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 cost to give them the characters 
of LZ. sqguamosa. We have suggested an artificial division of these closely allied Lagene 
into—l1, those with square meshes (ZL. JZe/o) ; 2, those with six-sided meshes (L. hewagona, 
Will. JZ. favosa, Reuss) ; and 3, those with both four- and six-sided meshes (ZL. squamosa, 
Mont.). The last two groups may be conveniently treated of together, as below. Lagena 
Me/o 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.
