DE. HEEE ON THE FOSSIL FLOEA OF BOYEY TEACET. 
Belongs probably to Anona altenburgensis, Ung. (Sylloge Plantar, p. 26, pi. 10. figs. 
8-11). The representation agrees pretty well with the seeds of Bovey; but as Uxgee 
in the diagnosis calls the seeds “ ovato-oblongis,” and since those of Bovey are no wider 
at the base than at the top, I dare not to unite them with those of Altenbm'g. 
Most of the specimens are 20 to 21 millims. long, widest in the middle, narrowing 
symmetrically towards both ends, where they are most obtusely rounded. They are 
flat, the diameter only amounting to millims. ; throughout they are formed of an 
homogeneous mass of coal, which has obliterated all traces of the contents of the seeds. 
On the outside they are smooth and rather shining when rubbed; sometimes they 
appear reticulated by delicate fissures, or furrowed with very fine longitudinal and trans- 
verse striae, which are, however, much obliterated, and can only be perceived by the 
aid of a lens. In some pieces the middle portion is perfectly flat and slopes towards a 
rather sharp margin (cf. section, fig. 2 h\ thus forming a flatly bordered seed like those 
of A. ^akodosa, Ait. ; in others the margin is blunted. In one piece (fig. 3) the middle 
portion has fallen out, thus producing a broad and deep furrow ; this is probably only 
accidental. 
In fig. 1 the seed still lies within the stone, convincing us that it is not surrounded by 
a shell. The perfectly homogeneous substance of the coal indicates a seed and not a 
fi’uit; and since the Anonas (especially the A.paludosa Asimina triloha) have quite 
similar seeds, I agree with the determination of Unger, although it cannot be denied 
that it must be considered as somewhat doubtful till other organs shall be discovered. 
37. Anona cyclosperma, m. (Plate LXX. fig. 4.) 
A. seminibus suborbiculatis, 14 mm. longis, 11-12 mm. latis, compressis, rugulosis. 
At the same spot ; several specimens. 
They are very like the preceding, but "much smaller, especially much shorter ; and as 
the breadth is nearly the same, they are almost orbicular ; a network is constituted by 
numerous ii’regular fissures, which cause the outside to be somewhat wrinkled (fig. 4 h). 
Since no intermediate forms occur between this and the foregoing, they seem to belong 
to difierent species. 
Order III. HYDEOPELTIDE^. 
Earn. Nympho ACE uE, Salisb. 
I. Nymph^a, Linn. 
38. Nymph^a Doris, m. (Plate LXX. figs. 32-37.) 
N. seminibus ovalibus, 2^3^ mm. longis, subtilissime crenulato-striolatis, apice poro 
perforatis. 
From the 54th bed. 
* 
Tolerably numerous flattened seeds lying close together : they are oval, 2^ to 3^ millims.
