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. 



2. BuLiMUS NiGROPiLEATUS. Bul. testd acuminato-ovatd, sub- 

 ampliter umbilicatd, anfractihus septem, convexis, obtuse sub- 

 rugoso-striatis, columelld verticaliter reflexd, aperturd ovali, 

 labro simplici ; albidd, basin versus obsolete fusco-fasciatd, apice 

 nigro. 



Hab. Chacliapoyas, 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. 



3. BuLiMUS FOVEOLATUS. Bill, testd oblongo-ovatd, tenuiculd, 

 subventricosd, haud umbilicatd, ad apicem obtusd, anfractibus 

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

 punctis oblongis spiraliter lineatim exsculptis, infra suturas pli- 

 cato-crenulatis, apicem versus peculiariter foveolatis, suturis 

 rudibus, anfractu ultimo oblique descendente, columelld latd, 

 depressiusculd, oblique recedente, aperturd oblongo-ovali, labro 

 subincrassato, vix rejlexo ; intense olivaceo-brunned, infra sutu- 

 ras pallide unifasciatd, suturis albidis, columelld labroque cceru- 

 lescente-albis, aperturce fauce iridescent e-lilaced. 



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



This is the species vsrhich Dr. Pfeiflfer has assigned to the Bulimus 

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

 ceus or hcemastoma 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 roimd the upper sutures, re- 

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



4. Bulimus depstus. Bul. testd subacuminato-ovatd, compress^ 

 umbilicatd, anfractibus septem, rotundatis, Icevibus, supernh 

 depressiuscidis, minute plicato-crenulatis, columelld reflexd, 

 aperturd parviusculd, labro simplici, intus extusque ustulato- 

 fuscd, hie illic saturatiore-strigatd. 



Hab. Chachapoyas, Alto Peru ; W. Lobb. 



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

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

 more rounded aperture. 



5. Bulimus scitulus. Bul. testd subfusiformi-oblongd, vix um- 

 bilicatd, anfractibus octo, leviter convexis, Icevibus, columelld 

 parum reflexd, aperturd subangustd, labro simplici; albidd, 

 purpureo-cceruleo tinctd, basin versus ferrugineo-rvfd, lineis 

 subtilibus albis, irregulariter undulatis, creberrimh longitudi- 

 naliter notatd.
