The Gasteropods of the Tertiary Deposits of Portugal. 407 



laceous shales and marls, containing numerous remains of Mollusca 

 (Ostrea montis-caprilis, etc.). The most abundant species of plants 

 are — Pecopteris Steinmillleri, Heer ; Equisetites arenaceus, Schenk ; 

 Calamites arenaceus, Jaeg; and Pterophyllum Jaegeri. The more 

 locally-occurring species are Pterophyllum longifoUum, P. Haidingeri 

 (fine specimens with leaflets occasionally one and a half inches in 

 breadth), and a species of Pterophyllum, with leaflets half-an-inch in 

 breadth and very long, perhaps P. Gumbeli, Stur. — Count M. 



TTT. — Zone of Anmonites transversakitjs. — Dr. Waagen has 

 edited, and communicated to the Imperial Geological Institute of 

 Vienna (Meeting, Jan. 5, 1867), a paper of the late Dr. Oppel, concern- 

 ing the Upper Jurassic Zone, characterized by the presence of Am- 

 monites transversarius, limited above by the zone of Terebratula im- 

 pressa, and below by the zone of Ammonites cordatus. The zone in 

 question is to be traced from south-west Poland through the Car- 

 pathians, Moravia, Bavaria, the Schwabische Alps, the Swiss Jura, 

 the Alps, France, Spain, as far as Algeria. The number of fossil 

 species known to occur in it amount to 217 ; among them are mi- 

 croscopic remains of Crustacea and Eadiata, and many new species 

 of Foramiaifera. 



IV. — ^Mammalian Eemains from Hungary. — M. de Hantken has 

 recorded the following mammalian remaius from a Post-Pliocene 

 deposit at Fiinfkirchen, in Hungary: — Ursus spelceiis, many frag- 

 ments of lower jaws, loose teeth, and vertebrte ; Hymna spelcsa, Goldf., 

 a fragment of a jaw belonging to a young animal, with the first 

 teeth and protruding canines ; Eqiius fossilis, Cuv., a fragment of 

 a lower jaw with a tooth ; Bos priscus, Boj., a second collar vertebra; 

 BMnoceros ticliorJiinus, Cuv., a single tooth. — Proceed. Imp. Geol. Inst., 

 Vienna, Dec. 18, 1866. 



V. — The Gasteropods of the Tertiary Deposits op Portugal. 

 By Pereira Da Costa. 



[Gasteropodes dos depositos Terciarios de Portugal, por Pereii-a Da Costa, com a versao 

 Franceza por M. Dalhunty. lo. Cademo, 4to. Lisbon, 1866.] 



THE pages of this work are divided into two columns, one con- 

 taining the original Portuguese of Seiior Da Costa, the other a 

 French Translation by M. Dalhunty, wliich will be very useful to 

 those unacquaiuted with the Portuguese language. This first part 

 contains 116 pages of letter-press and 15 excellent lithographic plates. 

 The author has followed Lamarck's classification in his descrip- 

 tion of the fossils, and explaias that it is not through want of 

 appreciating the great amelioration since introduced into the methodic 

 distribution of the Mollusca, but on account of the great convenience 

 in modelling the work on that of M. Homes, descriptive of the fossil 

 Gasteropods of the Vienna basin, which being a deposit very similar 

 to that in Portugal, contains the greater part of the species met with 

 in Portugal.
