For those asking about A.H. Howell, author of Revision of the North American Ground Squirrels (1938), the source of the illustration of the ring-tailed ground squirrel by Ernest E. Thompson, alias of Ernest Thompson Seton (Aug. 14, 1860-Oct. 23, 1946), co-founding pioneer of Boy Scouts of America (this post's sixth image; seventh image from the bottom):
Lake Grove, New York-born American zoologist (especially mammalogist and ornithologist) Arthur Holmes Howell (May 3, 1872-July 10, 1940) secured a temporary appointment in 1895 with American mammalogist Vernon Orlando Bailey (June 21, 1864-April 20, 1942) of the U.S. Department of Agriculture (USDA), Division of Ornithology and Mammalogy (later the Bureau of Biological Survey; now U.S. Fish and Wildlife Service). A second temporary assignment in 1896 led to Howell's position as permanent special assistant.
Howell achieved the position of Senior Biologist in the Division of Wildlife Research, Fish and Wildlife Service (successor agency of the Bureau of Biological Survey), according to "Arthur Holmes Howell Papers, circa 1905-1940, 1967" on the Smithsonian Institution's Libraries and Archives website.

The four-month appointment entailed field work in Montana, Idaho, Washington and Oregon. Howell's second temporary assignment with Bailey began May 1896. At the end of Howell's six-month appointment, the USDA permanentized his employment, according to American biologist and zoologist Viola Shelly Schantz (June 20, 1895-May 26, 1977) in "In Memoriam: Arthur H Howell," published July 1963, in The Auk (vol. 80, issue 3, pages 290-294).
