VI.—On rue Discovery or ArcwmosregiLLARiA VAnuxemt (GOPPERT) 
at Mratnor Frnt, WEsTMorLAND, wiTa A Description OF THE 
Locatiry. 
By J. Witrrip Jackson, F.G.S., Assistant Keeper of the Manchester Museum. 
N September last I discovered a number of plant remains in the 
| Carboniferous Limestone at Meathop Fell, Westmorland, amongst 
which were several fragments of what, at first sight, looked like 
a species of Lepidodendron. A closer examination, however, of one or 
two of the better preserved specimens, which showed traces of leaf- 
sears, at once suggested Archeosigillaria Vanuxemi, specimens of which 
I had previously seen in the Kendal Museum. 
On a later visit to Meathop Fell I was successful in obtaining 
a number of other fragmentary specimens of the same plant, along 
with a specimen of a cone, which from its position and association 
with branches of 4. Vanuxemi, has every appearance of belonging to 
that species. Unfortunately the branch beari ing it is so badly preserved 
that no definite details can be made out, ene there is no conclusive 
proof that it belongs to the above species. ‘his is all the more 
unfortunate, as, up to the present, the fructification of this interesting 
plant is unknown. 
The majority of the plant-remains found appear to be referable to 
‘the above species, but one or two specimens occurred which looked 
like the flattened stems of other plants. The identification of these, 
however, is impossible, owing to their badly preserved condition. 
I also cbtained a portion of the stem of Bothrodendron sp., which will 
be referred to later. 
The present discovery of A. Vanuxemi constitutes the third 
recorded occurrence of the species in Britain. The first British 
specimens, which are in the Kendal Museum, were brought to the 
notice of Dr. Kidston by Mr. R. Bullen Newton, F.G.S., and were 
described in 1885 as Lycopodites (Sigillaria) Vanuxemi.! These 
specimens were collected from the lower beds of the Mountain 
Limestone, near Shap Toll-bar, Westmorland. In 1899 Dr. Kidston 
created the new genus, Archaosigillaria, for the reception of this plant.” 
The second discovery was made near Dyserth, North Wales, by 
Dr. Wheelton Hind, F.R.C.S., etc., and Mr. J. T. Stobbs, F.G.S.* 
Here the species was fairly common, and was associated with a fauna 
characteristic of So. 
It may be of interest here to call attention to the fact that the type 
of the species was discovered in the Upper Devonian (Chemung Group) 
of New York, but all the British examples originate from a higher 
horizon.*

Archeosigillaria Vanuxemi (Goppert). 
The largest specimen I obtained measures 18cm. in length, the width of the 
branches being from 8 to. 10 mm._ It exhibits very clearly the dichotomous branching 
of the species, but owing to the branches being flattened by pressure and rather badly
