I / \.^ I HARVARD UNIVERSITY LIBRARY OF THE Museum of Comparative Zoology -f^h- NUuJ ^l^3y) S 3 '^^C^ VOLUME 15 1968-1969 TULANE UNIVERSITY NEW ORLEANS TULANE STUDIES IN ZOOLOGY AND BOTANY is devoted primarily to the biology of the waters and adjacent land areas of the Gulf of Mexico and the Caribbean Sea, but manuscripts on organisms outside this geographic area will be considered. Each number is issued separately and contains an individual monographic study, or several minor studies. As volumes are completed, title pages and tables of contents are distributed to institutions receiving the entire series. Manuscripts submitted for publication are evaluated by the editor or associate editor and by an editorial committee selected for each paper. Contributors need not be members of the Tulane University faculty. The editors of Tulane Studies in Zoology and Botany recommend conformance with the principles stated in chapters I and II (only) of the Style Manual for Biological Journals, 2nd ed., published in 1964 by the American Institute of Biological Sciences, Washington, D. C. Manuscripts should be submitted on good paper, as original typewritten copy, double- spaced, and carefully corrected. Two copies, carbon or other suitable reproduction, must accompany the original to expedite editing and assure more rapid publication. Legends for figures should be prepared on a separate page. Illustrations should be proportioned for one or two column width reproductions and should allow for insertion of legend if occupying a whole page. An abstract not exceeding three percent of the length of the original article must ac- company each manuscript submitted. This will be transmitted to Biological Abstracts and any other abstracting journal specified by the writer. The editors also recognize the policy adopted by the Federal Council for Science and Technology, and endorsed by the Conference of Biological Editors, that page charges for publication of scientific research results in scientific journals will be budgeted for and paid as a necessary part of research costs under Federal grants and contracts. Accord- ingly, writers crediting research grant support in their contributions will be requested to defray publication costs if allowable under the terms of their specific awards. Illustrations and tabular matter in excess of 20 percent of the total number of pages may be charged to the author; this charge is subject to negotiation. Exchanges are invited from institutions publishing comparable series but subscriptions are available if no exchange agreement can be effected. Separate numbers or volumes can be purchased by individuals and subscriptions are accepted. Remittance should accompany orders from individuals. Authors may obtain separates of their articles at cost. Address all communications concerning manuscripts and editorial matters to the editor; communications concerning exchanges, and orders for individual numbers to Dr. Royal D.
