V. — British Fossil Bibds. 



ME. E. LYDEKKEE contributes a valuable article on British 

 Fossil Birds to the July Number of " The Ibis," containing 

 a critical summary of present knowledge of the subject. The article 

 occupies pp. 381-410 of the current volume, and treats in succession 

 the birds of the Superficial Deposits, those of the Pliocene Crags, 

 those of the Upper Eocene (Oligocene), those of the Lower Eocene, 

 and the few fragments from the Cretaceous. The researches 

 undertaken by the author for the recently published " Catalogue 

 of Fossil Birds in the British Museum " form the basis of the 

 Memoir; and it constitutes an important readable addendum to the 

 work just cited (see Eeview of Catalogue in August No. p. 378). 



YL — " Pantobiblion : An International Bibliographical Eeview 

 OF THE World's Scientific Literature." Edited by A. 

 Kersha, C.E. (St. Petersburg and London : Swan Sonnen- 

 schein & Co., 1891.) 



WE have received the first number of this new monthly, edited 

 and printed in St. Petersburg, and to be obtained in England 

 from Messrs. Swan Sonnenschein & Co. Nearly 300 pages are 

 occupied with classified lists of new scientific works and periodicals, 

 some of which are briefly reviewed. Under the heading " Geology 

 and Mineralogy " we find recorded several Inaugural Dissertations 

 and small separate publications such as are often overlooked by 

 workers. The new periodical will prove most valuable to all 

 engaged in scientific pursuits, and especially to those dealing with 

 applied science. 



VII. — Monograph of. the Fossil Species of Pristis. [Monografia 

 DEI Pristis FOssiLi con la Descrizione di una nova Specie del 

 Calcare mtocenico di Lecce.] By Dr. Giovanni Vigliarolo. 

 Mem. E. Accad. Sci. Napoli, [2] vol. iv. append. No. 3, pp. 1-28, 

 with plate. (1890.) 



AFTEE a definition of the genus Pristis and a partially critical 

 synopsis of all known species determined upon the evidence 

 of fossils. Dr. Vigliarolo proceeds to a detailed description of three 

 fragments of a rostrum, from the Miocene of Lecce, preserved in the 

 Geological Museum of the Naples University. The description is 

 illustrated by a large folding plate, and justifies the recognition of 

 a new species, Pristis lyceensis. SderorhyncJius and Propristis are 

 regarded as extinct genera of Pristidse, but Amhlypristis is considered 

 to be merely a synonym of Pristis. The known fossils are so frag- 

 mentary that they seem to be scarcely worthy the extended treat- 

 ment they have received at the hands of the author; but the result 

 of his investigations is a useful epitome of our present knowledge of 

 the subject.
