Abstract: Dissections were made of the larynges of 14 species of the cat family, with representative specimens from all genera. It was found that the vocal folds of the larynx of genus Panthera (with the exception of the snow leopard) form the basic structure of a sound generator well- designed to produce a high acoustical energy. Combined with an efficient sound radiator (vocal tract) that can be adjusted in length, a Panthera can use its vocal instrument literally to blow its own horn with a 'roar'. Also, it is proposed that laryngeal morphology can be used as an anatomical character in mammalian taxonomy.

Abstract: Zoolites of the Felidae family are known from the Upper Eocene Lower Pliocene in Eurasia, Africa, and North America. Two sub-families are know to inhabit the territory of the USSR and adjacent territories: the extinct sabre-toothed Felidae species Machairodontia and now existing Felidae species. In the USSR the extinct Felidae species were found to exist in Upper Miocene, Upper and Middle Pliocene, and Pleistocene. In Eurasia panthers has been know since early Pliocene. Three species were found in Uzbekistan – the extinct cave lion Felidae sd†l…†… (Goldfuss, 1810), and now existing P…nth†a… tigris, P…nth†a… pardus. The ancient finds and modern habitats are briefly described. Genus Uncia is represented by one species snow leopard or irbis. Probably it appeared in later Pliocene or Pleistocene in the mountain of Central Asia. In Uzbekistan, remains of snow leopard were found in the Samarqand region in the layer of Upper Pleistocene or Holocene. Probably it moved into the area in Pleistocene or the period of glacier removal in the Western Tien Shan mountains, Turkestan, Zeravshan, and Hissar ridges.
