A Rare Fish From Lacuna Beach 
A photograph of this fish was sent to Prof. Cjilbert to whom we 
are indebted for the identification. The specimen was caught on 
a hook and line not far from the laboratory. It was brought in by 
Prof. A. M. Bean. No one in Laguna had e\er seen anything like 
it and no one would \enture an opinion as to what it was.
