ガラパゴスゾウガメ
Rollo Howard Beck (26 August 1870 – 22 November 1950) was an American ornithologist, bird collector for museums, and explorer. Beck's petrel and three taxa of reptiles are named after him, including a subspecies of Galápagos tortoise, "Chelonoidis nigra becki" from Volcán Wolf. A recent paper by Fellers examines all the known taxa named for Beck. Beck was recognized for his extraordinary ability as a field worker by Robert Cushman Murphy as being "in a class by himself," and by University of California at Berkeley professor of zoology Frank Pitelka as ""the" field worker" of his generation.
