 An. Soc. Espan. Hist. Nat. vol. iii. part 3. 



Describes the Urgonian and Aptian deposits, esp.ecially those of 

 Eastern Spain in the Provinces of Castellon, Tarragona, and Teruel; 

 and proposes to name them Urgo-Aptian or Tenentian, the region of 

 ancient Tenentia in the Province of Castellon proving their intimate 

 connexion, and affording a great number of characteristiQ fossils. A 

 catalogue of 201 genera and 968 species of fossils accompanies the 

 paper. J. M*P.

MacPherson, Joseph. Memoria sobre la estructura de la Serrania 

 de Ronda. Cadiz. 



Describes the orographical structure and geological formation of that 

 part of the Province of Malaga which lies to the left of the river 

 Guadiaro. Nearly all the series, from the Paleozoic rocks to the 

 Pliocene deposits, occurs in this district. The most important fact 

 brought forward is the existence of an enormous mass of Serpentine, 

 about 42 kilometres long, and about 18 to 20 kilometres in maximum 

 width, lying between the " Meseta de Ronda " and the sea, the up- 

 heaval of which appears to have been the main cause in imparting their 

 present relief to those mountains. A geological map and a plate of 7 

 sections are given. J. M*P.
