BULIMUS.— Plate XIII. 



An interesting new species discovered by Mr. .\rthur 

 Adams, at the above mentioned locality, during the recent 

 e.\pedition of H.M.S. Samarang. " A tree, parti;dly cut 

 through at the base with axes," says the author of the 

 valuable summary of Natural History attached to the 

 Narrative of that Voyage, " feU upon one of the carpenters 

 wooding on the island, depriving liira at the time of sen- 

 sation. What proved a misfortune to the man, however, 

 presented to science a new and beautiful species of BiiU- 

 mus, which I discovered in considerable numbers and 

 variety adhering to the prostrate tree." All the specimens 

 were reversed, of a yeUovv or yellowish green colour, 

 stained with purple rose about the columella, and mostly 

 encircled round the middle by a chain of square greenish 

 spots.
