GENERIC NAMES APPLIED TO BIRDS DURING THE YEARS 1916 TO 1922, INCLUSIVE, WITH ADDITIONS TO WATERHOUSE'S "INDEX GENERUM AVIUM" By Charles W. Richmond Associate Curator, Division of Birds, United States National Museum This is the fourth list ' of generic names of birds compiled by me to serve as supplements to Waterhouse's ''Index Generum Avium." It is not as extensive as the previous Usts, owing to several circum-stances, chief of which is that the literature has been fairly well searched by this time and further omissions from Waterhouse are not easy to find. There are about 435 names listed beyond, of which 378 were pro-posed during the period of 1916 to 1922; the remainder consist for the most part of names hitherto overlooked, a majority of them brought to light through the researches of Messrs. Mathews and Ire-dale. As in the previous supplement, the derivation of names is added when supplied by the original author. I am indebted to several friends for calling attention to certain names that had been missed: Thomas E. Penard furnished the ref-erence to Bruhru, Dr. Herbert Friedmann that to Demelioteucus, Dr. A. Wetmore that to Fontinalis, and E. C. Stuart Baker gave me a clue to the origin of Cursonia, while K. L. Skinner furnished me with a copy of the paper in which the last name was published. Dr. Nagamichi Kuroda kindly sent references to the new names in Momiyama's ''Birds of Micronesia," a work that was until recently inaccessible to me. In the third supplement there were some omissions of page references, and certain errors have been since discovered, all of which may be conveniently mentioned or corrected here. •The earlier lists were as follows: " List of generic terms proposed for birds during the years 1890 to 1900 inclusive, to which are added names omitted by Waterhouse in his ' Index Oenerum .\vium ' " (Proc.
