‘VOL. XV. (2) C. UPTON—BRACHIOPODA gI 
Many of the small cavities occurring in the Coral bed 
which lies upon the Pea-Grit at the Frith are filled in with 
a yellow marly material, in places quite soft, and contain- 
ing immense numbers of minute fossils. Amongst the 
micro-brachiopods there are a great number of specimens 
of the above three forms, together with many others, 
several of which appear to be as yet undescribed. 
The three species of brachiopods referred to were 
described by the late Charles Moore from specimens 
found at Dundry, where they appear to be not uncommon, 
but hitherto they have not been recorded from the 
Cotteswolds. 
Dr Davidson’s figures are copied from the original 
illustrations in the Proceedings of the Somersetshire 
Archeological and Natural History Society. In the case 
of the Zhec. eranulosum, the supramembraneal disc is 
shown to be imperforate, but judging from my own speci- 
mens I should imagine that this is due to a deposit of 
calcareous matter in the process of fossilization, and that 
during the lifetime of the organism the disc did not con- 
sist of a continuous layer of shell. In my own specimens 
in all cases in which the disc is retained it is perforated 
somewhat after the fashion of a calcareous sponge. 
Crania Saundersiz, as figured in the monograph, would . 
appear to be drawn from immature specimens, as my own 
examples—assuming that my identification is correct—go 
to show that at maturity the shells become imbricated. 
_ Speaking generally, the Cotteswold specimens of these 
small shells appear to be better preserved and wash out 
more cleanly than the Dundry specimens. 
NOTE.—Since the paper was read I have seen Mr 
Moore’s paper in the Geologist for 1861, and I 
find that he states on p. 98 that Cranza Saundersit 
occurs in the Inferior Oolite of Minchinhampton. 
The record is therefore not new.
