INSTRUCTIONS FOR CONTRIBUTORS

Contributions and correspondence about them should be sent to Professor D. R. Newth, Department of Zoology, The University, Glasgow, W. 2, Scotland, U.K.

Contributions should be as concise as possible. They should be typewritten, double-spaced, on one side of the paper, and the pages numbered. They should be fully ready for press, since revision in proof will not be possible. Footnotes should be avoided. The author is advised to keep a copy of the typescript.

T A B L E S should be in typescript on separate sheets, and numbered. Authors should indicate the places for their insertion in the margin of the typescript. Authors are asked not to submit tables in the form of photographic prints. No tables should be submitted that are too large to be printed on one page.

T H E S U M M A R Y should be in numbered paragraphs and at the end of the text. It should not exceed 500 words. The author may provide a translation of the summary into a second language. If he does not an extra copy of the summary should be sent for translation purposes.

A C K N O W L E D G E M E N T S should be placed immediately before the list of references.

R E F E R E N C E S should be listed alphabetically. In the text they should be referred to by the author's name and the year of publication. If more than one reference to the same author and year is quoted, use suffixes a, b, etc. (e.g. 1951 a) in text and reference list. Papers and books should be listed as shown in the examples given below. Journal names should be given the World List of Scientific Periodicals abbreviation.

(i) Line drawings should be used wherever possible, in preference to illustrations requiring half-tone reproduction. If possible the size of all illustrations submitted should be such that they are reduced for publication to approximately two-thirds linearly. If very large figures are submitted small photographic prints of them should also be included for use by referees. When reduced, no illustration or page of illus­trations together with its lettering can exceed five inches in width, and seven and a half inches in length. Name of author and figure number should be written on the back, together with the proposed reduction in size. Magnification should be indicated by a scale-line drawn in Indian ink on or beside illustrations.

(ii) Black and white line, or line and dot, drawings should have all lettering or numerals put in lightly in block capitals with a soft pencil. Charts and graphs may be drawn in Indian ink on graph paper ruled in pale blue. Where several drawings are grouped as one figure, they should be distinguished by capital letters (in pencil). Legends for all line drawings should be typed together on a separate sheet. The places for insertion in the text should be indicated in the margin of the typescript. The drawings should be referred to in the text as 'Text-fig. 1 ', etc.

(iii) Half-tone illustrations (photographs or drawings other than black and white) will be limited in number: authors may be asked to pay for an excessive number. If fine detail is required they should be arranged as a separate plate, mounted on stiff white card. The legends should be typed on a separate sheet, headed ' Explanation of Plate(s) ', and the illustrations should be referred to in the text as ' Plate 1, fig. A ', etc. If fine detail is not required they can be reproduced as text-figures (please indicate position), in which case they should be numbered in series with the line drawings, if any. Leader lines should be drawn in Indian ink. AH letters or numerals which are to go on or beside the illustrations should be in pencil (block capitals) on a covering sheet of transparent paper. Photographs should be glossy bromide prints.

(iv) Coloured plates can be reproduced provided the author meets the additional cost.

P R O O F S . Authors will receive one set of proofs for correction and return to the Editor. Authors may be required to pay for alterations in proof other than those needed to correct printer's errors.

R E P R I N T S . Authors will receive fifty free reprints. Additional copies may be ordered for purchase when proofs are returned to the Editor.
