Species of the West Indian Leodicidae have been described by Baird (1870), Schmarda (1861), Grube (1856 and 1857), Pourtales (1863-1869), Webster (1884), Mclntosh (1885), Ehlers (1887), Augener (1906), Verrill (1900), and Treadwell (1901, 1911, 1917). Grube and Verrill published no figures, and while the papers by Ehlers and Augener are well illustrated, it is evident that much of their material was not well preserved. Moreover (with the exception of Verrill, who gave no figures), dealing as they did solely with preserved material, they were unable to record the character of the living coloration, often so brilliant in this family. It was, therefore, with especial pleasure that I availed myself of the opportunity offered by the Director of the Department of Marine Biology of the Carnegie Institution of Washington to undertake a systematic study of the family, basing my account on living specimens. With the aid of artists generously provided by the Department I am able to give water-color drawings of the living animals in practically all of the species described, though in a few cases, owing to the too rapid accumulation of material or for other reasons, it was not possible to do this. With the exception of two species (see pages 76 and 125), the descriptions are based on my own collections. I have also studied the collections of the American Museum of Natural History in New York City, of the Museum of Yale University, the Museum of Comparative Zoology at Harvard University, and the United States National Museum in Washington. My own collections were made at the Dry Tortugas and Key West region of Florida, and in Bermuda, Porto Rico, Montego Bay, Jamaica, and Tobago. The locations of the stations where collecting was done are shown by the map on the opposite page.
