VINE : PALAEONTOLOGY OF THE WENLOCK SHALES.

Nos. 38 and 40. These washings, Mr. Maw says, are the same, and 
the shales were obtained from exposures near the base of the 
"Wenlock shale, on the banks of the river Severn, above 
Buildwas Bridge. 
No. 36 is also from the base of the Wenlock shale, but from the 
middle of the exposure. 
No. 37. "Washing from Buildwas beds, near the base of Wenlock 
shale, north end of exposure, side of river Severn, above 
Buildwas Bridge, Shropshire." G. Maw. 
No. 22. Washing from the base of the fossiliferous zone of Build- 
was beds, Harley, near Wenlock. 
Above these various zones at Benthal Edge, the Wenlock lime- 
stone. No. 7, of Mr. Davidson's divisions, "dips from 15° to 20° 
S.S.W.; to the westward the dip decreases from 10° to 15°, and at 
the eastern extremity of the escarpment of Lincoln Hill, near Coal- 
brook Dale, the inclination increases to from 45° to 50° 
From careful measurements made on Benthal Edge it has been ascer- 
tained that the compact limestone is from 80 to 90 feet in thickness, 
and it thickens somewhat in the direction of Wenlock to the south- 
west." * 
Overlying the Wenlock limestone there are some soft shales, 
about 100 feet in thickness, and these are exposed in cuttings by the 
side of the railway between Buildwas and Wenlock. The material 
represented by No. 24 was contained in a very small package, and it 
is by no means remarkably characteristic. 
No. 46 are washings from shales over the Wenlock limestone, and 
were obtained from the railway cutting between Wenlock and 
Buildwas. It is singularly rich in small corals, Entomos- 
traca and the fry of Brachiopoda, many of which are similar 
to species found in the Wenlock limestone. 
In my list of species I have endeavoured to represent, fairly as 
well as comparatively, the fauna of the different washings, and it will 
be possible for the palseontological student, with the list before him, 
to make comparisons of the fauna of the Shropshire shales, with the 
fauna of other Wenlock horizons, British as well as foreign.
