455 Yalden Yalden’s Rat Desmomys yaldeni Lavrenchenko, 2003 Dr. Derek William Yalden (b. 1940) is a British zoologist who received his doctorate in 1966 in London. In 2005 he retired from the School of Biological Sciences at the University of Manchester after 40 years’ service. In 1968 he was one of the zoologists on the Great Abbai expedition . He has written many scientific papers and longer works, including History of British Mammals. In 1975 he co-authored, with P. A. Morris, The Lives of Bats. He was the leading author of the “Catalogue of the Mammals of Ethiopia,” published in seven parts in Monitore Zoologico Italiano, which took from 1976 to 1997 to complete and involved five collecting trips to Ethiopia. The rat is endemic to southwest Ethiopia. Yamashina Taiwanese Mole-Shrew Anourosorex yamashinai Kuroda, 1935 Marquis Dr. Yoshimaro Yamashina (1900– 1989) was the second son of Prince Kikumaro Yamashina and developed a keen interest in birds as a child. He was an ornithology graduate at Tokyo University and was awarded his Ph.D. following research on avian cytology, in affiliation with the University of Hokkaido. In 1932, after army service, he built a museum in his backyard to house his collection of bird specimens and books. Wanting to share it with others, he opened it up to the public, and later it became the Yamashina Institute for Ornithology , moved to larger premises and administered under the auspices of the Department for Education. He was also honored in the trinomial of a bird, Chalcophaps indica yamashinai , and received many awards including the Jean Delacour Prize, which some consider the “Nobel Prize in Ornithology.” He was co-author of the Handlist of the Japanese Birds and author of Birds in Japan (1961). In 1981 he described a new species of flightless rail from Okinawa Island. As the mole-shrew’s common name implies, the species is from Taiwan where Orii (q.v.) worked as a collector for Marquis Yamashina during 1932 and 1933. Yepes Yepes’ Long-nosed Armadillo Dasypus yepesi Vizcaíno, 1995 Dr. Jose Yepes (1897–1976) was an Argentinean zoologist. He wrote various articles, most prolifically in the 1930s and 1940s. With Angel Cabrera he co-wrote Mamíferos Sud Americanos (1940) and Catálogo de los mamíferos de América del Sur (1957–1961). The long-nosed armadillo is known from Jujuy and Salta provinces, northwest Argentina.

Yonenaga’s Atlantic Spiny-rat] Professor Dr. Yatiyo Yonenaga-Yassuda is a Brazilian biologist of Japanese descent. She took three degrees at São Paulo University, culminating in a doctorate in genetic biology in 1973. She became an Assistant Professor in the Biology Department of the Biological Science Institute of the University of São Paulo, Brazil, in 1969. She specializes in vertebrate genetics, in particular those of rodents. She has written numerous articles on “the Brazilian fauna of rodents , marsupials, lizards and amphibians undercytogenetical ,molecularandmorphological aspects.” The rat is found in the state of Bahia, eastern Brazil. Yoshiyuki Yoshiyuki’s Myotis Myotis yesoensis Yoshiyuki, 1984 Dr. Mizuko Yoshiyuki is a Japanese zoologist. For many years she worked at the Department of Zoology, National Science Museum, Tokyo, as a Research Fellow and was Professor at the Tokyo University of Agriculture. She also described the Taiwan Big-eared Bat Plecotus taivanus in 1991. She has written a number of papers, such as, with Imaizumi, “Taxonomic Status of the Japanese Otter (Carnivora, Mustelidae ), with a Description of a New Species” (1989). The bat is endemic to Hokkaido, Japan. Young White-winged Vampire Bat Diaemus youngi Jentink, 1893 Dr. Charles Grove Young (1849–1934) was in the Medical Service in British Guiana (now Guyana) from 1873 to 1898. He clearly had an overall interest in natural history, as in 1900 he published “Stalk-eyed Crustacea of British Guiana , West Indies, and Bermuda” and, in three parts in The Ibis between October 1928 and April 1929, “A Contribution to the Ornithology of the Coastland of British Guiana.” He had a relative who was also a keen observer, with whom he co-wrote Some Birds of...
