25. Gobius sagittula (Giinther). 



Two large specimens, each six to eight inches long, 

 besides one very young example, corresponding to the 

 form called Gobius longicauda of Jenkins & Evermann. 

 As Dr. Gilbert has noticed, this is the adult form of the 

 species called by Dr. Giinther Euctenogobius sagittzda, 

 of which specimens were found by us at Mazatlan. 



The species is very similar to Gobius oceanicus of the 

 Atlantic.
