HELTX-SATSUMA. j 



The largest of the Satsumas. Fig. 75 represents Pfeiffer's type, in 

 which the lip is less bent inward above. The specimens before me 

 correspond with fig. 76, and this form with strongly sinuous outer 

 Hp is probably varietally distinct, and may receive the name var. 

 campochilus. 



H. MICROTROCHUS v. Mollendorff. PI. 53, figs. 79, 80, 81. 



Shell openly umbilicated, globose-trochoidal, obliquely plicate- 

 striatulate, decussated with very fine spiral lines, somewhat shining, 

 horny-brown. Spire convex-trochoidal, the apex rather acute. 

 Whorls 7. slightly convex, the last very obtusely angled at the peri- 

 phery, a little deflexed in front. Aperture oblique, rounded lunar, 

 the peristome narrowly expanded, a little reflexed, sinuous ; colum- 

 ellar margin forming an obtuse angle with the basal margin (v. 

 Moell.) 



Alt. 7?, greater diameter 101, lesser 8f mill. 



Alt. 6J, greater diam. 10, lesser 8* mill. 



Alt. 7, greater diam. 9, lesser 8 mill. 



Province Gui-dshou, China. 



H. (Satsuma) microtrochus v. MLLDFF., J. D. M. G., xiii, p. 195, t. 

 6, f. 6. 



Keminds one somewhat of H. lepidostola v. trochospira, but is 

 higher, the last whorl is nearly rounded, and the whorls are more 

 convex. The cuticle, moreover, is rather shining, lacking all trace 

 of cuticular riblets, and the spiral lines are visible only under a 

 strong lens (Mild/.). 



H. TROCHUS v. Mollendorff. PI. 53, figs. 84, 85. 



Shell half-covered perforate, elevated trochiform, acutely keeled, 

 transversely curved-striatulate, minutely granulose, pale horuy- 

 bp~ ,m. Spire regularly conical, the apex obtuse. Whorls 7, nearly 

 flat, the last very slightly descending at the aperture, base very 

 slightly convex. Aperture oblique, angulate-elliptical, the upper 

 margin hardly expanded, outer and basal margins moderately 

 expanded, the columella broadly expanded, slightly reflexed, rose- 

 white. Alt. 13, diam. 11 mill. (v. Moll.). 



Mt. Uling, and west coast of Zebu, Philippines.
