cies from the King Salmon or Chinook Salmon, which now runs 

 up from the sea to spawn in the same region. "We may therefore 

 provisionally record it as Oncorhynchus tschawytscha. These

 season. It is interesting to know that the anadromous habits of 

 these fishes are of such long standing.

 Quaternary? Near Fossil Lake, Oregon. 



Similar remains of fragments of jaws, teeth, and vertebrae 

 were obtained from diatomaceous deposits on Lost Eiver, Oregon, 

 and sent to the University of California by Mr. Selden Ogle of 

 Klamath Falls. 



Family ELOPID.F. 

 Genus Calamopleurus Agassiz. 

 Calamopleurus cylindricus (Agassiz). 



A specimen of this species was found in a long club-shaped 

 concretion about a foot and a half in length (48 cent.) from the 

 interior of the state of Ceara in Brazil. This was presented to 

 Dr. John Branner by Dr. Paulo Pessoa of Bio de Janeiro, and is 

 now in the Museum of Stanford University. On breaking the 

 concretion lengthwise, a fine specimen of this species was dis- 

 closed. We here present the photograph of this specimen.
