Ampillaria zonata. Amp. testa mbquadrato-ovatS , 

 tenuiculd, infiatd, anc/usti pro/unde nmbilicatd, spird 

 brevi, acuminata, anfractibus supeme late rotundatis, 

 vltimo basin, versus attetmato ; luteo-olivaced, lineis

Hah. Columbia. 



The shell here figured, the only specimen we have been 

 able to refer to A. zonata, corresponds with the variety 

 figured by Dr. Spix with the name A. Archimedes. 



Species 54. (Mus. Cuming.) 

 Ampullaria vermiformis. Amp. testd globoso-turbi- 

 natd, siibampliter miibilicatd, sjnrd mediocri, anfrac- 

 tibus ad suturam impresse canaliculatis, deinde rotun- 

 datis, snbrude striatic ; lutescente-olivaced, fasciis vi- 

 rescentibus atigustis cingulatd; aperturd circulari- 

 ovatd,fauce aurantio tinctd. 

 The vermiform Ampullaria. Shell globoscly turbi- 

 nated, rather largely umbilicated, spire middling, 

 whorls impressly channelled at the suture, then 

 rounded, rather roughly striated ; yellowish-olive, en- 

 circled with narrow faint green bands ; aperture cir- 

 cular-ovate, interior tinged with orange. 

 Hdb. Paraguay. 



Distinguished from A. insulartim, to which it is closely 

 allied, by its more spirally turbinated growth, larger umbi- 

 licus, and painting of narrow green bands. 



Species 55. (Mus. Cuming.) 



Ampullaria Amazonica. Amp. testd oblongo-omtd, 

 mbanguste profundi umbilicatd, spird exsertd, anfrac- 

 tibus ad suturam impressis, deinde eonvexis, longitu- 

 dinaliter striatis ; virescente-olivaced, obsctire fas- 

 cial a ; aperturd pyriformi-oUongd, fauce aurantio 

 tinctd. 



The Amazon Ampullaria. Shell oblong-ovate, rather 

 narrowly deeply umbilicated, spire exserted, whorls 

 impressed at the suture, then convex, longitudinally 

 striated ; greeiiish-olive, obscurely banded ; aperture 

 pyriformly oblong, interior tinged with orange. 



Hab. Eiver Amazon. 



Closely resembling Mr. Swainson's drawing of A. re- 

 Jlexa, but of larger size and differently coloured in the 

 mouth. 



Species 56. (Mus. Cuming.) 



Ampullakia Cassidiformi. Amp. testd oblongd, ver- 

 sus basin attenuata, subanguste profundi umbilicatd, 

 spird breviusculd, conoided, anfractibus super?ee tu- 

 mido-declivibus, deinde plano-convexis ; lutescente-

 formi-oblongd, fauce livido-pnrpured, labro columel- 

 lari interdum sanguineo Undo. 



The Cassis-shaped Ampullaria. Shell oblong, at-

 brown; aperture pyriformly oblong, interior livid 

 purple, eolumellar lip sometimes tinged with liiood- 

 red.
