corrclation, as well as to the botanical character and distribution of 

 the flora. One hundred and sixtyfive species of fossil plants are 

 carefully described and the more important are figured. New species 

 are described in Sphaerites, Asple>üu»i , and Phyllites. The new genus 

 Newberryana of uncertain aflinities is established for Hansmamiia 

 rigida Newberry. ßerry. 



Berry, E. W., The Low er Cretaceous Floras ofthe World. 

 (Maryland Geological Survey, Lower Cretaceous, p. 99—151. taf. 1 

 1911.) 



This is a chapter introductory to the correlation and descrip- 

 tion of the Lower Cretaceous floras of Maryland and consists of an 

 enumeration and discussion of the known floras from the Neoco- 

 mian, Barremian, Aptian and Albian stages throughout the 

 world. Lists of species are given for each area, the location of the 

 latter being indicated on a small sketch map of the world. The 

 general character, evolution and migration of these floras are indi- 

 cated and something is said of the physical conditions which they 

 indicate. < Berry.

 graphy and the history of their study fully treated, the whole for-

Devoted to a description of Carpolithus macrophylhts sp. nov. 

 from the Miocene shales of Florissant, Colorado. The fruit is 

 described as consisting of small woody follicles with four large per-

 Lyonothamnus. Berry.
