Species 109. (Mus. Hanley.) 



Ampullaria Lakgtllierti. Amj). lestd ovato-glohosd,

Largilliert's Ampullaria. Shell ovately globose, nar- 

 rowly umbilicated, rather thin, spire obtuse, whorls 

 rounded, concentrically plicately striated; olive-green, 

 encircled with blackish linear bands ; aperture ovate,

Hab. Madagascar; Largilliert. 



This shell, which we take to be Dr. Philippi's A. Lar- 



gilUerti, is the nearest allied to A. Layardi from Ceylou. 



Species 110. (Pig. «, h, Mus. Metcalfe.) 

 Ampullaria bilineata. Amp. testa globosd, teniii, snb- 

 inflatd, vix umbiUcatd, spird brevi, obtnsd, anfractibus 

 convexis, lievibus, nitentibus ; limdo-fidvesaente,fasciis 

 bilinearibus rufis duabus didantibus cingulatis ; aper- 

 tiird ovatd, labro subeffuso. 

 TuE two-lined Ampullaria. Shell globose, thin, ra- 

 ther inflated, scarcely umbilicated, spire short, obtuse, 

 whorls convex, smooth, shining ; livid-fulvous, en- 

 circled with two distant red bi-lincAr bauds; aper- 

 ture ovate, lip slightly effused. 



Hab. ? 



An interesting species from the collection of Mr. Met- 

 calfe, light and globose, with a smooth, shining, livid- 

 fulvous surface, encircled round the centre with a band of 

 two reddish lines, and the same at the base. 



Species 41. (Fig. b, Mus. Hanley.) 



A fine characteristic specimen of the shell which we 



ventured to determine at PI. IX. Sp. 41, to represent A. 



famiata. 



Species 111. (Mus. Hanley.) 



Ampullaria depressa. Amp. testd ovatd, snbventncosd, 



iviperforatd, spird breviiisculd, anfractibus convexis, 



superiie subplamdatis ; Infco-olivaced, lineis viridibtis 



cingulatd; aperturd oblongo-ovatd, ad basin subsinuaid. 



The depressed Ampullaria. Shell ovate, subventri- 

 cose, imperforated, spire rather short, whorls convex, 

 rather flattened at the upper part ; yellowish-olive, 

 encircled with green lines ; aperture oblong-ovate, 

 somewhat sinuatcd at the base. 



Say, Exped. S. Peters, vol. ii. p. 264. 



ffab. ? 



This species differs from S. paludosa of the same author, 



in being of a lighter and more inflated structure, rather 



attenuated towards the base ; it is of a yellow-tinged olive 



colour, encircled witli green lines. 



Species 112. (Mus. Hanley.) 



A.MPULLARIA BUSEA. Amp. testd ovatd, subventricosd, ad 

 basin attenuatd et effusd, imperforatd, spird brevius- 

 culd, anfractibus superne subdeclivibus, deinde plano- 

 convexis ; fmcescente-ftdvd, lineis numerosis rufo-oU- 

 vaceis cingulatd; aperturd oblongo-ovatd. 



The box Ampullaria. Shell ovate, subventricose, at- 

 tenuated and effused at the base, imperforated, spire 

 rather short, whorls rather slanting at the upper 

 part, then flatly convex ; brownish-fulvous, encircled 

 with numerous reddish-olive lines ; aperture oblong- 

 ovate. 



Hab. ? 



Resemiiling the former species in the contour of the 



aperture and absence of umbilicus, but more slanting ;md 



inclined to angularity next the suture. 



Species 113. (Mus. Hanley.) 



Ampullaria Hanleyi. Amp. testd turbinatd, tenid, 

 pellucidd, anguste umbiUcatd, spird ampliter exsertd, 

 anfractibus rottindatis, subangustis, ItBvibus; livido- 

 fnlvd, lineis rufescente-fuscis cingulatd; aperturd par- 

 viusculd, snbcirculari, labro columellari rejlexo. 



Hanley's Ampullaria. Shell turbinated, thin, trans- 

 parent, narrowly umbilicated, spire largely exserted, 

 whorls rounded, rather narrow, smooth ; livid-fulvous, 

 encircled with red-brown lines ; aperture rather small, 

 nearly circular, columeUar lip reflected. 



Uab. ? 



A semi-transparent turbinated species, quite distinct 



from any that has preceded it.
