Cuming's Magilus. Shell elongately-suliglubosc, very 

 minutely aud regularly laminated ; spire rather 

 short, conical, obtuse ; whorls four, the last very 

 large, obtuse in front, aperture large, very oblique ;

Although the sjiire of this species is somewhat 

 conical, the body-whorl is very globose and the outer 

 lip obliquely overlaps its surface to a great extent.

The smael-headed Magilus. Shell with a globose, 

 minute, solid nucleus ; aperture thence suddenly 

 enlarging, produced into an irregular, rugose, 

 tortuous tube, keeled at the canal ; the outer side 

 rugosely striated ; inner side laminately callous, 

 aperture entire, pyriform.

The specimen figured in our plate is the second that 

 has fallen into the hands of its present possessor. It 

 is not named here as a new species without some 

 hesitation, but the minute size of the spiral nucleus 

 and the sudden enlargement of the tubular portion 

 gives the shell so distinct an ajipearauce that the 

 character deserves registering, be it worth what it 

 may.

It is just possible this little glossy shell is but the 

 young of Magilus antiquus.
