esting fauna. His later publications en extinct Amphibians 

 and Reptiles were also noteworthy. Jager's investigations on 

 the extinct vertebrate fauna of Wurtemberg, published between 

 1824 and 1839, were an important advance. To Plieninger's 

 researches in the same region, 1834-44, we owe the discovery 

 of the first Triassic mammal (Microlestes), as well as important 

 information in regard to Labyrinthodonts. Kaup's researches 

 on fossil mammals, 1832-41, brought to light many interesting- 

 forms, and to him we are indebted for the generic name 

 Dinotherium, and excellent descriptions of the remains then 

 known. 



Count Minister's "JBeitrage sur Petrifacten^Kwnde" pub- 

 lished 1843-46, contained several valuable papers on fossil 

 vertebrates ; and the separate papers by the same author are of 

 interest. Andreas Wagner wrote on Pterosaurians in 1837, 

 and later gave the first description of fossil mammals of the 

 Tertiary of Greece, 1837-40. Johannes Midler pubhshed an 

 important illustrated work on the Zeuglodonts, in 1849, and 

 various notable memoirs ; and Quenstedt, interesting descrip- 

 tions of fossil reptiles, as well as other papers of value. Eiiti- 

 meyer's suggestive memoirs are widely known. 



Hermann von Meyer's contributions to vertebrate palaeon- 

 tology are by far the most important published in Germany 

 during the period we are now considering. From 1830, his 

 investigations on this subject were continuous for nearly forty 

 years, and his various publications are all of value. His 

 "Beitrage sttr Petrifacteiikunde" 1831-33, contains a series of 

 valuable memoirs. His "Palceologica," issued in 1832, includes 

 a synopsis of the fossil vertebrates then known, with much 

 original matter. His great work, " Zur Fatma der Vorwelt" 

 1845-60, includes a series of monographs invaluable to the 

 student of vertebrate palaeontology. This work, as well as his 

 other chief publications, was illustrated with admirable plates 

 from his own drawings. Other memoirs by this author will be 

 found in the " PalcBontograpMca," of which he was one of the 

 editors. In the many volumes of this publication, which began
