Excerpt from Extinct and Vanishing Mammals of the Western Hemisphere, Vol. 11: With the Marine Species of All the Oceans

Dr. Francis Harper, of Philadelphia, under arrangements made by Dr. Phillips, undertook this work and devoted many months of care ful research to the preparation of material on the Old World mammals, treating in his report (as yet unpublished) about 400 forms. Dr. Allen made use of a special bibliography of references to literature collected by Dr. Harper, and with this as a basis prepared the present work on the New World and marine mammals, assembling much additional material to complete it.

The harper-allen study could never have been brought to its present state of completion had it not been for the most generous financial assistance received in the form of gifts from many individual over a period of seven years, a special grant from the Penrose Fund of the American Philosophical Society (1937, No. And a publi cation grant from the Boone and Crockett Club and the Conservation Committee of the New York Zoological Society.
