one part with well-preserved plant-remains. The end of this band 
exposed in the cliff has been worked on several occasions, and 
Mr. Prestwich, Dr. Bowerbank, and two or three museums have 
obtained collections of the leaves. A list of the plants found has 
been given in No. 42 of the Geological Survey Memoirs. This list 
must not, however, be looked upon as complete, for further working 
brings to light many new forms. The author has had a collection 
made by Mr. Henry Keeping, the well-known geological collector, 
and he obtained some 350 leaf- and 50 fruit-remains. Some of these 
have not been recorded before. 
In the collection is a Ficus, somewhat like F. Bowerbankit (De la 
Harpe), but with the angles of venation much greater, and it can 
hardly be referred to that species. The author also described a 
Juglans with serrated edge, which was certainly not Juglans Sharpet 
(De la Harpe). 
There are two or three specimens of a large trilobed Acer, and a 
Cinnamomum, very like C. Scheuchzeri, from Bovey Tracey [Pen- 
gelly, Bovey Tracey, Pl. XVI. fig. 12], and a leguminous leaf, pro- 
ably a Podogonium. Many other fragments were found, which could 
not be referred to recorded species, but were too imperfect to be 
described as new forms. A cone had also been obtained, about which, 
however, the writer would not venture an opinion. But the most 
interesting discovery was that of two flower-remains, which appear 
to resemble Porana Giningensis [| Heer, Flora Tert. Helv. Pl. XVI. 
fig. 12.]. Adrawing of the two is given for comparison.

‘The part preserved in the P. Giningensis must be the calyx, as 
the corolla is monopetalous. Sut for the finding of these solitary 
flower-remains in the Swiss Tertiaries, one would have been dis- 
posed to consider the Alum Bay specimens to belong to a polype- 
talous [pentapetalous] order; and the small elevations around the 
central dise might be viewed as the remains of stamens. ‘The writer 
accepts provisionally the view of their belonging tothe genus Porana, 
giving them the specific name Vectensis, in consideration of the points 
in which they differ from P. Giningensis. 
The list, however, of the remains preserved in this bed is not to 
be completed without further working, in aid of which the British 
Asoociation have already made the author a grant,
