Quatenary vertebrates have been rarely known from north of Kanto in Japan. Shiriya local fauna, that was first reported in 1957 (NAKAJIMA & KUWANO), has been the most important one in northern Japan. Although a faunal list of the Shiriya local fauna was provided by HASEGAWA (1972), the fauna itself has not been described nor illustrated except for the rodents (KOWALSKI & HASEGAWA, 1976 : 7 spp.) and a canine of the Japanese monkey (IWAMOTO & HASEGAWA, 1972). Additional survey and fossil collection were done at Shiriya area as a part of natural history research conducted by National Science Museum in 1987,and many newly known species were added from the area. Faunal list including previous collection is provided in Table 1. Although complete descriptions of the fauna were not able to be provided in the present paper, most of the faunal elements are illustrated and commented with distinctive characters from related species, especially in small animals. Shiriya local fauna can be divided into two assemblages : 1. Panthera-Pinnipedia assemblage that is related with the upper terrace (about 70 m above s.l.) and is characterized by abundance of Panthera and several species of pinnipeds and by rarity of small mammals, amphibians, ect.; 2. Canis-Mancalla assemblage that is related with the lower terrace (about 30 m above s.l.) and is characterized by the presence of Canis lupus, Ursus arctos, Paleoloxodon naumanni, Mancalla sp., and by abundance of small mammals, amphibians, and terrestrial and marine gastropods. Both of them may be correlated faunally with the Upper Kuzuu fauna in Kanto area.
