 

 before me are in poor condition. The largest measures 29 mm. diam. 



This variety forms a transition to E. /ti/lebrandi, which is only an- 

 other term in the variation series, as Stearns has already remarked. 



A NEW CALLIOSTOMA FROM FLORIDA. 



I'.Y IIKNHY A. IMLSBKY. 



Calliostoma Veliei ". >i>. 



Shell imperforate, high-conic, moderately solid, white, with a series 



of small, reddish macula- at the periphery of each whorl. Whorls
