2 BULLETIN 100, UNITED STATES NATIONAL MUSEUM 



The numbers of the specimens examined are, unless otherwise 

 specified, those originally designated by the Albatross expedition. 

 Specimens so numbered are deposited in the United States National 

 Museum, but have not yet been given catalogue numbers. This 

 also applies to specimens listed in Bulletin 100, volumes 7, 8, 10, 

 and 11. All figures in this volume were drawn by the author. 



In naming type localities, where more than one locality is given 

 the first named is to be considered as the type locality.
