October 7, 1935 This catalogue of vertebrate specimens for use in Zoology 116 (Economic Vertebrate Zoology) and Zoology 113 (Natural History of Vertebrates) was begun in order to record the specimens at hand so that they would be more easily used in instruction. The material now at hand consists of a diverse lot of material assembled from many places and, on the average, not in good condition. In general there are three sources of this material (1) old material, mostly birds, purchased or given to the Department of Zoology, (2) Recently purchased material collected by Dawson A. Feathers, and (3) specimens collected locally by members of the Museum of Vertebrate Zoology, graduate students, and students in Zoology 113 and 116. All the material worth preserving is to be numbered beginning with no. 1, regardless as to whether or not attempts to number them have been made before. As far as I can find out, there is no previous catalogue for this material extant. In cataloging any accession, a description of the source and kind of material should precede the actual work of recording the data in the catalogue. Mammals, birds, reptiles, amphibians, and fish are each to be recorded separately, that is to say, there will be a serial list of numbers for each class. In the future, missing or discarded specimens should be eliminated from the catalogue. Seth B. Benson
