SCHMACKEK AND BOETTGER : CHINESE LAND-SHELLS. 173 



umbilicus is covered by the reflected columellar margin, and tbe last 

 whorl does not descend in front. 



A single specimen of what appears to be a variety of this species 

 was found at Kaochahien, of diam. maj. '26-6, min. 23, alt. 165 mm. 

 Another specimen was brought back by Mr. Bock's expedition, in 1891, 

 from an unknown locality, of diam. maj. 29, min. 23-5, alt. 17 mm. 

 Both differ from the original specimen in having a wider umbilicus, 

 not in any way covered by the columellar margin, and the base of the 

 last whorl — which slightly descends in front — being inflated round 

 the umbilicus, whereas in Heude's specimen it is flattened in the 

 umbilical region. 



Finally, we received from Father L. Fuchs a few specimens (locality 

 Patung?) agreeing with the above variety; the umbilicus is still 

 larger, however. The largest specimen measures diam. maj. 30*5, 

 min. 26, alt. 18 2 mm. and is elegantly granulated — as, indeed, are all 

 specimens of the variety, more or less. This granulation, mentioned 

 by Heude in his description, is absent in the authenticated specimen, 

 although it is in a perfect state of preservation. The type would 

 therefore appear to vary in this respect.
