In Teraponidae :

All the Indo-Pacific species known, pertaining to the families 

 studied in this report, are included. Frequently some are only known 

 from the original description, or perhaps a subsequent examination, 

 or figure of the type. Others may be well established species but not 

 represented in our collections. In all such cases both descriptions 

 and figures are utilized in framing the descriptions for this report, 

 as well as duly credited. 



I have also included an examination of the installed materials of 

 the present families in the general series of fishes in the United 

 States National Museum, also such type specimens as may be in- 

 volved. Similar materials in the Academy of Natural Sciences of 

 Philadelphia are included in the same way. 



In securing the services of Mr. Richard Blossom Farley for pre- 

 paring the illustrations I feel fortunate in being able to present 

 accurate and artistic figures. I am indebted to Mr. Barton A. Bean, 

 of the Division of Fishes, United States National Museum, for 

 supplying some items of data from the original records of the 

 expedition.
