Heophax Montfort [ 1808 ]. 
Reophax lageniformis, plate V. figs. 1 a and b. 
This form consists of a compressed flask-shaped chamber, the test 
of which is composed of fine sandy material of a brick-red or brown 
colour. The mouth is produced slightly beyond the circular contour 
of the shell, and is devoid of the colour present in the rest of it. 
Length 1 /60 in. This variety differs from R. diflugiformis in the 
compressed and non-elongate form of the shell, and from R. ampul- 
lacea in the latter characteristic, and also in the fine texture of the 
shell. A form somewhat resembling this is figured by M. Berthelin 
from the Gault of Montcley,f but the test is very coarsely arenaceous, 
whilst those of the Folkestone specimens are fine and smooth. It 
occurs in zone xi., at 35 ft. from the top, one specimen ; and 6 ft., one 
specimen.
