chesnut, but varying from that colour, through brownish-yellow to nearly white ; spire very short, frequently mucronate at the 

 apex, but sometimes quite obtuse, with a lighter coloured band at the lower edge; which is, however, sometimes very indistinct; 

 last whorl having two belts at the lower part; the upper margin of the superior belt is very constantly nearly white; there is an 

 indistinct groove above the varix; the varix is about half the length of the aperture, white, oblique, and striated; superior 

 extremity of the aperture acuminated, lower end effuse; upper margin of the outer lip generally rather thickened, lower edge 

 sharp, with a single mucronate tooth. 



This is the A. cinnamomea of Swainson, but certainly not of Lamarck, for it neither accords with his description, nor with 

 the figures he cites ; it is the same as I had supposed to be A. marginata of Lamarck, and I readily acknowledge my mistake, at 

 the same time I must assert that it is not the same as Chemnitz X. t. 147, f. 1381, which I am well assured belongs to Swain- 

 son's A. effusa.

Desc. Shell oblongo-ovate, ventricose, dark-chesnut coloured ; spire rather acuminated with a white tip ; last volutions 

 with two basal belts and a groove above the varix ; columellar varix whitish, with a groove on ihe left side and several stria? ; 

 aperture rather acuminated at the upper end, outer lip with a prominent mucronate tooth on the outer edge near the base : a variety 

 occurs that is spread over with a beautiful cream-coloured enamel. 



This species has been mistaken by Swainson for A. ventricosa of Lam., but may be known from it by its having a prominent 

 tooth near the lower edge of the outer lip. The phrase used by Swainson in his character of this species, " outer lip crenated at 

 the base" .is partly owing to the edge of the lip in the specimen he examined being a little chipped, and partly to a slight irregu- 

 larity in its growth.

Desc. Shell ovate, blunt at the point, with a rather short, but thick spire, covered by a thick coat of enamel, which 

 spreads over the superior part of the last volution, and forms on it a broad rufous belt with a white margin ; lower part of the last 

 volution with an impressed line, it has two belts, of which the upper one is rufous, and a groove above the columellar varix: varix 

 white, obsoletely striated, with a deep groove on the left side. Upper part of the aperture rather obtuse, lower extremity notched ; 

 inside white ; columellar lip white, thickened, and spreading over the last volution near the upper end of the aperture : beyond 

 which, on the front part of the shell, is a broad rufous patch : the colour of the body-whorl is pale brown, and there is a broadish 

 white spiral band above the suture, which is covered by the rufous band. 



A very rare species, of which only three or four bad specimens have been brought from the Cape of Good Hope ; the two 

 best of these were in the African Museum, the others in G. Humphrey's collection : none of the specimens are sufficiently complete 

 to shew the tooth at the lower edge of the outer lip, it is, however, probable, from the nature of the groove above the basal varices 

 that when perfect a small tooth may be observed.
