LAGENIDA. 39 



mosa. Many specimens show their connection with the former in having stout longi- 

 tudinal ridges, with very slightly developed cross-bars ; whilst others, with equally grown 

 ornament, only want a zigzag inflection of the primary costse to give them the characters 

 of L. squamosa. We have suggested an artificial division of these closely allied Lagena 

 into — 1, those with square meshes (Z. Melo) ; 2, those with six-sided meshes (Z. hexagona. 

 Will. L. favosa, Reuss) ; and 3, those with both four- and six-sided meshes (Z. squamosa, 

 Mont.). The last two groups may be conveniently treated of together, as below. Lagena 

 Melo is not uncommon in company with other members of the group, though not so 

 frequent as the smooth, sulcate, honeycombed, and marginate varieties ; and it has the 

 same world-wide distribution ; it is found fossil also in many Tertiary beds. For its 

 occurrence (recent and fossil) in the Mediterranean area, see ' Quart. Journ. Geol. Soc.,' 

 vol. xvi, Table, p. 302. 



In the Crag it appears confined to the bed at Gedgrave, containing Cardita senilis ; 

 and the specimens are rare.
