Our results underline the role of Indochina as a key area for amphibian diversity and conservation. The analysis of amphibian distribution patterns across Indochina suggests the presence of 14 chorotypes grouped in five major range types. We identify the Northeast and Northwest Uplands of Vietnam, the Northern, Central and Southern Annamites, the Cardamom Mountains, the mountains of Northeast Thailand, Northern Tenasserim and southern Peninsular Thailand as nine major centers of diversity and endemism of Indochinese amphibians. Within the northern mainland portion of Indochina three clusters can be distinguished: (1) northeastern and northwestern uplands of Vietnam and northern Laos (2) Northern, Central, and Southern Annamites, the Bolaven Plateau, and central-south Vietnam lowlands (3) western Indochinese subregions. A cluster analysis of faunal similarity between the subregions shows two major assemblages, divided by the Isthmus of Kra. ![]() Comprising 270 known species, the amphibian fauna of Vietnam is the richest (98 endemics, 36.3%), followed by Thailand with 194 species (29 endemics, 14.9%), Laos with 121 species (13 endemics, 10.7%), and Cambodia with 72 species (6 endemics, 8.3%). In total we record 423 amphibian species belonging to three orders, 11 families and 71 genera 199 species (47%) are endemic to Indochina. We review the distribution of each species across the 23 biogeographic subregions of Indochina, estimate the similarity among the regional faunas and evaluate their species richness and endemism. For each species we provide the following information: scientific name recommended common name in English information on type specimens type locality data on its distribution within Indochina and beyond IUCN conservation status taxonomic comment and the most important references. Amphibian checklists for Laos and Cambodia are published for the first time. We review the literature and our data to assess all recent discoveries and taxonomic changes and compile the first annotated checklist of the amphibian fauna of Indochina since the middle of the 20th century, including updated faunal lists for Vietnam and Thailand. About 60% of the known species were described within the last 20 years. The amphibian fauna of Indochina (including Vietnam, Laos, Cambodia and Thailand) is one of the richest in the world. As this monograph contains mainly references connected with our own work, the reader who wishes to make a survey of lactation should study the references cited in the bibliography, such as COWIE (1961, 1966), COWIE and FOLLEY (1957, 1961), FOLLEY (1952, 1956), JACOB SOHN (1961), LYONS and DIXON (1966), MEITES (1959a, 1961, 1966), MEITES and NICOLL (1966).The Indochinese Peninsula is recognized as one of the key global biodiversity hotspots. JOEL BITMAN, Hormone Physiology Leader of the USDA Agri cultural Research Service at Beltsville, Md., the sponsor of this research. A10-AH-3, and recently with another grant for a further 5-year period, No. Our work in this sphere was made possible by a generous grant from the United States Department of Agriculture, which helped us during the first 5 years of research with Grant No. ![]() This is, in fact, part of a much more extensive research field to which our Department is applying itself at present, viz. The topic is so fascinating that new research students are attracted to it every year, and the circle is growing steadily. ![]() The contents of this monograph "Hypothalamic Control of Lacta tion" are the result of studies by a nine-man team which has worked together for nine years.
