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

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

 teriorly more or less tuberculii'erous, the last very large, somewhat 

 ventricose ; aperture lengthened, posteriorly acuminated, anteriorly 

 rather broad ; outer lip tliickened, shghtly reflected, imier lip ex- 

 tended, forming a rather thick lamina anteriorly ; columella wdth 

 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 liis 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-fusilbrmi, crassiuscula, Isevi, fulvescente, lineis irre- 

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

 lari, anfractibus senis, 3 ad 4 intermediis tubercidato-costatis, iiltimo 

 subtuberculato-costato, nonnunquam Isevigato ; labio externo mar- 

 gine incrassato, columeUse plicis quatuor vahdis. 



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

 irregularly angular chesnut hues ; spire acuminated, ■with a papil- 

 lary apex ; volutions 6, of wliich 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 tliickened j columella with four distiuct 

 folds. 



First described by Swainson ; notwithstanding the assertion in 

 the second edition of Ins Exotic Conchology, we tliink it entitled to 

 rank as a distinct species. Kieiier refers to tins species in liis text 

 as a variety of Magellanica, and in liis plate as a young elongata.

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