BY DAVID STARR JORDAN AND JAMES ALEXANDER GUNN, JR. 



In 1891, Mr. O. F. Cook presented to the Museum of the Leland 

 Stanford Junior University a valuable collection of fishes which he 

 had obtained on a visit to the Canary Islands. We give below an 

 annotated list of the species contained in this collection with a de- 

 scription of those which are new. The following species seem to be 

 new to science. 



Umbrina valida Jordan and Gunn, No. 10,584, L. S. Jr. U. 



Scorpcena rubelllo Jordan and Gunn, No. 4,291, L. S. Jr. U. 



Scorpcena teneviffea Jordan and Gunn, No. 3,111, L. S. Jr. U. 



Blennius canariensis Jordan and Gunn, No. 4,285, L. S. Jr. U.
