of Seminula sp. (cf. ficotdea), nearly all of which have the two valves 
adherent. Many of the specimens, however, are much crushed and 
broken. Occasional examples of single valves may be found which 
exhibit their Athyrid characters remarkably well. On the weathered 
faces of this bed, very definite lines of stratification may be observed, 
alternating between the layers of shells. The only other species, 
so far, noticed in this band is a small fragment of an Athyris showing 
concentric lamellation. There is a possibility of some of the others 
being Athyris also, which have lost their outer layer and therefore 
resemble Seminula. In its general appearance this band bears 
a striking resemblance to a modern sea-beach, where shells are thrown 
up in hundreds ; and it may, in all probability, represent an old shore- 
line. The same form of Semznula also occurs scattered through the 
beds below the above-mentioned band. 
At the top of the Fell, at the Meathop Fell end, I obtained the 
following species: Spor ifer cf. furcatus, M‘Coy* (abundant), Reticularva 
aff. lineata (Martin) (rare), and one or two others too imperfect to 
identify with safety. Other species collected at various parts of the 
Fell are, Psammodus rugosus, Ag. (fragment of tooth), Huomphalus sp. 
(cast), Lenestella sp., Seminula (2? ambigua), and Produetus aff. cor- 
rugatus, M‘Coy. 
The plant bed is apparently not exposed at the southern end of the 
Fell, as I have never seen any traces of it here. Where it does crop 
out is some little distance to the north. Associated with the plant 
remains are some small Seminulas and a Syringopora of a small 
ramulose type, which does not appear to have received a name yet. 
In beds immediately above, masses of Syringopora occur in abundance, 
and where these beds crop out at the surface large specimens may be 
obtained beautifully weathered out and free from matrix. With 
regard to the species of Syringopora, Dr. Sibly, to whom I submitted 
specimens, has .no hesitation in calling it a small variety of 
S. geniculata, using that name merely as a group name, and adopting 
Edwards & ,Haime’s interpretation of the name. He says it is 
distinctly smaller than the S. ef. genteulata which abounds in D, of 
the South-West and the Midlands, but is of the same type. | 
It is perhaps premature to attempt to fix definitely the exact horizon 
of these beds, as they appear to have been, as yet, but superficially 
studied. 
As already mentioned in the North Wales exposure, 4. Vanucemi 
occurs in beds which are assigned to the S, subzone. In the Shap 
exposure, the exact horizon ‘and fossil associates of A. Vanuxemi 
are, unfortunately, not so well known. My friend Canon Crewdson, 
honorar y. curator of the Kendal Museum, tells me that the Shap 
Yoll-bar quarry (now closed), from which their specimens came,. is 
about 13 miles south of the village, He has since found the species. 
in an old quarry at the northern end of the village, but cannot 
remember seeing any other fossils associated with it. In his opinion 
the ‘ Vanuxemi Bed’ forms part of the Shap—Ravenstonedale Limestone, 
probably near the top. He has, however, seen no trace of 4. Vanuwemt 
1 This and several others were kindly identified by Dr. T. F. Sibly, F.G.S.
