Pinus, the true Pines, iu 1735; Abies, the Silver Firs, in 1737; 

 Larix, the Larches, in 1763. Link separated the Spruces or Pitch- 

 Trees from true Abies iu 1827, under the generic name Picea. 

 Moi'e recently, in 1855, Carriere split up Link's Abies into Firs and 

 Hemlock Spruces, naming the latter as a genus, Tsiiga; in 1867 he 

 distinguished as distinct from Tsuga the genus Pseudoisuga, or 

 False Hemlock Spruces. In 1890 I still further restricted the 

 generic name Tsuga by describing the Alpine Western Spruce 

 under that of Hesperopeuce- 



THE NEW SERIES OF PROCEEDINGS OF THE CALI- 

 FORNIA ACADEMY OF SCIENCES. 



Important changes have recently been made by the California 

 Academy of Sciences in its jDnblications. The great increase in 

 scientific research that has recently taken place in California has 

 brought the question of means of publication prominently before 

 the minds of local scientific workers. Any method of scientific 

 publication that would deserve the approval of scientific men must, 

 in view of the already enormous and rapidly-increasing volume of 

 periodical scientific literature, regard most carefully the convenience 

 of the users of this literature. Further, it is the desire and the 

 effort to give such form and character to the publications of the 

 Academy as shall make them become the chief depository of the 

 results of all researches in pure science that relate to nature iu 

 California and on the Pacific Coast of the United States. With 

 these considerations, and others of local importance in view, the 

 administration of the Academy has adopted the following plan with 

 reference to its publications, which, it believes, furnishes the best 

 solution practicable to the publication question. Beginning with 

 the next volume, the first of the Third Series, the Proceedings Avill 

 be issued in several wholly independent divisions, or parts, each 

 division to be devoted to a single branch of science, or to a group 

 of closely-related sciences. There will be begun at once three 

 divisions, viz., for Geology, for Botany, for Zoology, and from time 

 to time such others as may be demanded, and as the finances of the 

 Academy will permit. Papers will be issued separately, and will
