 two or tlu-ee folds. 



Distinguished from Y. Ancilla by its much more elongated shape ; 

 the number of folds on the columella is variable as in that species ; 

 they do not, however, appear to be so numerous in tliis.

28. VoLUTA Beasiliaka (pi. liv. f. 98.), Sol., MSS. 



Testa ovata, ventricosa, crassiuscula, glabrata, fulvescente, 

 immaculata; spira brevi, papillari, papilla angusta; anfractibus 

 quinis, ultimo maximo, inflato, postice subangulato, nodifero ; aper-

 yellow, without spots ; spire short, papillary, papilla narrow ; volu- 

 tions 5, the last very large, inflated, posteriorly subangular and 

 tuberculated ; aperture wide ; columella with two folds. 



This appears to be a rare species ; it is found on the coasts of 

 Brazil ; we have never seen it in good coiuhtion though we have 

 occasionally met with the remains of an epidermis, which is very 

 tliin and deciduous, and of a dirty brown colour.
