The test of Lagena globosa is subgiobular, pyriform, or elliptical, and the aperture is 
situated in an entosolenian neck. The wonderfully diversified characters of the external 
orifice have already been adverted to (ante, p. 441). The surface of the shell is invariably 
smooth. 
In the living condition Lagena globosa is a cosmopolitan species, frequenting every 
latitude and almost every depth of water at which calcareous Foraminifera have been 
found. 
Whether its geological distribution extends to older horizons than the Oolite cannot 
lie stated with certainty. Specimens similar in general contour, but more or less 
rugose externally, have been met with in Carboniferous Limestone shales, and 
these, pending further research, have been assigned to Lagena aspera ; but from the 
•Jurassic age to the Post-tertiary, the typical form is a constituent of almost every marine 
fossiliferous deposit.

Lagena apiculata is an entosolenian variety, only differing from Lagena globosa 
in having a pointed instead of a rounded base. 
Like the allied form it is cosmopolitan, and has been found at every depth from the 
littoral zone down to 2750 fathoms. 
It is also one of the commonest of fossil Lagence, occurring in microzoic rocks of 
almost every age as far back as the Lias.
