In the uppermost part of the upper Triassic series two bone-beds are known, one 
of which is found at Mt Bertil and Mt Lundbohm at a height of 350 m above the fish 
horizon, the other only at Mt Bertil about 263 m above the fish horizon. The former 
of them was mentioned by Wiman in 1914 in connection with his description of the 
Stegocephalians (1914 b, p. 8) 
Profiles. — I publish here some of the profiles that have been measured during 
the expeditions of recent years, but must preface them with the remark that the 
statements as to the thicknesses cannot lay claim to any very great degree of accuracy, 
as all the measurements are made with ordinary aneroid barometers.
