MICRO VOLUTA. 105 



band over the tubercles, and another, bordered with brown, 

 below the middle of the body-whorl. Length, 1 inch. 



La Paz, Lower Galifornia. 



Not figured ; said to be more slender, with the spire more 

 acute, smaller tubercles and costse, a more prolonged and 

 recurved siphon, and more contracted aperture than L. Gumingii. 

 The surface is not smooth and the color is lighter. 



L. GUILDINGII, Sowb. PI. 31, fig. 148. 



Fulvous, with white and darker lines ; longitudinally ribbed, 

 granose at the sutures. Length, -5 inch. 



/. St. Vincent, West Indies. 



I am not acquainted with the species. 



L. GUTTATA, Reeve. PI. 31, fig. 149. 



White, maculated with brown ; longitudinally plicate. 



Length, '5 inch. 



Honduras. 



Possibly identical with the last species ; if so, it will become 

 a synonym, Guildingii having priorit}^ of publication. 



L. COLUMBELLA, Sowb. PI. 31, fig. 150. 



Small, oblong, smooth, pallid maculated with red ; spire 

 acuminate, aperture elongate ; lip incurved in the middle ; 

 columella very obscurely plicate. Having the form of Colum- 

 bella nitida, and showing rather faint plicae on the columella. 



The above is a copy of Sowerby's description and figure. It 

 is certainly not a Valuta, and appears more like a Marginella. 



Genus MICROVOLTJTA, Angas. 



The deep siphonal notch, and the toothed projection of the 

 base of the pillar, so characteristic of the Yolutes, are absent 

 in this curious little genus. 



M. AUSTRALIS, Angas. PI. 31, figs. 151, 152. 



White, or ornamented with two rows of distant irregular 

 chestnut blotches and zigzag lines, Length, 10 mill.
