THE CARBONIFEROUS LIMESTONE OF SOUTH-WEST GOWER 5B 
Note on the brachiopods and corals, collected by Dr. 
Brendon Gubbin, from the carboniferous lime- 
stone of SOUTH-WEST GOWER, and the zones which 
they indicate. 
By Arthur Vaughan, b.a., d.sc., f.g.s. 
I N the following faunal lists the relative position of the 
fossils and their association are stated on Dr. Gubbin’s 
authority, checked by the rough test of similarity or dis- 
similarity of matrix. 
Explanations of the Zonal terms and symbols, as well as 
notes on the denotation of the fossil names, are given in my 
paper on the “ Palaeontological Sequence in the Carboni- 
ferous Limestone of the Bristol Area ” (Q.J.G.8. vol. Ixi.). 
CLEISTOPORA ZONE, AND K^. 
Fully developed near Parkmill. 
Fauna. — The number of specimens is small. Spiriferina 
octoplicata is apparently not uncommon in the upper part 
of the zone, where it is associated with an early fauna. 
Eumetria cf. carhonaria, and Modiola lata occur (in 
association with Camamtmchia mitcheldeanensis) near the 
base of the zone ; the fact that these two forms have only 
been found elsewhere in the lowest beds of the Car- 
boniferous Limestone, where that formation lies conform- 
ably upon the Upper Old Red Sandstone, would suggest 
the same conformity in the Gower Peninsula.
