the shell, and is central and free ; in these respects differing from 

 the Other compressed Lagense in which, as a rule, the entosulenian 

 tube is attached throughout its whole length to the internal surface

of one of the faces of the test. The trifacial form L. tngono-ornata 

 Brady is represented by a few feeble examples. 



Living, the species is widely distributed. Fossil, it has been 

 recorded from the Miocene deposits of Sicily ; from the Pleistocene of 

 Canada ; from the Coralline Crag : and from the Tertiary beds of 

 St. Erth.

 plentiful in Area 2.

This species seems to differ from L. lagenoides only in the raised 

 border which immediately surrounds the body of the test. As in 

 L. lagenoides, the form varies considerably. 1 n the example repre- 

 sented by fig. 11 the raised border is composed of beads instead of 

 the usual punctate ornament. 



It is rare in the Malay Archipelago, although found in both Areas.
