2300 and 2 740 fathoms, and of the remainder only three have a depth of less than 
1300 fathoms.

This pretty variety is described by its authors in the following terms : — “ Test decanter- 
shaped, neck long and coiled ; body gradually widening and smooth to the base, which 
for half its radius is widely and deeply crenate with broad radiating furrows ; the centre 
of the base being smooth and gently convex.” Length, about ^th inch (0‘5 mm.). 
Lagena crenata is a somewhat rare form, and though it has been found in a consider- 
able number of localities it is nowhere abundant. The distribution-list includes several 
points in the British seas, at depths of less than 60 fathoms ; the North Atlantic, west of 
Ireland, 183 fathoms; the Cape of Good Hope, 15 to 20 fathoms; Australian shore- 
sands; off East Moncceur Island, Bass Strait, 38 fathoms; and three Stations, in deep 
water in the South Pacific, 2325 to 2425 fathoms. 
It occurs as a fossil in the Middle Tertiaries of Bordeaux and Malaga (Parker and 
Jones), and in the Post-tertiary deposits of Southern Italy (Seguenza).

Test subglobular or pyriform, rounded or compressed, entosolenian ; surface orna- 
ment consisting of excavated furrows radiating from the centre of the inferior end ; radii 
fluted, broad and rounded at their anterior margins, sometimes bordered, extending 
nearly to the middle of the test. Length, ^th inch (0”42 mm.), more or less. 
A somewhat rare variety, in which partial sculptured ornament takes the place of the 
usual exogenous thickening. 
But few specimens of Lagena exsculpta have been met with, and these are from 
localities far apart, namely : — one Station in the North Pacific, depth 2300 fathoms ; two 
in the South Pacific, 800 fathoms and 1100 fathoms respectively; south of Australia, 
2600 fathoms ; the Antarctic Ice-barrier, 1300 fathoms ; and one point in the South 
Atlantic, 1425 fathoms. Terquem records a similar form from the French coast. 
A shell with almost identical characters, Lagena florida, is figured by the same
