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 Ere-
at irregular intervals, usually five to ten times a year

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 Pyc-nonotus rufocaudatus Eyton, 1845.
Use of raptor chemical monitoring data to assess effectiveness of EU chemical management measures; the impact of pooling liver samples on power to detect change in contaminant concentrations at country scale
Derivation of indicators for assessing the quality of biota samples and their suitability for environmental monitoring studies

An appropriate specimen (NMW 6379) in Vienna is duly designated.

Hypotheses of iora phylogeny are reviewed up to date, and the history of the generic name investigated. Interactions between A. nigrolutea and A. tiphia are examined and reasons presented for treating them as separate species. The allowability of a widely disjunct distribution in subspecies A. tiphia deignani Hall, 1957 is queried, and its range narrowed substantially, forcing a re-designation of Indian popula-tions. Additional, small systematic and distributional issues bearing on other Aegithina species are noticed.

It summa-rizes the conservation status of all megapode taxa and indicates the needs of those species under threat. The Action Plan was intended to be a stimulus for conservation orientated studies and to gen-erate funds more easily. An overview is given of studies (1990- present) in which these threatened taxa were involved. The status of these and other taxa are reassessed according to the finalized IUCN threat categories (which supercede the Mace-Lande threat categories originally used in the Action Plan) as a preparation for the megapode action plan 2000- 2004.

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. gated all the names that we found in synonymy, and each such name is listed in our type table, and has been explored to see what was known about the types. A list of acronyms appears before the list of References. Published type catalogues and data provided as part of the original description have remained our main sources, but an increasing community of interested museum curators and collection managers is providing a growing amount of help that is very welcome. In our personal searches for types, which one cannot safely describe as exhaustive, even for the few museums that we have visited, we have been privileged to be able to access and examine type material, as detailed under Acknowledgements. It should not be assumed however that we have re-examined any particular type. We have examined some where we had a particular reason to do so. No significant review of the family or of specific genera has been published since . In this family list we have 19 names of Bonaparte (1850, 1854) of which 16 are from his Conspectus Generum Avium (1850). Bonaparte's system was essentially to number his recognised genera throughout the work, and under each to number the species from one upwards. His generic headings and his chosen specific epithets were in bold type. In our columns we seek to show all original names as they were given in full; in the case of the names from Bonaparte (1850) this is not easy because unless you understand his system and his use of bold type he appears to use other names. More explanatory details are therefore footnoted below. 1 In the following table the spellings Ixus and Ixos whether as generic names or as parts thereof are rendered as they were used. The authors doing so considered their spellings to be correct. They are not therefore marked "[sic]" which signals a lapsus in the spelling. Blyth 1845 ZSI ? 1.

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.

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.
