that of the proboscis at its point ; it therefore seems that 

 the hole had been enlarged after it was made. Some 

 specimens of M. erinaceus are very much larger than 

 others^ even in the same locality ; in the Mediterranean 

 they attain a comparatively gigantic size. 



The ^' ui'chin-shell " of Pennant, Buccinum porcatum 

 of Da Costa, and perhaps M. cinguUferus of Lamarck, 

 when half-grown it is the M. Tai^entinus of the last- 

 named author. M. clecussatus of Gmelin (from Adan- 

 son) is closely allied, if not identical. M. torosus of 

 Lamarck is, according to the Rev. R. T. Lowe, a variety, 

 probably sculpta ; but most conchologists refer to that 

 species a tropical shell with smooth ridges. Leach 

 called the present species Ocinebra erinacea. What 

 right have naturalists to play such pranks, 



" And nickname God's creatures " 

 in this fashion ?
