Plate IV. 



Species 16. (Mus. Cumiug.) 



Ampullakia autumnalis. Amp. testa turbinatd, spird 

 mbprominuld, anfrcwtibm rotundatis, ad suturam de- 

 presdmculis, obscure spiraliter funiculatis, funiculk 

 irregularibus, interstitiis maUeatis et atriatis ; wM- 

 lico mbamplo ; apertura rotundato-ovatd, labro sub- 

 expanso ; olivaced, castaneo-rufo tinctd. 



The autumnal Ampullakia. Shell turbinated, spire 

 rather prominent, whorls rounded, rather depressed 

 at the suture, obscurely spirally corded, cords irre- 

 gular, with the interstices malleated and striated; 

 umbilicus rather large; aperture rotundately ovate, 

 lip rather expanded; olive, stained with chestnut- 

 red. 



Hfth. ? 



The whorls of this species are somewhat more than 

 usually rounded, whOe they are concentrically sculptured 

 with obscure cords, irregular and wrinkle-like in parts, 

 with the interstices malleated and striated. The outer 

 surface is partially covered on the olive ground with a 

 deciduous chestnut-red coating. 



Species 17- (Mus. Cuming.) 



Ampullakia venetus. Amp. testa globosd, subventri- 

 cosd, spird breviusculd, acuta, anfractibus superrii de- 

 clivibus, deinde convexis. utidique malleatis et minute 

 cremdato-striatis ; umbilico mediocri; apertura lu- 

 nato-pyriformi, parviusculd, labro expamo ; luteo- 

 virescente, versus apicem pallidiore, labro lutescente. 



The sea-green Ampullakia. Shell globose, subven- 

 tricose, spire rather short, sharp, whorls slanting 

 round the upper part, then convex, everywhere mal- 

 leated and minutely crenulately striated ; umbilicus 

 middling; aperture lunar-pyriform, rather small, lip 

 expanded ; yellowish-green, paler towards the apex, 

 lip yellowish. 



H„b. ? 



A pale sea-green species, witli the surface ratlier largely 

 malleated throughout and minutely crenulately striated 

 the lip and columella being of a rather conspicuous pale 

 yellow tone. 



Species 18. (Mus. Cuming.) 



Ampullakia urceus. Amp. testd globoso-turbinatd, so- 

 lidiusculd, spird brevi, plerumque plus minus erosd, 

 anfractibus compressi rotundatis, ad suturam depres- 

 siusculis, irregulariter corrugato-liratis, et rugoso-re- 

 ticulatis ; umbilico amplo, prof undo ; apertura pyri- 

 formi, labio columellari rejlexo ; lutescente-albd, epi- 

 dermide crassd earned olivaced indutd. 



The pitcher Ampullakia. Shell globosely turbinated, 

 rather sobd, spire short, generally more or less 



eroded, whorls compressly rounded, a little depressed 

 at the suture, irregularly wrinkle-ridged and ru- 

 gosely reticulated ; umbilicus large and deep; aper- 

 ture pyiiform, columellar bp reflected ; yellowish- 

 white, covered with a thick horny olive epidennis.

Hab. Trinidad; Cutler. 



This well-known species is at once recognized by its 

 compressly rounded form and stout wrinkle-ridged horny 

 epidermis, mostly eroded at the apex. 



Species 19. (Mus. Cuming.) 



A.mpullaria puncticulata. Amp. testd subpyriformi- 

 ovatd, ventricosd, spird mediocri, anfractibus superni 

 tumidis, versus basin attmiuatis, lavigatis, sub lente 

 punctulatis ; umbilico angusto ; apertura oblongo- 

 ovatd, labro columellari reflexo ; olivaceo-virescente, 

 fasciis angustis viridibus obscure pictd, labro aurantio- 

 rufo. 



The punctured Ampullaria. Shell somewhat pyri- 

 formly ovate, ventricose, spire middling, whorls 

 swollen round the upper part, attenuated towards 

 the base, smooth, finely punctured beneath the lens ; 

 umbilicus narrow ; aperture oblong-ovate, columellar 

 lip reflected ; olive-green, obscurely painted with 

 narrow green bands, lip orange-red. 



Swainson, Zoological Illustrations, vol. iii. p. 143. 



Uah. ? 



Of a very characteristic pear-bke ovate form, with a 

 warm orange-red lip. 



Species 20. (Pig. a, b, Mus. Cumiug.) 

 Ampullaria vexilldm. Amp. testd ovatd, tenuiculd, 

 ventricosd, anfractibus convexis, superni subplanulatis, 

 Icevigatis, sub lente punctulatis; umbilico angusto; 

 apertura pyriformi-ovatd, expansd, labro columellari 

 reflexo ; olivaceo-virescente, fasciis saturate viridibus 

 cingulatd, labro rufescente. 

 The flag Ampullaria. Shell ovate, rather thin, ven- 

 tricose, whorls convex, rather flattened at the upper 

 part, smooth, finely punctured beneath the lens ; 

 umbiUcus narrow; aperture pyriformly ovate, ex- 

 panded, columellar lip reflected ; olive-green, encir- 

 cled with dark green bands, lip tinged with red. 

 IM. ? 



Very closely allied to the preceding species, but of a 

 less pear-shaped form, with the whorls more flattened 

 round the upper part.
