126 Director's Annual Report. boats had called there and found shark fishing profitable some years before, but at this time few were seen and no specimens secured. On my return to Honolulu a prelimiuar}^ examination of the material secured brought to light a number of interesting speci-mens. The aid of Dr. C. H. Gilbert, who had kindly offered to assist the author of this monograph in mooted questions of nomen-clature, etc., was accordingly sought. A portion of the colledlion was subsequently forwarded to him. Mr. Albert C. Herre, of Stanford Universit}-, volunteered to help in bringing this list to a completion ; he has written the descriptions of all the new species and has added many notes and observations of value. Dr. Gilbert, in commenting on the colledlion, says {in litt.) that "If the Marcus Island fauna had turned out to be an extension of the Hawaiian fauna we could have sent you a list in a few days. But there are apparently very few Hawaiian species found there, the complec-tion of the fauna being of the South Seas." The numbers given are those of the specimens in the Bishop Museum. A duplicate series will be deposited in the Iceland Stanford Jr. University. The arrangement followed is, so far as possible, that of Jordan and Kvermann in their work on the Fishes of North and Middle America. Color notes were frequently taken from the fresh specimen. In conclusion I wish here to express my indebtedness to Dr. Gilbert and his associates at Iceland Stanford Jr. University, as well as to Mr. Scale of the Bishop Museum staff, for their kind and generous a,ssistance. To Mr. Herre, who shares the authorship of the appendix, I am especially beholden. W. A. B. ANNOTATED LIST OF THE MARCUS ISLAND FISHES. liv Wm. Ai>a.\,s().\ Bkvan' and Alhekt C. Heuuk.
