The following paper contains a complete list of the 

 Mollusks, collected during the travels of Messrs. Biittikofer 

 and Sala (1879—1882), of Mr. Stampfli, sent out by Mr. 

 Buttikofer after his return from Liberia (1884— 1885), and 

 of a second visit to that country by Buttikofer and Stampfli 

 (1886—1887). As the principal intention of the mentioned 

 travellers was to collect vertebrated animals, there was 

 not much time left to bestow upon Mollusks, most of 

 which were collected by Mr. Buttikofer in the country of 

 Grand Cape Mount, where especially all the marine forms 

 were obtained. Full explanations as to the visited localities 

 are given in the introductions to the lists of Birds by 

 Buttikofer (see: Notes Leyd. Mus. 1885, p. 129 & ff. with 

 map; 1886, pp. 243-245, and 1888, p. 59-63 with map). 



The learned Dr. H. Dohrn of Stettin, who obtained 

 ample collections of Liberian Mollusks from his collector 

 Mr. Schweitzer, who explored about the same localities, 

 has kindly assisted me in the determination of some 

 doubtful species, while Dr. A. Brot found three new spe- 

 cies amongst the specimens of the genus Melania.
