VERTEBRATE PALAEONTOLOGY IN 1910 691 



decade 5, vol. vii. p. 402, on a new sole {Solea eocenica) and 

 eel (Mylomyrus frangcns) from the Egyptian Eocene ; the 

 second of these also representing a new genus. 



Remains of various fishes from the Upper Silurian of 

 Portugal, of which one is new, form the first portion of a 

 paper by Mr. Priem published in Communicafoes Serv. Geol. 

 Portugal, vol. viii. 10 pp. 



The Oligocene fishes of Belgium are described at consider- 

 able length by Mr. Maurice Leriche in the Mem. Miis. R. Hist. 

 Nat. Belgiqiie, vol. v. pp. 231-363. The species are ranged 

 under two series, namely a small one from the Tongrien, 

 and a larger one from the Rupelien horizon. None of the 

 species is new ; and those of the Rupelien stage indicate 

 a littoral fauna, containing representatives of several genera 

 still living on the coast. As a whole, the fish-fauna of the 

 Oligocene of Belgium is of a somewhat more temperate nature 

 than that of the Eocene, which is distinctly tropical. Most 

 of the Oligocene forms appear to be new types, although a 

 considerable number are derivatives from those of the Eocene. 

 A few species are common to both horizons. Reference may 

 likewise be made to the continuation by Dr. Smith Woodward of 

 his monograph of the fishes of the English Chalk in the volume 

 issued by the Palaeontographical Society for 1910; chimaeroids 

 and elasmobranchs forming the subject of this fasciculus. 



Another fish-paper, dealing mainly with sharks and rays, 

 by Mr. G. Stefanu, entitled " Osservazioni sulla Ittifauna 

 Pliocenica di Orciano e San Quirico in Toscana," is issued 

 in the Boll. Soc. Geol. Ital., vol. xxviii. p. 539-648. 



An equally brief notice must serve in the case of a memoir 

 by Prof. G. de Alessandri on the Triassic fishes of Lombardy, 

 published in Mem. Soc. Ital. Set. Nat. e Mits. Civ. Storia Nat. 

 MilanOy vol. vii. pp. 1-145, and containing descriptions of a 

 few new species and notes on many others. 



Otoliths and other fish-remains from the pisciferous shales 

 of Transbaikalia form part of the subject of a memoir by 

 Mr. O. M. Reis, published in part 29 of Recherches geologiqites 

 et minieres le long du Chemin de Fer, Siherie. These shales 

 are largely developed on the left bank of the We'tiser River, 

 and appear to be of Mesozoic age, A nearly complete fish 

 is made the type of a new genus and species, under the name 

 of Stichopterus woodwardi.
