 Riz. Retic. nella Mama Plioc. del Ponticello di Savena, 

 Bologna, fig. 16. 



PI. 16, fig. 21. This is rather a stoutly-built form. The aperture 

 is fissurine and the test apiculate. Locality : Nos. 22, 24. 

 Rather rare. 



There are a few very small examples that appear to be almost 

 identical with Fornasini's figure. Locality : Uncertain. 



+ PI. 17, fig. 30. Only two or three found. Locality: Nos. 

 42, 44, and two or three examples at one or two other stations.

Lagena marginata Walker and Boys var.

Lagena marginata Walker and Boys var. catenulosa Chapman

Lagena marginata Walker and Boys var. catenulosa (Chapman) 



Sidebottom, 1912, Journ. Q. M. C, p. 407, pi. 18, fig. 6. 



PI. 16, fig. 22. Four examples occur. The one chosen for 

 illustration hardly shows a trace of the chain-pattern, and the 

 test is free from exogenous shell-growth. The others show the 

 chain-pattern. One of the specimens has the body of the test 

 covered with exogenous beads. The few tubuli shown in the 

 drawing are caused, I believe, by the borings of some animal. 

 Locality : Nos. 1, 5, 10.
