This extremely rare and valuable shell is said to be brought from 

 the Gulf of Mexico : the few specimens we have seen have measured 

 from 2| to 4 inches in length. Lamarck has inadvertently described 

 the columella as subseptemplicata. 



14. YoLUTA PUNCTATA (pi. liii. f. 89, 90.) Swains. 



Testa subovali, crassiuscula, isevi, paUide fulva, maculis satura- 

 tioribus subquadratis seriatim dispositis, punctisque concoloribus 

 sparsis picta ; spii'a breviuscula, conica, apice obtuso ; anfractibus 

 paucis, ultimo postice tuberculato, tuberculis^parvis ; columellse pli- 

 cis 4, vaKdis_, albis. 



Shell nearly oval, thickish, smooth, pale fulvous, with darker 

 squarish spots disposed in rows, and sprinkled over with dots of the 

 same colour ; spire rather short, conical, with an obtuse apex ; volu- 

 tions few, the last mth small tubercles posteriorly ; columella with 

 4 distinct wliite folds. 



Pirst described and figured by Swainson in liis Zoological Illus- 

 trations, 1st series, pi. 161, from the only specimen liitherto known, 

 which is imperfect. It is in the British Museum. We tliink it 

 nearly related to F. undulata, and that Swainson has made the apex 

 too acute in his figure.
