SowERBY, Pro. Zool. Soc., 1833, p. 73. 
Hab. Island of Perico, Bay of Panama (on dead leaves) ;

same locality. 
Species 134. (Mus. Cuming.) 
Bulimus corneus. Bui. testa ovatd, subventricosd, um- 
bilicatd, anfract'dms quinque ad sex, rotundatis, leevi- 
bus, aut mitmtissinie striatis, labro simplici; corned, 
pellucidd. 
The horny Bulimus. Shell ovate, somewhat ven- 
tricose, umbilicated, whorls five to six in number, 
rounded, smooth or veiy minutely striated, lip simple ; 
horny, transparent. 
SowERBY, Pro. Zool. Soc., 1833, p. 37. 
Hab. Beal Llejos, Central America (under decayed grass) ; 
Cuming. 
A simple transparent horny shell, the whorls being 
somewhat roimded. 
Species 135. (Mus. Cuming.) 
Bulimus Jacobi. Bid. testd ovatd, subaaminatd, ampliter 
umbilicatd, anfractibus subrotundis, Itsvibus, columella 
supra umhilicimi partim, expansd, aperlurd paroinsculd, 
labro simplici ; corneo-fmcescente. 
The Jacob Bulimus. Shell ovate, somewhat acuminated, 
largely umbilicated, whorls rather rounded, smooth, 
columella partially expanded over the umbilicus, 
apertm-e rather small, lip simple ; pale homy brown. 
SowERBY, Pro. Zool. Soc., 1833, p. 74- 
Hab. Jacob Island, GaUapagos ; Cuming. 
Chiefly distinguished from the last species by its large 
umbilicus, which is not seen in the figure on account of 
its being partially overlaid by the columeUar lip. 
Species 136. (Mus. Cuming.) 
Bulimus Darwinii. Bui. testd subgloboso-ovatd, teuui- 
culd, injlatd, umbilicatd, anfractibus sex, superne sub- 
angulatis, longitudinaliter conspicue riigatis, intersUtiis 
corrugato-striatis, columella subtortd, tuberculis duobus 
callosis prominentibus armatd, aperturd subquadrato- 
ovali, labro simplici ; intus extusque ficlili-brumied. 
Darwin’s Bulimus. Shell somewhat globoscly ovate, 
rather thin, inflated, umbilicated, whorls six in num- 
ber, slightly angulated round the upper part, longi- 
tudinally conspicuously wrinkled, the interstices being 
transversely corrugately striated, columella slightly 
tivisted, and armed with two prominent callous tu- 
bercles, aperture somewhat squarely oval, lip simple, 
earthy brown within and without. 
Pfeiffer, Pro. Zool. Soc., 1846, p. 39. 
Hab. GaUapagos Islands (on bushes) ; Darwin. 
It wiU be observed on comparing this sheU with the 
B. rugiferus and seidpturatus, that a uniform peculiarity 
of wrinkled sculpture prevails in each species ; the present 
is chiefly distinguished by its globose form and by the 
caUosities on the columella.
