HELIX-CAM^ENA. 199 



An abundant and well-known shell. Its geographical range com- 

 prises a considerable portion of central China. Mollendorff says : 

 This species seems to range over the entire province of Guang-dung. 

 I have found it besides in Canton, and the hilly district around it 

 especially in gardens. Missionary Fuchs has traced it from around 

 Liendschou to Canton, but not on the other side of the water-shed in 

 Hunan. On the coast it is lacking at Swatow, has not been observed 

 at Amoy or Fudschou, and according to Heude is not found in the 

 Yangtze Valley. It seems to be absent at Hongkong and the other 

 coast islands, as well as upon the adjacent mainland ; those found in 

 the gardens and parks of Hongkong having doubtless been imported 

 from Canton with plants. The same is true at Macau, where I have 

 seen it in Camoens' garden. At both places only small (dwarfed ?) 

 specimens occur.

 nearly closed. Alt. 32, greater diam. 46, lesser 37 mill. (Mldff.} 



Tshien-ti-shan, province of Gui-dshou, China. 



Var. DUCALJS Ancey. 



Larger than the type ; collumellar lip much more dilated, broadly 

 triangular, more reflexed, everted over the umbilicus, nearly closing 

 it. Shell more strongly malleated above. Diam. maj. 74, min. 67 

 mill. (Ancey.}

H. SERAPHINICA Heude. PL 69, figs. 6, 7. 



Shell large, sinistral, solid, narrowly umbilicated, excavated 

 around the umbilicus ; epidermis brown, encircled by a broad black 

 band above and below the carina, and another narrower one at the 

 suture ; suture excavated ; spire subturbinate, whorls 7, keeled at 

 the suture, the last rapidly increasing, with a thread-like keel at the 

 periphery. Aperture elliptical deflexed, nearly horizontal ; per-
