DEFINITIONS

VANELLUS
(Charadriidae; Ϯ Northern Lapwing V. vanellus) Med. L. vanellus  lapwing  < dim. L. vannus  winnowing fan (in allusion to the broad wings and floppy flight); "Vanellus. Genus 71.  ...  **1. LE VANNEAU.  ... VANELLUS." (Brisson 1760): based on "Vanellus", "Capella", and "Caprea" of Gessner 1555, and many other authors, and Tringa Vanellus Linnaeus, 1758; "Vanellus Brisson, Orn., 1760, 1, p. 48; 5, p. 94. Type, by tautonymy, Vanellus Brisson = Tringa vanellus Linné." (Peters 1934, II, 235).  The Northern Lapwing appears the most aberrant member of the genus; it has been suggested that Hoplopterus be resurrected for all the other species presently included in Vanellus.   
Var. Canellus, Cranellus.

• "Zosterops minor gregaria subsp. nova.  ...  Von mir gregaria benannt, da die Art viel geselliger ist als novaeguineae oder fuscicapilla; ich fand kleinere und größere Trupps häufig auf Waldlichtungen, in alten Eingeborenenpflanzungen und an Waldränden." (Mayr 1933) (subsp. Zosterops chrysolaemus).
