 President in the Chair. 



Dr. Ajres stated some remarkable facts connected with the 

 recent floods in this State. 



For the last two months, the fishermen who supply the markets 

 of this city with fish have taken in the bay of San Francisco many 

 fresh water fishes, of species generally found in the rivers, not those 

 inhabiting the smaller creeks. These have been caught at all the 

 various points in the bay, at Avliich salt water fishes only have pre- 

 viously been found. It is well known that the surface waters of 

 the bay have been nearly fresh during these floods, and the fishes 

 in question must have followed down and hved this length of time 

 in the fresh surface water. They have not been seen in the bay 

 before this. The following species have been noticed : 



Archoplites interruptus. 



Catostomus occidejitalis. 



Gatostomus labiatus. 



Orthodon mierolepidotus. 



Algansea formosa. 



Lavinia compressa. 



PtychoeJieilus graridis. 



Mylopliarodon robustus. 



Many serpents have also been brought down, and have been cast 

 up in numbers ahve on the beach. Even rattlesnakes have been 

 caught m the nets, it is said. 



In connection with this, Dr. Ayres mentioned, as a curious result 

 of civilization, that immediately in Oakland rattlesnakes have 

 increased much in numbers since the lands have been fenced, and 

 the hogs, which previously destroyed these serpents, thus restricted 

 m their range.
