Small Adiantoid pinnae had been met with among the interlaced fronds and stems of 

 Gleichetiia at Bournemouth (see p. 44), to which we considered they might have belonged, 

 but, as similar pinnae have since been found unassociated with Gleichenia and preserving 

 distinct remains of sori, there is no longer any doubt that a species of Maidenhair, not 

 much larger than Adiantum capUlus-Veneris, formed part of our Middle-Eocene flora. 

 As we see no reason to consider them distinct specifically from those found by Count 

 Saporta at Sezanne, which only seem to differ in the absence of sori, we have placed 

 them, with his concurrence, in that species. The segments seem to be dimidiate, as the 

 line of fruit is only present on one side. This species difl'ers strikingly from the group 

 of A. capillus- Veneris in the linear, instead of obversely reniform, arrangement of the 

 sori. 



Detached segments are occasionally met with among dicotyledonous leaves in beds 

 west of Bournemouth Pier.

Middle Bagshot, Bournemouth. 



The palmate form, rectangular base, and long stipes show the specimen figured 

 (PI. XI, fig. 1) to have been an entire frond, and not a large terminal pinna. So much 

 of the frond is preserved that little is left to the imagination in restoring it. It was 

 nearly equal-sided, palmate, somewhat irregular in form, bluntly six-lobed more than 

 half-way down, each lobe being again once subdivided. It measured six inches
