As to the. relationship of the (ialai^ajios Bulimi to many of the forms 

 inhabiting varions snbregions in the general one of the South Amer- 

 ican main, compare /?. hilineatits Sby. in lleeve, No. 132, from "St. Elena 

 and west ( -olnmbia," with certain aspects of rugulosvs lieeve's No. 

 121. Witlumt making an exhaustive or even systematic search for 

 analogies in form, sculpture and general facies, a random reference 

 includes such species as jniHtulom^; Brod., rhodacme Pfr., and iminformu 

 Brod., from Iluasco; pruinosus Sby., and scalariformis Brod., from 

 Peru; modestus Brod., aJhivmis Brod., affinin Brod., arroHUs Brod., and 

 punctuHfer from Chile; striatns King and striatnlus of Sby., montivugus 

 Orb., Bolivia; sordidus Lesson, apodometes Orb., Lmirentii Sby., Chile 

 and Peru, and Ihtumoicna, Orb., also from Peru; Torallyi Orb., tro- 

 choides Orb., and crepundia Orb., thrc^e Bolivian forms. But it is 

 not simply to these as figured in the monographs, but to the shells 

 tliemselves that attention is called; many of the species above named 

 it would be (]uite impossible to lepresent satisfac^torily by one, two, or 

 three figures, or by the same number of examples; the variation whi(;h 

 many of them exhibit is so great, that a large series is absolutely 

 necessary. 



It will be noticed that the mainland forms suggested by me for com- 

 pariscm with the Galapagos shells are principally Chilian and Peruvian; 

 from thelormer especially. It w(mld seem so far as the Bulimoids are 

 considered, that the islands were stocked from this i)art of the conti- 

 nent rather than from Ecuador and farther north. 



RETBISCH'S WOLF COLLECTION. 



Die conchyliologische Fauna der Galai)ag(js-rnseln, von Paul Rei- 

 bisch (mit Tafel i und ii),* includes the following, being an annotated 

 and descriptive catalogue or summary of the terrestrial species pre- 

 viously described and of others regarded by the author as new and 

 described as such. The nuiterial which Eeibisch had before him was 

 collected by Dr. Theodor Wolf, State geologist of Ecuador, but the 

 number of examples seems to have been exceedingly limited and gen- 

 erally in an unsatisfactory condition ; either immature, weathered, or in 

 some other way imi)erfect. 



For the sake of continuity I have quoted herein from Reibisch's 

 ])ai)ers all of the previously described species which he has included, 

 following his numbers, though in some cases he has added nothing to 

 our i)revious knowledge. In other instances the information he has 

 given as to station, altitude, etc., is of sufficient interest to make the 

 publication desirable.
