EUHADRA LUHUANA Sowb. 1839. (Beechey's Voy., ZooL, Moll. p. 



143, t. 35, f. 4. KOBELT, Fauna Jap. p. 27, t. 3, f. 5-7 ; t. 5, f. 



8 ; t. 6, f. 1-9). 



In its typical development this form differs from typical peliom- 

 phala in the flatter spire, less oblique, less transversely widened 

 aperture, the altogether stronger and rougher shell. It is brown, 

 with a single narrow blackish band ; umbilicus dark or light. Alt. 

 20, greater diam. 41, lesser 35 mill. 



The periphery is obtusely subangulated above the middle. Spec- 

 imens smaller than above indicated, and of a clear yellow color, lip 

 white, are numerous. They have no umbilical spots or bands. 



? Var. EGA Crosse, 1868, (see p. 98). This seems to differ in being 

 more depressed above than typical luhuana, but is probably a 

 variety of that species. 



Sanded but not conspicuously obliquely streaked ; bands 



sometimes spotted. 



Var. PELIOMPHALA Pfr. 1850. 



The type of peliomphala as represented in Fer. Hist, is a shell 

 like figs. 1, 2 of pi. 30, but without spots or streaks on the bands, 

 which are 4 in number, inclusive of the black umbilical patch. 

 Specimens with spots on the bands (pi. 30, figs. 1-4) are more 

 frequent. Specimens with continuous bands usually lack the superoir 

 narrow one (shown in fig. 2, pi. 30.) The spire is rather low. The 

 sculpture is finer, smoother than in typical luhuana, and the aper- 

 ture is wider. 



Form typica. Bands 2, 3 or 4 (incl. umbil. spot), continuous, not 

 streaked or spotted with yellow. Shell more depressed than var. 

 callizona. 



Form maculata. Bands 1-4, maculated with yellow ; umbilical 

 spot present or absent. 



Form cornea. Bandless, yellowish-corneous, usually with a pink- 

 ish streak on the body-whorl, marking the place of a former peri- 

 stome ; spire elevated, conical, sutures impressed ; lip violet-pink, 

 umbilicus rapidly narrowing. Alt. 24, diam. 33 mill. 



Kioto, Japan. 



Var. CALLIZONA Crosse, 1871 (see p. 105). Smaller, much more 

 elevated, with narrow umbilicus ; banded, the bands not interrupted 



by flecks or streaks of yellowish. It sometimes lacks bands, but
