Sanborn of the same institution on bats; Dr. H. W. Setzer, United States National Museum, on other mammals; and Mr. A. Loveridge, Museum of Comparative Zoology, on reptiles. Dr. C.W. Sabrosky, United States National Museum, has kindly answered questions on several nomenclatorial problems that arose during the course of this work. To Mr. R. Strekalovsky of Cairo University, appreciation must be expressed for the care with which he has prepared the illustrations in this report. It is also a pleasure to acknowl edge the services of Miss Marcelle Boshi and Mrs. Mary Youakim of Naval Medical Research Unit Number Three for their careful typing of the manuscript in its numerous preliminary forms, as well as in final form.

These are acknowledged in the title of each figure so obtained.
