[The Netherlands], Limosa, 1950. 8vo (23.2 x 15.6 cm). Title page, 280 pp., 21 full colour plates. Contemporary black grained leatherette over marbled boards. Spine with gilt bands and title

There are two editions of both titles, but this is the definite edition. There is an index to the first title on pp. 157-158, and the second title continues on p. 159, with an index on pp. 279-280. The first editions were published two years earlier, by the Plantentuin in Buitenzorg, Java. ADDED: two separate, printed indexes, for both titles each, which includes the bird names in English and Indonesian; and a similar index to another work by Hoogerwerf, viz. Een bijdrage tot de oölogie van het eiland Java. These indexes were published by Kebun Raya Indonesia (new name for the Plantentuin). The illustrations by Goesti Abdoel Kadir are excellent and the text contains a wealth of information. A very good, clean set. Much rarer than the 1949 edition and in a fine binding.
