AMPULLARIA. 



Plate X. 



Species 45. (Mus. Cuming.) 

 Ampullauia Oronocensis. Amp. testa globosa, am- 

 pliter perspective umbilicata, spird ireviuscula, an- 

 fractibus mtperne impresso-planis, deinde rotundatk ; 

 intense olivaceo-virente, fasciis angustis nigris cingu- 

 latd ; aperturd pyriformi-ovatd, labro irdus intense 

 a urantiO'sangu ineo . 

 The Oronoco Ampullaria. Shell globose, largely per- 

 .spectively urabilioated, spire rather short, whorls 

 impressly flattened at the upper part, then rounded ; 

 dark olive-green, encircled with narrow black bands ; 

 aperture pyriformly ovate ; lip deep orange, blood- 

 red within. 

 ZiEGLER, Mus. Cuming. 

 Hab. River Oronoco. 



Of very characteristic helicoid growth, forming a large 

 perspective umbilicus, distinguished by its vivid colour- 

 ing. The outer surface of the shell is painted with narrow 

 black bands upon a rich olive-green ground, whilst the 

 aperture is stained with blood-red passing into orange.

 Hab. Calcutta (in the Botanic Gardens) ; Benson. 



Peculiarly distinguished by its shining, olive, malleated, 

 globular form and thickened peritreme. The specimens 

 being more or less smooth or wi'inkled, with Fig. 46 and 

 47, represent the extreme states of the species, the spire 

 more or less acuminated and the umbilicus larger or 

 smaller. 



Species 46. (Fig. 46 and 47, Mus. Cuming.) 

 A.MPUELARIA GLOBOSA. Amp. testd rotundato-globosd, 

 aiiguste profundi umbilicatd, spird brevi, obtusd, in- 

 terdum sulexsertd, anfraclibtis rotundatis, lesvibus, ni- 

 tentibus, phis minus malleatis ; lutescente-olivaeed, vix 

 fasciati.i ; ajjerturd lunalo-oblongd, ampld, labro in- 

 crassato, Jlavesceitte. 

 The GLOBOSE Ampullaria. Shell rotundately globose, 

 narrowly deeply umbilicated, spire short, obtuse, 

 sometimes a little exserted, whorls rounded, smooth, 

 shining, more or less malleated; yellowish -olive, 

 scarcely banded; aperture lunar oblong, large, lip 

 thickened, yellowish.

Species 48. (Mus. Cuming.) 



Ampcllaria ampullacea. Amp. testd pyriformi-glo- 

 bosd, basin versus attenuatd, anguste compresse um- 

 bilicatd, spird brevi, obtusd, anfractibus superne decli- 

 vibus, deinde plano-convex is, lavibus ; castuneo-oli- 

 vaced, fasciis angustis nvmerosis cingulafd ; aperturd 

 pyriformi-oblongd, ampld, labro intus aurantio-rufu 

 plu^ minus tincto. 



The jug Ampullakia. Shell pyriformly globose, at- 

 tenuated towards the base, narrowly compressly 

 umbilicated, spire short, obtuse, whorls slanting 

 round the upper part, then slightly conve.K, smooth ; 

 chestnut-olive, encircled with numerous narrow 

 bands ; aperture pyriformly oblong, large, lip more 

 or less tinged within with orange-red.

Hab. Borneo. 



This appears to be the old Liunean type of the genus 



so far as it is possible to determine it. The shell is chiefly 



distinguished by a characteristic globosely pear-shaped 



form.
