POPULAR CONCHOLOGY. 



Ommastrephes. D' Orb. — Shell, a pen, which is horny , 

 slender, curved, and with three diverging ribs. Animal, 

 body cylindrical, pointed, with large broad fins at the end ; 

 arms with two rows of suckers ; tentacula with four rows ; 

 eyes naked. — 1 4 species. 



These animals abound in most seas, where they are 

 preyed upon both by fish and large birds. They often

 is found in the fossil state at Lyme Regis.

 Animal, the arms with four rows of cups or suckers : the
