Two species of coniferous wood have been described by Felix 

 from Galicia, which he names Cormocedroxylon jurense and 

 Cladocedroxylon Auerbachii, from the Braun Jura and Lower 

 Kimeridgian respectively. 1 



ITALY. 



By far the most important contribution to the Mesozoic Botany 

 of Italy is that by Zigno, published in parts between 1856 and 

 1885. 2 In a preliminary paper published in 1853, Zigno 3 drew 

 attention to the close similarity of the recently discovered Lower 

 Oolite (Bathonian) plants of the Venetian Alps with those from 

 East Yorkshire. Among the Italian plants the following may be 

 mentioned as nearly allied to or identical with British Inferior 

 Oolite species ; the Venetian flora is rich in Cycads, the genus 

 Otozamites being especially well represented.
