BULIMUS.— Plate LXXVII. 



The Lima Bulimus. Shell acuminately ovate, rather 

 deeply umbilicatecl, whorls seven in number, longitu- 

 dinally very closely elevatcly striated, strias irregular, 

 subplicate, columella reflected, lip simple ; pale rusty 

 brown. 



Hab. Lima and Quito, South America. 



This is allied to the B. scalariformis, but does not agree 



with any of the varieties of that species. 



Species 564. (Mus. Benson.) 

 Bulimus Sylheticus. Bui. suhacuminato-ohlongd, soU- 

 dimculd, smistrdi, umbilicatd, anfractihns sex, lavihis, 

 columella lahroque subincrcmsatu, dilatato-rejlexk ; 

 vivide luted, columella labroque palUdioribus. 

 The Sylhet Bulimus. Shell somewhat acuminately 

 oblong, rather solid, sinistral, umbilicated, whorls six 

 in number, smooth, lip and columella rather thick- 

 ened, dUately reflected ; bright yeUow, lip and colu- 

 mella paler. 

 Hab. Sylhet, Eastern Himalaya ; Benson. 



Having very much the aspect of a young or dwarf speci- 

 men of B. citrims, it might easily be confounded with 

 that species. 



Species 565. (Mus. Cuming.) 



Bulimus mollicellus. Bid. testa subajlindraceo-oh- 

 longd, vix imibilicatd, suturis subconstrictis, anfractibus 

 sex, subtilissime irregulariter striatic, ad siituras leviter 

 crenulatis, columella rejlexd, apipressd, aperturd pau- 

 lulum contractd, labro simplici ; pellucido-albd, epkler- 

 mide tenui stramined indutd. 



The delicate Bulimus. Shell somewhat cylindrically 

 oblong, scarcely umbilicated, sutures rather con- 

 stricted, whorls six in number, very finely ii-regularly 



striated, slightly crenulated at the sutures, columella 

 reflected, appressed, apertm-e a little contracted, lip 

 simple ; transparent white, covered with a thin straw 

 coloured epidermis. 



Hab. ? 



A delicate small species certainly distinct from any 



hitherto described. 



Species 566. (Mus. Cuming.) 

 Bulimus transpaeens. Bill, testa acuminato-oblongd, 

 tenuissimd, hand umbilicatd, anfractibus sex, subtilis- 

 sime irregulariter striatis, colmnelld tenuissimd rejlexd, 

 labro simplici ; pellucido-corned. 

 The transparent Bulimus. Shell acuminately oblong, 

 very thin, not umbilicated, whorls six in number, very 

 finely ii'regidarly striated, columeDa very thinly re- 

 flected, lip simple ; transparent homy. 



Hab. ? 



Of as bght and delicate a structure as any Lymnea. 



Species 567. (Mus. Cuming.) 



Bulimus nigrilineatus. Bui. testd conico-ovatd, ven- 

 tricosd, tenuicula, liaud iimbilicatd, anfractibus sex, 

 lavibus, vel, sicb Unte, temiissime striatis, columella 

 tcimiter reflexd, labro simplici ; stramined, lineis mgro- 

 fascis fasciatd. 



The black-lined Bulimus. Shell conically ovate, ven- 

 tricose, rather thin, not umbilicated, whorls six in 

 munlier, smooth, or, beneath the lens, very finely 

 striated, columella thinly reflected, lip simple ; pale 

 straw-colour, banded with black-brown lines. 



Hab. ? 



The bands round the upper part of the whorls are 

 somewhat lighter than those round the lower.
