    Using gross morphological, histological and histochemical approaches, gastric mucosae of three Pteropodids, one Vespertilionid, one Rhinolophid and one Hipposiderid, all from Asia, are described and compared with that of an omnivorous Phyllostomatid. All are also compared with the gastric mucosae of various other American species. There are clear differences between the frugivorous bats of the New World and those of the Old World but the insectivorous species show a fairly great uniformity. This situation is tentatively related to the historical evolution and the dispersal of those animals.

    This paper deals with the snorting voice of the sika deer (Cervus nippon) emitted as a response to the mimic sound, which is made by blowing strongly a thin sheet put between thumbs. The researches were carried out at Akasaka Pass in Iwate Prefecture, Omote-Nikko in Tochigi Prefecture, and the Tanzawa Mountains in Kanagawa Prefecture, from May to October, 1969-1972. In the daytime, without exceptions, the deer ran away with or without snorting voice, responding to the mimic sounds. At night, however, the deer replied by snorting voices from here and there in a wide extent. But their response of snorting voice was restricted to the nights of bright moonlight. It was apparent from the replied snortings that the females were spaced away from each other. They were probably emitted by adult does which were widely dispersed in the calving and lactating season. Accordingly, these snortings should be considered to have a threatening effect against intruders as well as alarming for the group members.

    Food habits of the sika deer Cervus nippon were investigated in Omote-Nikko, Tochigi Prefecture from 1971 to 1973.
    Eighty-two species eaten by the animals were recorded; 57 species of them were trees, 24 species were herbs, and one species was fungus.
    Sasa nipponica was grazed all the year round as most important basic food plant both in quantity and in quality especially in winter when food plants were scarce. Carex sp. was also eaten throughout the year but in small quantity, and barks of Larix leptoleps, Pinus densiflora and Salix bakko also served as winter foods.
    In May, buds and leaves of different plant species appeared successively. Deer grazed and browsed such plants one after another. Thus within a short period, many plants were recorded as deer food.
    From June to August, 51 species were grazed and browsed, with strong preference of leaves and twigs of Hydrangea paniculata, Weigela decola and Stephanandra incisa. Grazing of herbs such as Leucosceptrum japonicum and Eupatrium chinense var. sachalinense was heavier than the browsing of tree leaves. One species of Agaricaceae was also eaten.
    In September and October, leaves of Leucosceptrum japonicum, Eupatrium chinense var. sachalinense, Weigera decora and Clethra barbinervis were abundantly eaten. On the other hand, browsing of Sasa nipponica decreased. The leaves of L. japonicum and E. chinense var. sachalinense withered by the frost were not grazed. The analysis of the stomach contents showed that the acorns of Quercus mongolica var. grosseserrata and the fruits of Malus tshonoskii were also fed in this season.
    In November and December, Sasa nipponica got abundantly grazed again. Most of the food plant species in this season were those commonly found in winter.

    In May, 1973, a two-year old female and three-year old male Japanese deer Cervrts nippon centralis, were captured by boat when swimming on Lake Chuzenji, Nikko, to escape from feral dogs. These were kept at National Breeding Center of Japanese Weasel at Nikko in seminatural confinement of 1.5 ha, from May 9 to June 8 (female) and from May 26 to August 10 (male) . During these periods, preference of food plants were thoroughly investigated by checking the grazing of every plant species in the area. They first concentrated on particular (most preferred) plants, gradually grazing other less preferred species. In total, 46 families, 114 species of plants were eaten until they were allowed to escape.
