the place formerly occupied by the seed, and the interior of the cavity of the fruit is 
then partly filled with it. 
Ludwig {l.c.) has united these fruits with Hipjpopha'e, adopting, without necessity, a 
new specific name. These fruits do not, however, agree in the least with those of 
po^phae, and decidedly cannot be referred to that genus. He believes that great numbers 
of such fruits were arranged close together upon the boughs, which circumstance pro- 
bably led him to refer them to HippopJia'e. But it seems to me doubtful whether those 
little heaps of fruits which he represented were really fixed on the houghs that lie close 
by, or whether they lie only accidentally near the boughs. If they are fixed on the 
boughs, it will be proved that they are phanerogamic fruits and not seeds, while the 
interpretation as Hippophae is not justified, considering the other contradictory marks. 
The C. Wehsteri has been described so firequently and so carefully, that any more 
detailed description would be superfluous. I refer the reader especially to the very exact 
description of Hookee (/. c.). Investigation with the microscope showed me that the 
sac in the interior of the fruit is formed by cells with very thin walls and of different 
lengths (cf. fig. 6 d, c), as represented by Hookee ia fig. 7, and that the pericarpium, 
on the contrary, is formed by ligneous cells, which partly show a very curious undulating 
circumscription, and are dotted (fig. 6). They are arranged in series*. 
45. Caepolithes scutellatus, m. (Plate LXIX. fig. 30, magnified 30 b.) 
C. fructibus complanatis, margme acutis, rotundatis, basi truncatis, dorso costulatis. 
A few specimens in the 26th bed at Bovey. 
It is a perfectly flat fruit (or seedl) with an acute margin (cf. the section of fig. c) ; at 
the base it is truncated, at the sides much rounded, obtusely rounded above, nearly in 
the middle somewhat emarginate. From the base originate a few delicate, partly ramified 
ribs, which reach somewhat above the middle. 
It is rather like the fruits of Panax^ but the middle partition is wanting. 
Since I had only one well-preserved fragment at my disposal, I could not cut it open in 
order to see whether it had one or two furrows. Perhaps it may be a seed, and not a fruit. 
46. Caepolithes Bovetanus, m. (Plate LXX. figs. 7-14.) 
C. nucula 3-4^ mm. longa, ovata, apice mucronulata, dorso leviter sulcata, mono- 
sperma. 
Frequent in the 26th bed at Bovey. 
* The drawing M. A. Beoxgxiaet has given of this species is very imperfect. I did not myself recognize 
his drawing as belonging to this species ; but Dr. Eaxconee convinced me that it was so. I compared, in 
the British Museum, the Carpolithes thalictr aides, var. Wehsteri, Brongn., of the Isle of Wight with the fruit 
from Bovey and Kaltennordheim, and am assured that they form one species. But the Ca/rpolithes tTialic~ 
troides, Brongn., must be separated from Carpolithes Wehsteri, as the fruit of the former species is cylindrical 
and acuminated, whilst the fruit of O. Wehsteri is obtusely rounded. Unhappily the place where these speci- 
mens of the Isle of Wight were found is not mentioned in the British Museum. The stone is dark, and different 
from the White Clay of Alum Bay, where plants are lying. Perhaps they are from the Bembridge series. 
Latterly I have received many seeds of this species from the Hempstead beds of the Isle of Wight.
