From reviews of the previous edition

"The island nation of Trinidad and Tobago has long served as a window on South American birdlife. Birders have been visiting the two islands in large numbers since the 1960s, when Asa Wright converted an unproductive plantation into one of the first neotropical 'ecotourist traps.' Anyone traveling to Trinidad and Tobago shouldn't leave home without this work." Journal of Field Ornithology

"This book will be wanted by any birder visiting Trinidad and Tobago, as well as by many ornithologists as a general reference." Wilson Bulletin

Members of nearly all the families of South American birds can be found on the two beautiful West Indian islands of Trinidad and Tobago, where the pleasant climate, varied habitat, and avian diversity create a "birder's paradise." This easy-to-use book is the third edition of a comprehensive yet compact field guide to all 477 species of the islands' birds, including 35 new species accounts added to the country's bird list since the last edition. Richard ffrench s work has been a "bible" to birders since the appearance of the first edition in 1973. This new edition incorporates five decades of his notes and records of the island s birds to present in a handy and readable form detailed and comprehensive information about the birds of Trinidad and Tobago.

Showcasing 40 all-new color plates by the very best bird artists working under the direction of John P. O Neill, the third edition now includes illustrations of not only the islands endemic and resident species, but also the many migratory species that visit the islands from both the north and the south. The taxonomic arrangement and treatment of families and species has also been brought in line with the most recent determinations of the A.O.U. Committee on Nomenclature for a thoroughly up-to-date presentation. In his introduction, Richard ffrench offers a full treatment of the history of ornithology in Trinidad and Tobago and sets the scene by describing the islands physiography, climate, and vegetation. Individual species accounts, arranged by family, make up the core of this identification guide. The accounts cover habitat and status, range and subspecies, field description and basic measurements, voice, food, nesting, and behavior. Richard ffrench s summary of the distribution of species and their breeding and migration, as well as local conservation and protection measures, makes this volume much more than a typical field-guide treatment, and invites visitors to this premier ecotourism destination."

Butterfly Wing Patterns and Mimicry, Volume 54, provides an essential reference for those interested in molecular Entomology and the study of natural selection. The volume spans work on the genetics of polymorphism in Heliconius butterflies through to a detailed analysis of the role of CRISPR-CAS in dissecting wing patterning. The volume covers both the evolution and fine scale development of both pattern and pigmentation. The role of wing shape is also considered for the first time in a formal analysis. It should be of interest to both experts and students interested in Entomology and its application to fundamental questions in evolution.

MUSIC AND CRITICISM A SYMPOSIUM EDITED BY RICHARD E. FRENCH t, t HARVARD UNIVERSITY PRESS Cambridge, Massachusetts 1948 COPYRIGHT, 1948 BY THE PRESIDENT AND FELLOWS OF HARVARD COLLEGE NORWOOD PRESS S. GUSHING CO. BERWICK AND SMITH CO. C. B. FLEMING CQ. NORWOOD, MASSACHUSETTS, U. S. A. r PREFACE The addresses which appear in this small volume were delivered at a Symposium on Music Criticism, held at Harvard University, Cambridge, Massachusetts, dur ing the first three days of May, 1947. The meetings and concerts of the Symposium were attended by more than eight hundred guests of the University, representing a variety of musical professions and interests, who came to Cambridge from more than forty states. The Sym posium was conceived, formulated, and executed under the direction of Professor A. Tillman Merrin, Chair man of the Department of Music in Harvard University, and was financed through the generosity of Mrs. A. W. Erickson, Mr. and Mrs. John Nicholas Brown, Profes sor Walter Piston, and the Elizabeth Sprague Coolidge Foundation in the Library of Congress. For further ad vice and assistance, the Department of Music is indebted to Provost Paul H. Buck, to the curators of the Lucius W. Nieman Foundation, to Professors Theodore Spen cer, Paul Sachs, and Harry Levin, and to Mr. William Pinkerton of the Harvard University News Office. It is tempting to allow these papers to speak for them selves, to refrain from any comment whatsoever. Pro fessor Davisons introductory remarks reveal the feel ing of the Department that someone ought to do t JM vi PREFACE something about music criticism, and the titles of the addresses, which were selected by the Department to be delivered in the order inwhich they appear in this volume, indicate the topics which the Department felt could be treated to advantage in such a series of meet ings. The papers of Mr. Forster and Mr. Sessions were to deal with critical problems of a general and philo sophical nature those of Mr. Wind, Mme Samaroff, and Mr. Thomson were to take as their point of departure the discussion of individual works of art from the stand point of the creator, the interpreter, and the audience and those of Mr. Kinkeldey, Mr. Lang, and Mr. Cairns were to treat technical matters of immediate importance. The reader should bear in mind, however, that the Sym posium was conceived not as a sequence of meetings which would give final answers to difficult questions, but as the initial impulse to a succession of thoughts and actions which might contribute to the effectiveness of the music critic in our musical life. This was the specific purpose of the Symposium, and it is worth a preface to state it in plain language because by so doing, attention can be drawn to at least three ideas which are engagingly and disastrously easy to infer First, that the well-trained music critic is the panacea for all our musical ills. This is patent nonsense. The music critic can be effective only in so far as he is a useful member of a society which wants and uses music and though a discussion of music in our society can be approached from the standpoint of the duties and re PREFACE vii sponsibilities of the music critic, the discussion be comes abstract and futile if it fails to consider all the other factors musical and non-musical which affect those duties and responsibilities and vice versa. The com poser, the scientist, and the businessman, toname only three and to understate the case, are of equal importance with the critic in directing a satisfactory musical ex pression. Second, that the music critic can find in these papers a resolution of all his difficulties. This is precisely what he cannot find, search as he will. What he may come upon is a series of ideas and observations which may help him to think more clearly about his profession. But thinking is only a portion of his lot...
