2 GUDE : LIST OF HELICOID LAND SHELLS. 



work of the Jesuit Fathers of Shanghai " Memoires concernant 

 L'Histoire Naturelle de I'Empire chinois." Next in importance 

 come the collections made by the brothers Kaspar and Lorenz Fuchs, 

 and Zeno Molltner, enumerated and described by Father Vincenz 

 Gredler in twenty separate papers (1878-1900). Further important 

 collections have been made by the Russian travellers Przewalski, 

 Potanin, and Beresowski, whose shells have been described by Dr. von 

 Martens (Mem. Acad. Imp. Sc. St. Petersb., 1882, xxx, p. i),and by Dr. 

 O. F. von MoUendorff (Ann. Mm. Zool. St. Petersb., 1899, p. 46). 

 More recently further collections made by Mr. W. A. Obrutschew, 

 have been described by Dr. Rudolf Sturany (Denkschr. Math. Nat. CI. K. 

 Akad. wiss. Wien, 1900, p. i) ; and collections made by Prof. K. 

 Futterer and Dr. Holderer have been provisionally figured, but not 

 des.cribed, by Dr. A. Andreae (Mitth. Roemer Museum, 1900, No. 12, 

 p. i). Several lesser contributions will be found enumerated in the 

 Bibliography. 



So far as our present knowledge enables us to judge, the 

 greater number of the Helicoids of this region have a limited 

 distribution, notable exceptions are: Cafhaiea faseiola, Drap., which 

 is found over the whole of north, central, and western China as far 

 south as Kiang-su ; C. puloerafrix, Mts., which occurs over the whole 

 of northern China, reappearing in Hu-nan, and will possibly be 

 found on further exploration in the intermediate provinces of Ho-nan 

 and Hu-pe. C. rirhfho/eni, Mts., also occurs over the whole of North 

 China ; and C. ^«"zey/;aM'«/, Mts., in west China, north from Kan-su 

 through Sze-chuen to Yun-nan in the south. The cosmopolitan 

 Euloia mnilariif and its varieties, moreover, inhabit the whole of 

 Central China as far north as Che-kiang, west as far as Sze-chuen, and 

 reappears in the north-west in Kan-su (Sturany), in the variety 

 stiin])soni, Pfr.
