In 1937 Vanderbilt chartered the schooner Cressida to cruise the South Pacific on a scientific expedition to collect fish specimens under the auspices of the Academy of Natural Sciences of Philadelphia. On the cruise Mr. and Mrs. Vanderbilt were accompanied by Mr. and Mrs. Samuel B. Jones III as guests. William B. Gray was in charge of fishing activities.[2] With Ronald W. Smith as the expedition's zoologist, the expedition collected about 10,000 individual specimens, excluding a great many larval and immature forms. The 10,000 fish specimens represented 434 (alleged) species and 210 (alleged) genera. The expedition discovered 22 allegedly new species with 5 allegedly new genera[3] (although revisions have been made because of molecular phylogenetics). For example, Fowler's Machaerenchelys vanderbilti has been rejected in favor of Leiuranus semicintus,[4] Acanthapogon vanderbilti has been rejected in favor of Gymnapogon vanderbilti,[5] and Ophioblennius vanderbilti has been rejected in favor of Cirripectes vanderbilti.[6]
