The three-belted Bulimus. Shell somewhat fusi- 

 formly ovate, slightly umbilicated, whorls six in 

 number, convex, smooth, or minutely longitudinally 

 striated ; aperture rather small, lip slightly reflected, 

 pale straw colour, conspicuously belted with thi-ee 

 chesnut zones, lip bright pink.

A chaste and delicately coloured species, not hitherto 



described, in the collection of J. Dennison Esq. 



Species 270. (Fig. a and i, Mus. Dennison ; 

 Fig. c, Mus. Cuming.) 



Bulimus Knorri. Bid. testd fusiformi-ovatd, bast sub-

Knorr's Bulimus. Shell fusiformly ovate, somewhat 

 angidarly produced at the base, largely umbiHcated, 

 whorls seven in number, smooth, beneath the lens 

 minutely transversely striated and indented ; colu- 

 mella broadly reflected ; straw coloiu', or purple-

 edge of the Up pink or deep saffron yellow. 



Pfeiffer, Monog. Hel. viv., p. 95. 



3ab. La Guayra. 



Chiefly distinguished by a peculiar attenuation of the 



apertm-e, and by the deep pink or saft'ron coloiu-ing of the 



lip. The outer colomingof the shell is extremely variable. 



Species 271. (Mus. Dennison.) 

 Bulimus xaxthostoma. Bnl. tedd fmiformi.-ovatd, 

 ampliter umbUicutd, spird ■wbucumiiiatd, anfractibus

 indentatis, columelld late rejlexd, aperturd ovatd, labro 

 late expanso, nix rejlexo ; pallid^ stramined nel auran- 

 tid, apice rosed, labro vivide croceo. 



The yellow-mouth Bulimus. Shell fusiformly ovate, 

 largely lunbUicated, spire somewhat acuminated, 

 whorls eight in niunber, smooth, transversely mi- 

 nutely striated and indented under the lens, columeUa 

 broadly reflected, aperture ovate, lip broadly ex- 

 panded, scarcely reflected ; pale straw colour or 

 orange, pink at the apex and bright safiron yellow

 f. 1, 2. 



Ilab. BoUvia and Santa Fc di Bogota. 



Mainly distmguished from the preceding species by its 

 more acuminated gi'owth, comprising a whorl more, and 

 less oblong form of the aperture. 



Species 272. (Mus. Brit.) 



Bulimus Bairdii. Bui. testd cylindraceo-oblongd, cra&sd, 

 anfractibus septem, plano-convexis, columelld callosita- 

 tibiis grandibus duabus mutiitd, aperturd parviusculd, 

 labro incrassato, rejlexo ; alhd fusco-tinctd, columelld 

 labroqiie ebimieis, apertura fauce croced. 

 Baird's Bulimus. SheU cyUndrically oblong, thick, 

 whorls seven in number, flatly convex, columella 

 furnished with two large caUosities, aperture rather 

 smaU, Up thickened, reflected ; white, stained with 

 brown, Up and columella ivory white, interior of the 

 apertm-e safR-on-yeUow. 



Ilab. ? 



This very interesting shell partakes of the characters of 

 the B. auris-bovina and auiis-Mida;, the latter of which, 

 as may be seen by a comparison of the figiu-e at PL 28, 

 with one in Martyn's Universal Conchologist (sub nom. 

 Helix f brains), assumes very diS'erent aspects, but none 

 with which the present agrees. 



I have the pleasure to name this species in honour of 

 Dr. Baird of the British Museum, as a trifling acknow- 

 ledgment of his great diUgence in sorting the specimens 

 of the national collection, preparatory to their being criti- 

 callv arranged and named. 



October, 1848.
