REPORT ON THE FORAMIN1FERA. 
46.' 3 
tlie body of the test having an additional surface-ornament of longitudinal strife or 
costae. Length, -h^th inch (0'36 mm.). 
This form is allied to the Lagena alifera of Reuss, but the wings are only four in 
number and conspicuously tubulated, and the intermediate portions of the test are striate 
or costate. 
Lagena quadralata is a rare deep-water variety, only found hitherto at two localities, 
namely : — Station 160, south of Australia, 2600 fathoms ; and Station 332, South Atlantic, 
mid-ocean, 2200 fathoms.

Test flask-shaped, with long, slender, ectosolenian neck ; surface-ornament consisting 
of ten or twelve longitudinal costae, the inferior portions of which are developed into wide, 
feather-like, tubulated wings. Length, ^th inch (0’63 mm.). 
An exuberant deep-water modification of Lagena sulcata, the best specimens of 
which have been obtained from the tropical regions of the South Pacific, at depths of 2425 
fathoms and 2350 fathoms, and less characteristic examples from near the Cape de Verde 
Islands, 1070 fathoms.

Lagena semistriata is the name applied to a group of intermediate forms presenting 
considerable diversity of contour, but characterised by the partial nature of the surface- 
ornament, which consists of costae, springing from the base of the shell but terminating, 
often abruptly, before reaching the middle.
