This beautiful variety belongs to the wide-flanged type of 

 L. marginata. On the lateral aspect the test is decorated with 

 two or more chain-like borders encircling the bulbous portion. A 

 remarkable feature about this variety is its apiculate base, encom- 

 passed, however, within the thin outer flange. The oral extremity 

 of the test is distinctly phialine or lipped, partially closed over with 

 redundant shell-growth, and showing a secondary tubular (true) 

 orifice within. The outer flange is mined by a microscopic boring 

 plant. Length of test -^ inch (1-47 mm.). 



One example found in Sample No. 6, very rare.
