We also include an examination ©f all the installed representatives 

 in the general series of fishes in the United States National Museum 

 pertaining to the species embraced by this report, along with the 

 types, and the material in the Academy of Natural Sciences has 

 been studied and listed in the same manner. 



From these studies many valuable deductions and corrected deter- 

 minations of materials have resulted. 



The figures illustrating this report were prepared under our direc- 

 tion with the assistance of George MacReynolds. 



In explanation of the method used in describing species we might 

 say that the depth of the body refers to its greatest depth not includ- 

 ing vertical fins and the number of times it may be computed in the 

 body length to the base of the caudal fin. The head is measured 

 likewise with its breadth referring to its length ; also the snout, eye, 

 maxillary, and interorbital. Wlien the mandible or lower jaw pro- 

 trudes in front, the snout is mentioned with the number of times it 

 is contained in the head, followed by the statement from snout tip, 

 thus showing that the protruding portion of the lower jaw is not 

 included in this measurement. In the same wa.y the dimensions are 

 intended to follow through the descriptions or until it is indicated 

 as the total head length. 



As the lateral line is frequently incomplete or interrupted, the sec- 

 tions are always indicated, thus a plus sign indicates an interruption 

 (of either scales or pores), or of those on the caudal base. In cases 

 where the lateral line is angularly bent on the side of the tail the 

 interruption of the count is indicated by a comma. 



We are indebted to Earl D. Keid, of the Division of Fishes, for 

 assistance in handling the large series of specimens.
