NOTES ON SOME BARNACLES FROM THE GULF OF 



CALIFORNIA 



By Doha Priaulx Henry 



The collection of Cirripedia made by Steinbeck and Ricketts (1941) 

 lias added considerably to our knowledge of the barnacles of the 

 Gulf of California. Although most of the barnacles in the collec- 

 tion were identified by Ira E. Cornwall, of the Hopkins Marine 

 Station, Pacific Grove, Calif., nine lots of their material were ex- 

 amined by the author. Five species or subspecies, one new, were 

 represented in the nine lots; these are starred in the list below. Fif- 

 teen different barnacles have been reported so far from the Gulf of 

 California (see Pilsbry, 1907 and 1916; Steinbeck and Ricketts. 1941; 

 and Henry, 1941) : 



*Balanus amphitrite inexpectatus Pilsbry. 



Balanus concavus Bronn. 1 



Balanus improvisus Darwin. 



Balanus tintinnabulnm californicus Pilsbry. 



*Balanu8 tintirmaiuhim peninsularis PiLsbry. 



*Balan\us trigonus D;irwin. 



Tctraclita squamosa (Bruguiere). 2 



Tetraclita squamosa stalactifera (Lamarck). 



*Tetraclita squamosa stalactifera forma conftnis Pilsbry. 



*CheloniMa patula (Ranzani), new subspecies described herein (p. 370). 



5 Reported by Steinbeck and Ricketts (1941). Probably should be subspecies paciflcu* 

 Pilsbry. 



2 Provisionally identified as subspecies ruiescens Darwin (Steinbeck and Ricketts, 1941),
