gravels on geological rather than on palaBontological evidence, the 
accompany iuj^ list of Farringdon Brachiopoda, from specimens which 
1 have myself collected, may not be uninteresting. I regret that I 
cannot add a list of the small Bryozoa. etc., as several of the species 
are common alike to the Lower Greensand pebble-beds of Godalming 
and the Sponge-gravels. 
In this Table, the columns 1, 2, 3 show the species of Brachio- 
poda met with by Mr. Evans and myself in our visit to the spouge- 
gravel pits. Col. 4, 5, 6, I have added, as showing instances of the 
occurrence of the same species in the Lower Grreensand of Godal- 
ming and Shanklin, which have come under my own observation; and 
col. 7, as showing their recorded occurrence in British Cretaceous de- 
posits of an age younger than that of the Lower Greensand. The 
absence in the Farringdon deposits of such Upper Greensand forms 
as TerehrateUa pectita, Terehratulina striata, Kingena lima, T. ovata, 
T. hiplicata, T. obtusa, Ehynchonella compressa, M. sulcata, and R. gra- 
siana, species which do not appear to be uncommon at Warminster 
and Cambridge, has long seemed to me to be a fi\ct of much signifi- 
cance.

Eozier says, in his ' Journal de Physique,' 1782, page 171, that 
"mention is made in the Catalogue of Daviia of a tibia and of a beak 
imprinted on two different stones." If there be any other notice in 
Daviia than the passages we have quoted, it has escaped our search. 
In 1782, M. Kobert de Paul de Lamanon gave, in the Abbe 
Eozier's ' Journal de Physique' (vol. xx. p. 171), an excellent sum- 
mary of what was then known of Ornithic fossils. After noticing 
the accounts in Albertus ^Nlagnusand other old authors, he goes onto 
say in his ' Description de Divers Fossiles trouves dans les carrieres 
de Montmartre, pres Paris, et vues geiierales sur la formation des 
Pierres gypseuses,'* " M. Kouelle, according to M. Darcet, found iu 
the plaster quarries of JNlontraartre parts of a bird separated one 
from the other, 1 (Lamanon) have seen also in the Cabinet of Natu- 
ral History of Bordeaux, some bones that it has been attempted to 
refer to birds; they were found by the AbbeDesbiey in the quarries 
of Leognan, which are at two leagues from this capital. AVe can 
only assert, however, that these isolated bones may have belonged to 
birds, on the ground that their medullar}' cavity is very large rela- 
tively to their thickness. No anatomist has determined what is the 
relation of this cavity to the osseous portion iu the different classes of 
animals ; it is even probable one could not establish any general rule
