The material for these investigations mainly originates with collections of my own from the different localities throughout several years. The Serpulides from Faxe are mainly collected in 1910, when the Hydrocorals were worked on.
Besides my own collections I have received for investigation several Serpulides from Mr. Rosenkrantz and Dr. Ødum, to whom I return my hearty thanks.
Material of comparison from foreign localities I have had from Meudon near Paris, from Trimingham in England and from Rügen and Gross Bülten in Northern Germany, and for this I am greatly indebted to Mr. Harald Faber, who has spared no pains in helping me, and to Dr. Voigt, Dessau, who in several ways has stood by me.
