Hah. Andes of Caxamarca, Peru ; W. Lobb. 



Very like a Clausilia in form, and of a silken aspect, arising out of 

 the very close and minute development of longitudinal striae.

Hah. Chachapoyas, Alto Peru ; W. Lobb. 



It is probable, from the faintly-banded appearance of this shell, that 

 this is but the pale variety of a darker type.

 subventricosd, haud umbilicatd, ad apicem obtusd, anfractibus 

 quinque ad sex, convexis, longitudinaliter obtuse plicato-striatis, 

 punctis ohlongis spiraliter lineatltn exsculptis, infra sutiiras pli- 

 cato-crenulatis, apicem versus pecidiariter foveolatis, suturis 

 rudibus, anfractu ultimo oblique descendente, columella latd,

Hab. Vitoe, near Sarma, Alto Peru ; W. Lobb. 



This is the species which Dr. Pfeiffer has assigned to the Btdimus 

 Mahogani of Sowerby, Conch. Illustr. f. .59 ; a species of the B. rosa- 

 ceus or hcemastomu type, of which I can find no description or tidings. 



The species under consideration will be found, on comparison with 

 Sowerby's figure, to be of a more oblong form, more acuminated at 

 the apex, and very peculiarly indented round the upper sutures, re- 

 minding one very much of the indentations m the shells of Phorus. 



4. BuLiMUS DEPSTUS. Bul. tcstd subacuminato-ovatd, compressh 

 umbilicatd, anfractibus septem, rotundatis, Icevibus, supernk

Hab. Chachapoyas, Alto Peru ; W. Lobb. 



A tliin shell, approaching in form and colouring to the Bulimus 

 nux, from which it differs in being of lighter structure, and having a 

 more rounded aperture.
