ANCIIXARIA. 8. 59 



yet approaching A. ampla, with a much shorter varix than either. 

 Unique as far as known. 



6. ampla, Gmel. — Candida, Lamk. — A. elongata, alba seu 

 pallide cinnamomea; spira acuminata; apertura ad basin lata, 

 effusa; sutura inferiori dentifera, balteo inferior! simplice; varice 

 elongato, oblique striato (f. 26, 29). — With a more produced 

 spire than either of the preceding, but with the aperture wide at 

 the base. Both varieties common. 



7. albisulcata, Soivb. Sp. — Caffra, Forsch. ? — A. oblonga, 

 ciunamomea, ad spiram liueis albis cincta ; spira brevi, setate 

 valde calloso-rotundata ; sutura inferiori dentifera, albo margina- 

 ta, balteo inferiori simplice; varice tortuoso, sulcato (f. 39, 40, 

 41). — The spire is sometimes rendered obtuse and rounded by a 

 thick deposit of enamel. The spiral and basal sutures are white. 

 Common. 



8. cinnamomea, Lamk. — A. oblonga, castanea seu pallide cin- 

 namoinca, supra albo-fasciata ; spira subproducta, ad suturam 

 rufo-cincta ; apertura oblonga, infra unidentata, effusa, ad basin 

 emarginata ; sutura inferiori alba ; varice columellari tortuoso, 

 crasso, striato, fulvo (f. 33, 34, 35).- — This shell, to which Mr. 

 Swainsou applied the name A. effusa, and which is figured under 

 that name in the ' Species Conchyliorum,' seems to me to agree 

 perfectly well with Lamarck's description of ciunamomea, the 

 brown varix mentioned by Lamarck not being found in the shells 

 figured for A. ciunamomea in the " Species." 



9. albofasciata, Swains. — A. oblonga, ventricosa, A. ciuna- 

 momea similis sed fulvo-aurantia, magis ventricosa; varice albo (f. 

 36). — The A. ciunamomea is more straight-sided than this species, 

 which is of a light orange-colour, and has a white varix. It is 

 not without hesitation, however, that I admit the specific value of 

 these distinctions. 



10. acuminata, Sowb. Th. — A. elongata, ciunamomea seu alba, 

 intus pallide fulva ; spira exserta, acuminata; sutura callosa ; ulti- 

 mo anfractu subangulato ; sutura inferiori alba, balteo inferiori 

 simplice, castaneo ; varice crasso, tortuoso, striato ; apertura ob- 

 longa, infra unidentata (f. 66, 67). — An angle in the last whorl 

 gives a pyramidal form to the spire, which is also characterized 

 by a slight rising round the whorls at the suture. The sides of 

 the shell are rather straight. In other respects it is like the 

 more acuminated specimens of A. albisulcata.
