2 BULLETIK 10 0, UNITED STATES NATIONAL. MUSEUM 



M. Smith, director of the expedition; F. M. Chamberlain, naturalist; 

 Lewis Radcliffe, assistant naturalist; C. E. Wells, ship's clerk; and 

 K. Ito, artist, was duh^ acknowledged. In this connection should 

 also be mentioned the untiring assistance rendered bj Dr. Paul 

 Bartsch, who served as the representative of the United States 

 National Musuem on board the Albatross during part of the cruise. 

 The excellent preparation of the material is due to their efforts. The 

 immense collections were obtained by dredging, seining, trapping, 

 dynamiting the reefs, as well as by the use of submarine light at night 

 and by purchase of market material. The color notes based upon 

 the fresh specimens, in many instances supplemented by color 

 sketches made by Mr. Ito, have been incorporated in the text and 

 are cited with the field number of the tag attached to the specimen. 

 While all the mateiials collected by the United States steamer 

 Albatross from 1907 to 1910 in the Philippines and East Indian 

 region, representative of the above families, form tlie basis of this 

 work, we have also examined the general series of material m the 

 United States National Museum pertaining to the same limits. 

 Many of these fishes early attracted the pioneer voyagers and natm- 

 lists, so that many have long been known to science. It therefore 

 follo'ws that we have very few to report as new. The following are 

 the few new taxonomic units. 



Desinoprenes, nevN^ subgenus, mider Scatophagus. 

 Harpurina, new subgenus, under Hepatus. 

 Hepatus nuhilis, new species. 

 Oyphomyder, new subgenus, under Naso. 

 Siganus pundatissimus, new species. 

 Besides the species represented in the above collections, we have 

 also included all those described or reported from the entire Indo- 

 Pacific region. For these only regional and other important or dis- 

 tributional references are given, besides a condensed account, duly 

 credited. As the hepatids and siganids were not included in Blocker's 

 unfinished Atlas we have given all his important references so far as 

 we could locate them. 



Besides the figures of the few new species are a number ol others 

 portraying the Variation of some of the more strikmg individuals 

 with reference to color designs. These are by Henry W. Fowler. 

 We are mdebted to Earl D. Keid for copymg the data of a number 



of specimens. ■
