This journal is especially offered in exchange for zoological and entomological journals, proceedings, transactions, reports of societies, museums, laboratories and expeditions. The pages of the journal are especially open to western entomologists and zoologists. Notes and papers relating to western and Californian forms and conditions are particularly desired, but short morphological, systematic or economic studies from any locality will be considered for publication. Manuscripts submitted should be typewritten on one side of paper about 8 by 11 inches. Foot notes, tables, explanations of figures, etc., should be written on separate sheets. Foot notes and figures should be numbered consecutively throughout. The desired position of foot notes and figures should be clearly indicated in the manuscript. Figures should be drawn so that they may be reproduced as line cuts so far as possible. An unusually large number of half tones must be paid for in part by the author. Other more expensive illustrations will be furnished at cost. Figures for cuts should be made to conform to the size of the page when reduced, that is, 5 by 7-1/2 inches or less. The lettering should be by means of printed numbers and letters pasted on the drawings, in most cases.

If more than this are desired, the order should be given with the return of the proof sheets. Extra copies and special covers or special paper will be furnished at cost.
