gravels on geological rather than on palseontological evidence, the 

 accompanying list of Farringdon Brachiopoda, from specimens which 

 I have myself collected, may not be uninteresting. 1 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 sponge- 

 gravel pits. Col. 4, 5, 6, I have added, as showing instances of the 

 occurrence of the same species in the Lower Greensand of Godal- 

 ming and Shanklm, 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 Tercbratella pectita, Terebratulina striata, Kingena lima, T. ovata, 

 T. biplicata, T. obtusa, Bhynchonella compressa, JR. sulcata, and B. gra- 

 siana, species which do not appear to be uncommon at Warminster 

 and Cambridge, has long seemed to me to be a fact of much signifi- 

 cance.

Bozier says, in his 'Journal de Physique,' 1782, page 174, that 

 " mention is made in the Catalogue of JJaviia of a tibia and of a beak 

 imprinted on two different stones." If there be any other notice in 

 Davila than the passages we have quoted, it has escaped our search. 



In 1782, M. Kobert de Paul de La man on gave, in the Abbe 

 Rozier's ' Journal de Physique' (vol. xx. p. 174), an excellent sum- 

 mary of what was then known of Ornithic fossils. After noticing 

 the accounts in Albertus Magnus and other old authors, he goes onto 

 say in his '.Description de Divers Possiles trouves dans les carrieres 

 de Montrnartre, pres Paris, et vues generales sur la formation des 

 Pierres gypseuses,'* " M. liouelle, according to M. Darcet, found in 

 the plaster quarries of Montrnartre parts of a bird separated one 

 from the other. I (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 Abbe Desbiey in the quarries 

 of Leognan, which are at two leagues from this capital. We can 

 only assert, however, that these isolated bones may have belonged to 

 birds, on the ground that their medullary cavity is very large rela- 

 tively to their thickness. No anatomist has determined what is the 

 relation of this cavity to the osseous portion in the different classes of 

 animals; it is even probable one could not establish any general rule
