every important family of Palaeozoic articulate Bracbiopods, and we 

 may tentatively assume that, as a rule, the essential features of 

 variation observed in any member of a genus will hold good of the 

 other members. In regard to the development of the characters of 

 the pedicle-passage, i.e. the deltidial plates and the foramen, there 

 is good reason to regard the process as substantially identical in all 

 the genera represented, making the necessary allowance for the 

 peculiar variation seen in the Strophomenidae, which may not, how- 

 ever, prove it an exception to the general statement." 



After criticizing the observations of M. Eugene Deslongchamps 

 in his "Note sur le developpement du deltidium chez les brachio- 

 podes articules " (Bull. Soc. Geol. France, 2 e ser. torn. xix. pp. 409 — 

 413, pi. ix. 1862), the authors sum up the results of their studies of 

 the cardinal area in these words : — " it is not improbable that from 

 an early form related to the genus Orthis, phylogenetic development 

 tended in two main channels. One leading through Strophomena, 

 Scenidium, Ortliisina, Leptcena, Chonetes, Prodvctus, and Strophalosia, 

 and the other in the .direction of Rhynchonella, Spirifer, Atrypa, 

 Retzia, and Terebratnla." 



We congratulate Messrs. Beecher and Clarke upon the production 

 of such a valuable instalment towards the complete developmental 

 history of the Brachiopoda. A. H. F. 



III. — The Vertebrate Animals of Leicestershire and Eutland. 

 By Montagu Browne, F.Z.S. (Midland Educational Company, 

 1889.) 



THE title of this work would scarcely lead the Palaeontologist to 

 expect any items relating to his province ; and the ordinary 

 naturalist will doubtless be surprised to find elephants, rhinoceroses, 

 bisons, reindeer, and crocodiles indiscriminately mingled with the 

 small " game " as elements of the Vertebrate Fauna of the counties 

 under consideration. However, notwithstanding the misfortune (as 

 we regard it) of confusing fragments of numerous successive faunas, 

 as if they all belonged to one period, Mr. Browne's volume is a most 

 welcome and important addition to the literature of the subject of 

 which it treats. The book carries out a plan we would be glad to 

 see followed by others specially conversant with the details of local 

 faunas, living and extinct; and its accuracy as a work of reference 

 is insured by the care with which the author has submitted all 

 points outside his own immediate province to the judgment of 

 several specialists. A systematic zoological arrangement is adopted 

 throughout, commencing with the genus Homo and ending with 

 Petromyzon ; and the latest results in taxonomy and nomenclature 

 are almost uniformly incorporated. The records of the bones and 

 teeth of Mammalia met with in Pleistocene and other superficial 

 deposits are chiefly based upon the collection in the Leicester 

 Museum, of which the work gives a tolerably complete catalogue. 

 In addition to evidence of man dating as far back as Neolithic 

 times, there are remains of Elephas primigenius, E. antiquus, 

 Rhinoceros (?) leptorhinus, Equns caballus, Bison jjriscus, Bos
