4 86 BERGONIA.
GENUS 147. BERGONIA TEMPERE, 1891.
Fig. 221. Bergonia Barbadcnsis.
Valve almost circular, slightly con-
vex, with cellular structure, interrupted
by two large hyaline spaces, subreni-
form, opposite one another, and
inclined to one another at an angle of
40. Each hyaline area encloses at
its median and dorsal portions a small
oblong ocellus, whence arise two
silicious inflations, running in a
direction towards the apices of the
hyaline Spaces.
This genus only comprises one species, Bergonia Barbadensfs Temp. (fig.
221), from the Barbadoes deposits. My figure is drawn from a photograph
which I made from a valve Mr. Tempere was good enough to entrust to me.
