Amply distinguished by its extraordinary mode of 



growth, of which an approximation is offered in the 



species which follows. 



Species 359. (Fig. a and b, Mus. Cuming.) 



Bulimus auris-leporis. Bui. testd subpyramidali-ovatd, 

 bad depresso-convexd, umbilicatd, anfractibus sex, sub-

Hab. Brazil. 



The plan of growth and detail of sculptm-e are the same 



as in the B. navicula, in which species they may be said to 

 be fancifully exaggerated. 



Species 360. (Mus. Cuming.) 



Bulimus coarctatus. Bid. testd conico-ovatd, soliduld, 

 umbilicatd, anfractibus sex ad septem, laviAus, aut sub 

 lente subtiliter decussatim striatis; cohimelld incras-

 latiusculo ; albd, superne Uriels interruptis, inferne 

 fasciis, fusco-nigricantibus cingulatd, apice nigro, lahro 

 eburneo. 



The contracted Bulimus. Shell eonically ovate, 

 rather solid, umbilicated, whorls six to seven in

 striated ; columella thickened, reflected, aperture con- 

 tracted, lip flatly expanded, rather broad ; white, 

 encircled round the upper part with brown-black 

 interrupted Hues, round the lower with bauds, Kp

Somewhat Fartula-^Sk^ in aspect, though not possessing 

 the characters of that genus.

Bulimus auris-muris. Bui. testd conico-ovatd, basi 

 depresso-pland, subobscure umbilicatd, anfractihus sex 

 ad septem, planiusculis, Icevibus, stib lente subtiliter 

 malleatis; columella late rejlexd, aperturd lateraliter 

 plano-contortd, subtrigond, labro refiexo ; albd, lineis 

 ccerideo-nigricantibus cingulatd, labecidis pallidioribus 

 obliquis. 



The mouse's-eae Bulimus. Shell conicaUy ovate, 

 depressly flattened at the base, somewhat obscurely 

 mnbilicated, whorls six to seven in number, rather 

 flattened, smooth, finely indented under the lens; 

 columella broadly reflected, aperture flatly contracted 

 at the side, somewhat triangular, lip reflected ; white,

 140. pi. 3. f. 1-3. 

 Otostoma myotis. Beck. 



Hab. Baliia, Brazil. 



Although partaking of the form and minute detail of 

 sculpture presented in the B. navicula and auris-leporis, 

 this is a very distinct and characteristic species.
