INTRODUCTION. 



The collections represented by material included in the following 

 report were made by the United States Bureau of Fisheries steamer 

 Albatross. During several years the Philippine Expedition made 

 collectioiis covering the waters of the Archipelago and the sun-ound- 

 ing waters of the China Sea and Pacific Ocean. In addition, collec- 

 tions were made in the region to the southward about Borneo, Cele- 

 bes, and the larger East Indies. A part of this southern area is simi- 

 lar to that uicluded in Millett's material, but his was almost entirely 

 from comparatively shallow water, while our material has been 

 largely from much deeper water. The Challenger did some dredghig 

 in the Philippme Archipelago, one station in 95 fathoms (174 meters) 

 off Cebu, being thoroughly worked by Brady and referred to by oth- 

 ers. With these exceptions there are few records for the recent 

 material of the region. As a result, there are many interesting rec- 

 ords and undescribed species. 



A number of years have now been in part given to this report on the 

 Philippine collections. As the collections include nearly 600 dredg- 

 ing stations, besides shallow-water material, the mechanical work, 

 involving as it has the handling and sorting of many thousands of 

 specimens, has been very time-consuming and laborious. The 

 mounted material includes several thousand slides, includmg many 

 thousands of actual specimens. These are m the collection of the 

 United States National Museum. 



The collections probably represent more completely the area cov- 

 ered than any similar collections for a region of equal size. The 

 tropical character of much of the shallow-water material makes it 

 very interesting from various points of view. 



In the study of the collection it has been the purpose to give the 

 distribution of such species in the region, and the tables give the 

 data for these stations. In this way much detailed mformation is 

 available for the causes affecting distribution of vanous genera and 

 species. Something is given of the variation where this occurs, and 

 in some cases changes m nomenclature are discussed where neces-
