Instructions to Authors of Papers The attention of authors is particularly directed to the following instructions, the observance of which will greatly aid the work of both Editor and printer. 1. All papers must be typewritten, unless special permission to send in written papers has been granted by the Editor for the time being. Wide spacing between the lines and ample margin should be left. 2. The author should read over and correct the copy before sending it to the Editor of the Transactions. 3. A badly arranged or carelessly composed paper will be sent back to the author for amendment. It is not the duty of an editor to amend either bad arrangement or defective composition. 4. In regard to underlining of words, it is advisable, as a rule, to underline only specific and generic names, titles of books and periodicals, and foreign words. 5. In regard to specific names, the International Rules of Zoological Nomenclature and the International Rules for Botanical Nomenclature must be adhered to. 6. Titles of papers should give a clear indication of the scope of the paper, and such indefinite titles as, e.g., “Additions to the New Zealand Fauna” should be avoided. 7. Papers should be as concise as possible, and the number of figures should be strictly limited. 8. Photographs intended for reproduction should be the best procurable prints, sent flat. 9. Line Drawings.—Drawings and diagrams may be executed in line or wash. If drawn in line—i.e., with pen and ink—the best results are to be obtained only from good, firm, black lines, using such an ink as Higgin's liquid India ink, or a freshly mixed Chinese ink of good quality, drawn on a smooth surface, such as Bristol board. Thin, scratchy, or faint lines must be avoided. Bold work, drawn to about twice the size (linear) of the plate, will give the best results. Tints or washes may not be used on line drawings, the object being to get the greatest contrast from a densely black line drawn on a smooth white surface. 10. Wash Drawings.—If drawing in wash is preferred, the washes should be made in such water-colour as lamp-black, ivory black, or India ink. These reproduce better than a neutral tint, which inclines too much to blue in its light tones. High lights are better left free from colour, although they may be stopped out with Chinese white. As in line drawings, a fine surface should be used (the grain of most drawing-papers reproduces in the print with bad effect), and well-modelled contrasted work will give satisfactory results.
