* Dr. Leonard Stejneger, in the 'Proceedings of the U.S. National Museum’ (vol. v. p. 31), has drawn attention to the fact that previously to Boie having selected the Hirundo urbica of Linnaeus as the type of his genus Chelidon. Thomas Forster had already restricted the same species to Hirundo, and had proposed the name ( helidon for the Common Swallow and its allios. Thus Hirundo ought to bo kept for the Martins, and Chelidon used for the Swallows, reversing the established custom of ornithologists for three quarters of a century. This conclusion of Dr. Stejneger has been adopted by the Committee of the American Ornithologists’ Union, and Chelidon is now in general use for the Barn-Swallows of the New World. In the ‘ Catalogue of Birds’ (vol. x. p. 85) we did not follow Dr. Stejneger‘s conclusions, as wo did not agree that Forster's nominal list of British birds, which gave not a single character or description, ought to supersede the more useful and intelligible work of Boie. A still moro potent reason for not adopting such a wholesale change in nomenclature seemed to be that ornithologists in every country had become accustomed to (he names of Hirundo for the Swallows, and Chelidon for the Martins, and it was a pity to reverse them. The same reasoning has induced us to observe the old-fashioned nomenclature in the present ‘ Monograph.' Moreover in 1889. Dr. Reichenow pointed out that Hirundo rustica had already been fixed as the type of Hirundo by Schaeffer in his ‘Elementa Ornithologica, Genus 100,' and that, in any ease, Forster's genus Chelidon must be a synonym of Hirundo, Sehaeffer. Dr. Reichenow therefore proposed the name Chelidonaria for the House-Martins. and by those who make up their mind to depart from the old-fashioned nomenclature the name Chelidonaria may be employed for the following species:—1. Chelidonaria urbica : 2. C. cashmiriensis ; 3. C. dasypus. : 4. C. lagopus. : 5. C. albigena ; 6. C. nipalensis.
