PHASIANELLA. 177 



white callus; umbilical region excavated ; color white, with numerous 

 narrow red revolving, obliquely descending lines. 



Alt. 5, diam. 5 mill. Cape of Good Hope. 



Subgenus Eucosmia Carpenter, 1864. 



"Shell solid, shining, variegated, not nacreous; aperture and 

 whorls rounded ; conspicuously umbilicated ; peritreme scarcely con- 

 tinuous, not callous." type, E. variegata Carp, 



Californian Pro oince. 



No species of Eucosmia have been figured, and I have no speci- 

 mens. My descriptions are taken from the original ones of 

 Carpenter. 



P. VARIEGATA Carpenter, 1864. Unfigured. 



Shell small, smooth, turbinate, bi-ight, outlines of spire convex, 

 variously maculated with rose color and reddish brown; whorls 

 normally 4, very convex, rapidly increasing, the last one produced 

 anteriorly, separated by well impressed sutures; nuclear whorls 

 regular, apex marnmillated ; base rounded ; umbilicus carinated ; 

 aperture scarcely indented by parietal margin, peristome nearly 

 continuous, acute. Alt. '1, diam. '07 inch. 



Cape St. Lucas, L. Cal. 



Var. SUBSTRIATA Carpenter. 



Form as in E. variegata; but whorls, except the nuclear, very 

 delicately striate, the last with about ten striae. 



As the name variegata is preoccupied in Phasianella, it would be 

 better to use the varietal name, substriata, for this species. 



P. PUNCTATA Carpenter, 1864. Unfigured. 



Much larger, more elongated and narrower than E. variegata, 

 and more like a Phasianella, the greater part densely punctate with 

 brown; umbilicus small; Alt. '22, diam. -15 inch: 



Cape St. Lucas. 



P. CYCLOSTOMA Carpenter, 1864. Unfigured. 



Shell small, very obtuse, wide, regular, valvatoid, outlines of spire 

 scarcely convex; pale cinereous, densely punctate or maculate with 

 brownish olive ; apex pale, mammillated ; whorls normally 3, very 

 convex, with deep sutures; aperture scarcely indented parietally ; 

 umbilicus large, subspiral. Alt. -05, diam. -05 inch. 



12 Cape St. Lucas.
