After completing that portion of the manuscript on the marine fishes 

 of the west coast of South America which deals with the Apodal fishes, 

 it seems desirable at this time to describe the new forms. These were 

 collected either by the senior author in tide pools or under an electric 

 light swung at the ship's gangway at night while at anchor, or in dredge 

 hauls from the ship or the small dredging launch, during the 1938 cruise 

 of the Velero III, under the command of Captain Allan Hancock. The 

 major part of the collecting was done at the Galapagos Islands and along 

 the coasts of Colombia, Ecuador, and Peru ; but a few species were ob- 

 tained farther north along the Central American coast, especially at Cocos 

 Island, Costa Rica. The authors are also including a new genus and two 

 new species from the Hancock Pacific Expeditions' material in the United 

 States National Museum, collected by Dr. Waldo L. Schmitt on the 1935 

 expedition. 



In the list of specimens at the beginning of each description AHF 

 refers to catalogue numbers in the ichthyological collections of the Allan 

 Hancock Foundation. All holotypes save two are in the Allan Hancock 

 Foundation. Where there is more than one paratype, one or more para- 

 types are to be deposited in the Natural History Museum of Stanford 

 University, where the work upon these fishes was done.
