Studies on the Two New Zealand Bats
During a recent investigation of the two New Zealand bats, Mystacina tuberculata Gray and Chalinolobus tuberculatus (Forster), an attempt was made to survey the distribution of these species, and to review the fragmentary knowledge of their ecology and behaviour. A brief account of some of the results of this survey has already been published (Dwyer, 1960) but it is felt that a detailed report of the data obtained may be of worth in providing a basis for future work. The author was unable to make any personal observations on living bats. During the three years ended 1959, numerous trips were made at all seasons to the Tararua and Rimutaka ranges (South Wellington). In addition the following localities were visited: Egmont (April, 1957), Marlborough Sounds (November, 1957), northern Ruahine Range (April, 1958), Kapiti Island (November, 1958) and Waitomo district (June, 1959). At the last named locality some skeletal material of Mystacina was obtained.
