evidence of land connections with North America, that the Nolineae and Yucceae indicate 

 absence of any continental land connection, that Phoradendron and Furcraea suggest a 

 former land connection with North and South America, and that Agave furnishes strong 

 proof of a successively fragmented Antillean land bridge connecting with Central America 

 in the Yucatan region. — E. W. Berry.

 of Queensland. Parts 3 and 4.] Queensland Geol. Surv. Publ. 263. 76 p., 7 pi. 1919 — 

 Author records 36 species of plants from the Burrum series of Queensland, concluding that 

 the age is Lower Cretaceous. Several of the more interesting forms are figured and new 

 species are described in Sphenopteris, Phyllopteris, Microphyllopteris, Zamites, Taeniopteris 

 and Araucarites. The North American genus A T ageiopsis is tentatively recognized from these 

 beds. The Styx series contains but 14 species but is of great interest since among an assem- 

 blage of old types characteristic of the Burrum series it contains a considerable number of 

 dicotyledonous types some of which are referred to the form genus Celastrophyllum which is 

 so common in the Albian and Cenomanian rocks of North America. — E. W. Berry.

 Fig. 1-5. 1919. — Presidential address, containing a summary of our knowledge of the fossil 

 floras of Queensland. These include Paleozoic, Triassic, Jurassic, Cretaceous and Tertiary 

 floras. Chief emphasis is given to the Mesozoic floras, which are well represented in Queens-
