Directs attention to the value of material which may often be 

 discovered in swamps where the remains of Vegetation have been 

 accumulating for an indefinite period. The paper has special refe- 

 rence to the Lignite beds of the Clif f wo od BrickCo., at Whale 

 Creek, New Jersey, where are to be found deposits of amber, 

 several important coniferous plants, Myrica etc., remains of which 

 are readily obtained by washing. D. P. Penhallow. 



Berry, E. W., A Note on Mid-Cretaceous Geograph y. 

 (Science. N. 8. XXIII. 1906. p. 509—510.) 



Reference is made to recent evidence adduced by Prof. H. F. 

 Osborn as to the probable geographical unity of North and 

 SouthAmerica during the Mid-Cretaceous period, and continuing 

 until early Tertiary time. The author points out the striking simi- 

 larity of plant types in the Cretaceous of North and South 

 America, especially as disclosed by the studies of Kurtz with 

 respect to the plant remains of Argentina, which are shown to 

 have a very marked Cenomanian facies with a remarkable similarity 

 to the Mid-Cretaceous flora of the Central western United 

 States. The conclusion is reached that there was a definite con- 

 nection between North and South America during Mid- 

 Cretaceous time, but that while the plant beds were homotaxial, they 

 were not synchronous, the time interval being that which was ne- 

 cessary for the northern flora to spread from about the latitude of 

 Texas to that of Patagonia. D. P. Penhallow. 



Bonnet, E., Contribution ä la flore pliocene de la pro- 

 vince de Bahia (Brasil). (Bull. Museum bist. nat. 1905. 

 p. 510—512.) 



Les plantes mentionndes dans ce travail ont €i€ recueillies par 

 M. Glaziou dans le gisement pliocene d'0uri9anga, dont la 

 flore a fait l'objet d'un des derniers travaux de C. von Ettings- 

 hausen; ä cötd d'especes ddjä decrites par ce dernier, M. Bonn et 

 a observd des formes qui ne semblent pas pouvoir etre distingudes 

 d'especes vivant encore dans la r^gion; il semble d'ailleurs que les 

 conditions climatdriques locales n'aient pas du se modifier sensible- 

 ment depuis l'^poque pliocfene. Les espfeces reconnues sont les 

 suivantes : Cyathea praebenina Ett., feuilles de Palmier, Ficiis sp. 

 trfes voisin du F. anthelminthica Miq., Ficus sp., Artocarpidium
