Type of Haematopinus callorhini Osborn is not in the collections of the U.S. National Museum, Ohio State University, or Iowa State University and may be lost (Kim, 1971), but Ferris (1934, pp. 495-96) wrote,“Known only from the original record by Osborn from Callorhinus alascanus. Pribilof Islands, Alaska. The specimen, without host or locality data, upon which the description of A. monachus Kellogg and Ferris was based, now appears without doubt to have come from this same lot.” Male holotype of A. monachus, in the Ferris Collection, Department of Entomology, University of California, Berkeley.
