Two nesting grounds of the Moluccan Megapode, Eulipoa wallacei (G.R. Gray, 1860) located on the islands of Haruku and Halmahera, Indonesia, are described. Together they provide nesting opportunities for more than half of the estimated world population of this endangered megapode. Further information is given on six additional nesting grounds. Data are presented on size and origin of the megapode populations using these sites, egg-laying season, behaviour, and measurements of birds and eggs in relation to their breeding strategy of using solar heat for the incubation of their eggs. |

Hypotheses of family phylogeny are summarized up to date, and amendments made to the treatment by Delacour (1960) of Chloropsis and Irena in Peters’s Check-list of Birds of the World (Mayr & Greenway, 1960), at and below species level. Revision of species-limits within C. cochinchinensis (Gmelin, 1789) and C. aurifrons (Temminck, 1829) as defined in Delacour (1960) restores three ultra-taxa to species rank, boosting the global list of leafbird species to 11. Certain range and nomenclatural issues are resolved, including re-designation of the type locality of Turdus cochinchinensis, type species of Chloropsis. A new subspecies name is introduced as an outcome. |

A list is provided of the 165 names applied to identifiable Asian forms of species of lark (family Alaudidae). This list summarises our collective knowledge on the whereabouts of types for these names; where our information does not include reliable data we provide notes relating to the deficit and to stimulate others to send us additional data or to suggest sources of information. In two appendices we deal with certain old names that we judge to be indeterminate and we designate a lectotype for Eremophila sibirica (Swinhoe, 1871b). |

Among megapodes, several incubation stategies can be recognized. Eggs are incubated by heat generated from microbial decomposition, volcanism, or the sun. For a long time, controversy has existed whether these strategies represent primitive traits, inherited from reptilian ancestors, or have evolved from the 'regular' way of incubation in birds. In this paper these strategies are interpreted by superimposing them on the most recent phylogenetic hypotheses regarding the inter- and intrafamilial relationships of megapodes. We conclude that similarities shared with reptiles and kiwis are due to convergence. Arguments are put forward that mound-building represents the plesiomorphic condition in megapodes and that burrow-nesting has been derived from it.... |

A list of about 370 names applied to Asian forms of species of bulbul (family Pycnonotidae) is presented. This list provides information on the whereabouts of a type; where our information does not include reliable data we provide notes to explain the deficit and to stimulate others to offer additional data or sources of information. A lectotypes is designated for P[ycnonotus]. Yourdini [sic] “(Homb. & Jacq.)” G.R. Gray, 1847. Comments are also made on previous lectotype designations for Hypsipetes rufigularis Sharpe, 1877, and Criniger simplex Wallace, 1862, and on the need to designate one for Pycnonotus rufocaudatus Eyton, 1845. |
