REFRESHER COURSE: METAMORPHOSIS IN THE ANIMALKINGDOM

At the 1956 meeting of the AmericanSociety of Zoologists a program of paperswas arranged with the theme: Recent Ad-vances in Invertebrate Zoology, and par-ticipants were urged to present synopsesdesigned to be of value to the general zoolo-gist. The enthusiasm for such programshas justified their continuance, and particu-larly because of their value to teachers, theNational Science Foundation has gener-ously given financial support. This supporthas made it possible to secure participationby the best qualified scientists, includingspecialists from overseas. Other RefresherCourse topics have been Advances in Proto-zoology, Recent Advances in the Study of

Animal Behavior, Evolution, and the pres-ent one.

The refresher course presented at Still-water, Oklahoma, in August, I960, was ar-ranged by Sheldon Segal with the topicMetamorphosis in the Animal Kingdom.He also undertook to secure manuscriptsfrom participants for publication in thisfirst issue of American Zoologist. It may benoticed that two of these have been ex-tended into comprehensive reviews, andthat a paper has been included which wasnot presented,—this by an invited authorunable to attend.
