11. Size and Arrangement of Drawings.—The printed plate will not exceed 7¼ in by 4½ in, and drawings for plates may be to this size, or preferably a multiple thereof, maintaining the same proportion of height to width of plate. When a number of drawings are to appear on one plate they should be neatly arranged, and if numbered or lettered in soft pencil the printer will mark them permanently before reproduction. In plates of wash drawings, all the subjects comprising one plate should be grouped on the same sheet of paper or cardboard, as any joining-up shows in the print. Text-figures should be drawn for reduction to a width not exceeding 4⅓ in. If there are a number of small text-figures they should be drawn all for the same reduction, so that they may be arranged in groups. In the case of plates composed of a number of separate figures, the latter should be arranged by the author in groups of appropriate dimensions. Alternatively, exact instructions as to proposed arrangement of figures should be included with the Ms. 12. Maps.—A small outline map of New Zealand is obtainable at a low price from the Lands and Survey Department, Wellington, upon which details of distribution, etc., can be filled in according to the instructions given above for line drawings. 13. Citation.—References may be placed in a list at the end of an article or arranged as footnotes. The former method is preferable in long papers. In the list references must be arranged alphabetically reference in the text being made by writing after the author's name, as it occurs, the year of publication of the work, adding, if necessary, a page number, and enclosing these in parentheses, thus: “Benham (1915, p. 176).” Example of forms of citation for alphabetical list: Benham, W. B., 1915. Oligochaeta from the Kermadec Islands. Trans. N.Z. Inst. vol. 47, pp. 174–285. Park, J., 1910. The Geology of New Zealand, Christchurch, Whitcombe and Tombs. When references are not in alphabetical order the initials of the author should precede the surname, and the year of publication should be placed at the end. Care should be taken to verify the details of all references—date, pages, etc.—and initials of authors should be given. 14. In accordance with a resolution of the Council, authors are warned that previous publication of a paper may militate against its acceptance for the Transactions. 15.

Additional copies may be obtained at cost price. [The present rate is 1s 3d per page for 100 extra copies; thereafter 3d per page for each additional 25 copies.
