form, for the use of geologists, what is definitely known of the 

 stratigraphic occurrence of the species of Echini described in 

 Doctor Jackson's paper. 



No. 308. Plant Habits and Habitats in the Arid Portions of 

 South Australia; by W. A. Cannon. Octavo. Pp. viii, 139, 32 

 pis., 31 figs. ($2.75). — This is a careful investigation of the 

 physical environment of the vegetation of different sections of 

 South Australia, with details as to rainfall, evaporation, relative 

 humidity, etc. Dr. Cannon has previously issued a somewhat 

 similar work on the Algerian Sahara (publication No. 178). 



No. 311. Shallow-water Foraminifera of the Tortugas Region ; 

 by J. A. Cushman. (Papers from the Department of Marine 

 Biology, Vol. XVII.) Octavo. Pp. 85, 14 pis. ($1.50).— This 

 work gives the results of the study of some of the living foramini- 

 fera which have been very rarely studied in tropical waters. The 

 relationships of the fauna to other regions is discussed and a gen- 

 eral systematic treatment of the local foraminifera is given in 

 detail. The new and rare species are illustrated by numerous 

 plates. 



No. 314. The Behavior of Stomata; by J. V. G. Loftfield. 

 Octavo. Pp. 104, 16 pis., 54 figs. ($1.50).— This treatment of 

 stomatal behavior falls into three divisions. The first is descrip- 

 tive, and deals with the hourly stomatal movement for a 24-hour 

 day of a considerable number of species, including trees, shrubs, 

 and a wide variety of herbs, both cultivated and native and of 

 different ecological character. The second deals with causes of 

 changes in stomatal movement from day to day, as well as during 

 the daily march. The third deals with the effect of stomatal 

 movement upon transpiration. 



2. Proceedings of the First Pan-Pacific Scientific Conference, 

 held under auspices of the Pan-Pacific Union. Three volumes, 

 1921. — It is well known that the first Pan-Pacific scientific con- 

 ference, held in the summer of 1920 at the Bishop Museum in 

 Honolulu, was a far-reaching and stimulating success, and some- 

 thing of the results there attained are here set forth in printed 

 form. The three volumes contain about 180 papers, totalling 

 949 pages, relating to almost every phase of science in the realm 

 of the Pacific and its bounding continents and continental islands. 

 Most of them are suggestive of things yet to be done, but many 

 record valuable observations. The feeling of the chairman of the 

 Conference, Herbert E. Gregory, is one of optimism that men and 

 means will lie found to unravel, if not all, at least most of the 

 major problems connected with the natural history of the Pacific 

 region. c. s.
