lour ; spire acuminated, with a small papillary apex, consisting of 

 two volutions ; the remaining five volutions rather ventricose, pos- 

 teriorly more or less tubereuliferous, the last very large, somewhat 

 ventricose ; aperture lengthened, posteriorly acuminated, anteriorly 

 rather broad ; outer lip thickened, slightly reflected, inner lip ex- 

 tended, forming a rather thick lamina anteriorly ; columella with 

 from four to six irregular, mostly distinct folds. 



A variety of this species, more or less free from tubercles, has 

 been described as a distinct species by Swainson, under the name of 

 elongata, in his Exotic Conchology. Mr. Broderip has proved by 

 a careful examination of a number of specimens that it is only a 

 variety, see Zool. Journ. vol. v. p. 332.

 of Science, xvii. p. 32. 



Testa oblongo-fusiformi, crassiuscula, lsevi, fulvescente, lineis irre- 

 gularibus, angulosis, castaneis, picta ; spira acuminata, apice papil- 

 lari, anfractibus senis, 3 ad 4 intermediis tuberculato-costatis, ultimo 

 subtuberculato-costato, nonnunquam laevigata; labio externo mar- 

 gine incrassato, columellas plicis quatuor valichs. 



Shell oblong, fusiform, thickish, smooth, brownish yellow, with 

 irregularly angular chesnut lines ; spire acuminated, with a papil- 

 lary apex ; volutions 6, of which the 3 or 4 intermediate are longi- 

 tudinally ribbed and posteriorly tuberculated, the last sometimes 

 smooth, sometimes having the same character as the intermediate 

 ones ; edge of the outer lip tluckened ; columella with four distinct 

 folds. 



First described by Swainson ; notwithstanding the assertion in 

 the second edition of his Exotic Conchology, we tlnnk it entitled to 

 rank as a distinct species. Kiener refers to this species in his text 

 as a variety of Magettanica, and in his plate as a yoimg elongata. 

 From New Zealand.

Testa ovato-oblonga, lrevi, tenuiuscula, fulva, lineis angulation 

 undulatis maculisque castaneis notata; spira brevi, obtusa, apice 

 papillari ; anfractibus 4^, ultimo maximo ; labio externo postice ver-

Shell oblong-ovate, smooth, rather thin, Math chesnut spots and 

 angular undulated lines ; spire short, obtuse, with a papillary apex ; 

 volutions 4-j-, the last very large ; outer lip extending up toward the 

 spire posteriorly ; columella with 2 distinct folds in front. 



An exceedingly rare species from Algoa Bay, South Africa. It
