Research on Fishes 81 



a study of a group of marine fishes with world-wide distribu- 

 tion, the crevallies. The literature pertaining to these fishes 

 has first been gone over, compiled, and bound in a brief 

 manuscript review of the group. With this as a basis, it is 

 planned to attack the subject in detail as American Museum 

 material makes this possible. The first short paper of a 

 series it is hoped to submit during the course of this under- 

 taking was published in the Bulletin, December, 1918; a second 

 has been submitted for publication there; a third has been 

 prepared, but is held pending receipt of Peruvian collections 

 which should bear on its subject matter. A note on a rare 

 crevally from Bermuda has just been published in Copeia. 



Whereas it has been possible to give such work priority, 

 collections must in fairness be worked up as they are received. 

 Two papers describing new South American fresh-water fishes, 

 sent here by that institution, have been submitted to the Museu 

 Paulista, Sao Paulo, Brazil, for publication in English and 

 Portuguese, and work on extensive collections of Bermuda 

 and Turk's Island fishes is in progress. The more important 

 papers on fishes published by members of the department 

 during 1919 are "Six new fishes from Northwestern Canada," 

 by Francis Harper and J. T. Nichols (in the American 

 Museum Bulletin) ; "On Caranx guara from Bermuda," J. T. 

 Nichols (in Copeia) ; and the following three titles by E. W. 

 Gudger: "The Myth of the Ship-holder" (Annals and Maga- 

 zine of Natural History) ; "The Ovary of the Gaff-topsail Cat- 

 fish; its Structure and Function" (published by the Carnegie 

 Institution of Washington) ; "On the Use of the Sucking Fish 

 for Catching Fish and Turtles" (American Naturalist).
