EUCALODIUM. 9 



Group of E. blandianum. 



E. BLANDIANUM Crosse & Fischer. PI. 5, figs. 23, 24, 25, 26; 

 pi. 8, fig. 21. 



Shell imperf orate, arcuate-rimate, cylindric-tapering, solid; 

 olive, the strice and short transverse wrinkles yelloiv. Surface 

 somewhat glossy, strongly striate obliquely, the strice much 

 narrower than the intervals, slightly arcuate, conspicuous by 

 their yellow color; the intervals more or less malleate. 

 Whorls gradually tapering to the broadly truncate apex, 8 

 being retained in the adult shell; the last whorl convex, the 

 base smoother, defined by a slight narrow carina, scarcely 

 modifying the general convexity except in front. The whorl 

 becomes very shortly free in front. Aperture quite oblique, 

 angularly oval; peristome white, obtuse, narrowly reflexed 

 throughout; columella gently spiral, not truncate or angular. 

 Internal axis (pi. 5, fig. 26) slender and nearly straight. 

 Length 78, diam. above aperture 20 mm. 



Eastern Mexico: Mountains near Orizaba (type locality; 

 Salle, Bland, Botteri) ; rocky country near San Juan Mia- 

 huatlan, between Jalapa and. Misantla, on moist ground 

 among moss and herbs (Dona Estefania) ; Coatepec (Hoge).

Somewhat glossy, yellowish-olive or more or less suffused 

 with brown, generally with the strise and wrinkles yellow, and 

 with some darker oblique streaks. The surface is malleated 

 in places, either in the interstices or involving the strias. 

 Figures 24, 25 are from Crosse and Fischer's type figures, 

 agreeing with specimens before me from Bland. Figs. 23,
