MAMMALIA. 243 



Under the article Petrefaktenkunde in the ' Allgemeinen 

 Encykl. der Wissensch. u. Kiinste von Ersch und Gruber/ 

 H. von Meyer lias afforded us an interesting glance at the 

 primo-mundaue Flora and Fauna, with special reference to 

 the Mammalia. A similar survey has been given by the 

 Reporter, in his ( Geschichte der Urwelt / Leipzic, 1841 and 

 45, at section 2, entitled ' Das Thier und Pflanzenreich der 

 Urwelt/ wherein he bestows greater attention likewise on 

 the Mammalia. ' Trait e elementaire de Paleontolgie on 

 Hist. NatureUe des Animaux fossiles considered dans leurs 

 rapports zoologiques et geologiques/ par F. J. Pictet; Geneve, 

 1844, torn. i. In this work Pictet aims at giving a 

 manual of Paleontology, yet one that bears reference only to 

 the animal kingdom. He has our thanks for the excellent 

 manner in which it is executed. The first volume is con-

 are very well delineated : 18 plates, by way of illustration, 

 accompany the work, and are of the same 8vo form. 



' A History of British Fossil Mammalia and Birds/ by 

 Richard Owen ; London, 1844. Parts i vi. This is a 

 thoroughly classical work, such as we are accustomed to 

 receive from the eminent Hunterian professor. It is not 

 confined simply to an enumeration of the primo-mundane 

 remains of Mammalia and Birds occurring on the British 

 islands, but is rich with his own investigations, and critical 

 examination, of the proposed species : 6 Nos. have appeared 

 in the course of the year 1844, the last of which breaks off 

 in the description of Mastodon angustideus. A number of 

 well-carved woodcuts serve to elucidate the text. Our 

 author has also given a Report on the British Fossil Mam- 

 malia, Part xi, concluding the Ungnlata, being in the 

 Report of the thirteenth meeting of the British Association, 

 held at Cork ; London, 1844, p. 208. J. Morris's ' Cata- 

 logue of British Fossils/ London, 1843, includes plants as 

 well as animals, giving the specific name of each, with 

 quotations of where the species have been described and 

 figured, besides the kind of rock and locality wherein each
