 The Tertiaries of the environs of Montpellier, &c. consist at the base 

 of Eocene lacustrine and terrestrial beds, with Bulimus subcylindricus, 

 Flahellaria gelyensis, &c. ; closely connected with these follow lignites, 

 with Melanopsis Mausiana and Palceotherium. Above are found Oli- 

 gocene lacustrine beds, conglomerates, grits, red and yellow clays, 

 300-400 metres thick. Next come the blue marine marls of the L. Mi- 

 ocene (Aquitanian), and lastly Pliocene. E. B. T.
