 quiet and unassuming manner a remarkably sympathetic dis- 

 position. He died on the 9th of March, 1908. 



Charles Louis Perceval de Loriol-Le Fort (1828-1908). — 

 Perceval de Loriol was born in Geneva in 1828. Destined by his 

 father for agricultural pursuits, he began life as a farmer soon 

 after leaving school, where he had received a classical education. 

 An irresistible inclination towards natural science soon led him to 

 abandon this career, and he returned to Geneva to pursue the 

 study of zoology, and palaeontology in particular. His teacher, 

 P. J. Pictet de la Rive, was an ardent student of the Mesozoic 

 faunas of Switzerland and published, in collaboration with his 

 pupils, the well-known ' Materiaux pour la Paleontologie de la 

 Suisse'. The first fruits of.De Loriol's work was a joint memoir 

 with De la Rive on the fossils of the Keocomian limestones of the 

 Yoirons, which appeared in 1858. From that time to the end of 

 his life the palaeontology of Switzerland was the one object of his 

 study, memoir after memoir flowed from his pen, and the proof-sheets 

 of the last that he was ever to write was given to the editor of 

 the 'Revue Suisse de Zoologie' but a few days before his death. 

 We owe the fouadations of all exact stratigraphical knowledge of 

 the Upper Jurassic in Switzerland to his careful specific descriptions. 

 The Jurassic, Cretaceous, and Tertiary echinoderms of Switzerland 

 were very completely investigated by De Loriol, and are described 

 in his ' Echinologie helvetique,' published in two large volumes, 

 between the years 1872 and 1875. He also wrote the volume of 

 the ' Paleontologie francaise,' treating of the Jurassic Crinoids, and 

 a monograph of the Tertiary Echinoids of Egypt, and described the 

 echinoderms of the Secondary and Tertiary rocks of Portugal. 

 ■ r , De Loriol founded the Societe Paleontologique Suisse ; he was 

 the perpetual editor of its publications, and administered almost 

 all its affairs. 



He was elected a Foreign Correspondent of our Society in 

 1894, and he died on December 23rd, 1908, in the 81st year of 

 his age. 



De Loriol restricted his attention with unwavering devotion 

 to systematic palaeontology ; in this field he was an exact and 

 conscientious observer ; outside it his interests were limited, he cared 

 little for theories of development, the building-up of genealogical
