The Beaked Whales of the Family Ziphiidae: An Account of the Beaked Whales of the Family Ziphiidae in the Collection of the United States Museum...

A scientific publication written in the early 20th century. This work serves as a bulletin from the United States National Museum, presenting detailed accounts and descriptions of the beaked whale species in their collections, as well as comparisons with specimens from other American museums. The book aims to enhance the understanding of cetacean taxonomy, especially focusing on the rare beaked whales within the Ziphiidae family. The opening of the book introduces readers to the family Ziphiidae, highlighting the rarity of beaked whales compared to other cetaceans. True explains that while there are only about one hundred recorded specimens from three genera—Mesoplodon, Ziphius, and Berardius—his work encompasses descriptions of skulls and skeletons found in the U.S. National Museum. He discusses significant findings that have expanded knowledge on the geographical range of these whales, particularly pertaining to discoveries in the North Pacific. The introduction sets the stage for a meticulous exploration of the anatomical specifics and the careful classification of these elusive marine mammals, emphasizing True's aim to document valuable specimens and contribute to zoological literature.
