Parti. PHILIPPINE LAND SHELLS BARTSCH. 5 



The same year Zur Mollusken Fauna der Sulu Inseln, by Otto 

 Franz von Mollendorff, was published. 1 On pages 210 and 211 

 Amphidromus roeseleri is described from Sulu Island, and the variety 

 of A. maculiferus mentioned, described, and figured by Smith from 

 Bilitan Island, mentioned in the last reference, is described on 

 page 211. 



A year later Edgar Albert Smith's paper On a Collection of Land 

 Shells from Sarawak, British North Borneo, Palawan, and other 

 Neighboring Islands 2 appeared. In this he lists Amphidromus 

 quadrasi Hidalgo (on pp. 98-99) from Candaraman, and A. entobap- 

 tus Dohrn (on p. 99) from Palawan. 



In 1896 the genus Amphidromus was subjected to a critical revi- 

 sion by Hugh Fulton in A List of the Species of Amphidromus 

 Albers, with Critical Notes and Descriptions of some Hitherto IJn- 

 described Species and Varieties. 3 In this (p. 67) he refers Amphi- 

 dromus chloris Reeve to A. perversus Linnaeus or a subspecies, and 

 A. entobaptus Dohrn is also considered a subspecies of A. perversus 

 Linnaeus. Amphidromus maculiferus and varieties gracilior Fulton, 

 strigata v. Mollendorff, and obscura Fulton are described from 

 Mindanao; while variety inflata Fulton is referred to Philippine 

 Islands without specific locality. Variety multicolor Mollendorff is 

 listed from the island of Leyte (pp. 74 and 75), and Amphidromus 

 roeseleri Mollendorff described (p. 75) from Bilitan Island. 



Amphidromus quadrasi Hidalgo is reported from Balabac Island 

 (p. 85), and A. q., variety solida Fulton, is described (p. 86) and 

 figured (pi. 5, fig. 16). 



Amphidromus versicolor Fulton, described (p. 86), embraces 

 part of the complex referred to by Smith* as varieties of A. quad- 

 rasi. Amphidromus dubius Fulton is diagnosed (pp. 86 and 87) and 

 figured (pi. 6, figs. 1, la) and comes from Balabac Island, while 

 Amphidromus everetti Fulton, also a member of the A. quadrasi 

 complex described as a variety of that species by Smith B as coming 

 from Palawan, is given specific rank on page 87. 



In the same year R. P. Fr. Casto de Elera published the third 

 volume of his Catalogo Sistematico de toda la Fauna de Filipinas. 

 On pages 617 and 618 he lists A. chloris Reeve from Mindanao, 

 Basilan, and Mindoro; A. maculiferus Sowerby from Bohol, Camo- 

 tes, Leyte, Maasin, Bato, and Mindanao, and Amphidromus variety 

 multicolor Mollendorff from Leyte, Maasin, Bato, and Camotes. 



To Amphidromus contrarius Muller the rather large range of 

 Luzon, Balabac, and Timor is assigned.
