﻿SIPUNCULID WORMS OF CALIFORNIA — ^FISHER 395 



testiiial spiral, which has 30 single coils and is anchored posteriorly 

 by the spindle muscle. The recliini is hont forward and anchored to 

 the dorsal body wail nearly as far as the coecuni by a mesentery, 

 along the free edge of which runs the inconspicuous spindle muscle. 

 There are no fixing muscles and the ^^^ng muscles are small. 



When filled with sex products the two nephridia are very large and 

 each has a long anterior lobe. They open at a conspicuous distance 

 in front of the anus, and the neplirostome has two semicircular lips. 



I am unable to find any contractile vessel. 



Type. — In the Museum of Comparative Zoology. 



Type locality. — Balboa, Newport Bay, Orange County, Calif. 



Distribution. — Monterey Bay to Gulf of California. 



Specimens examined. — As follows: 



Pacific Grove, Monterey Bay, Calif., 1911, W. F. Thompson, 10 specimens. 



Newport Bay, Calif., numerous specimens collected at Balboa (mud flats) and 

 Corona del Mar (beach), August 1929, February 1930 and 1933, by G. E. 

 MacGinitie. 



Laguna Beach, Calif., September 1917, on "eel grass," 2 paratypes. 



San Lucas Cove, south of Santa Rosalia, on gulf coast of Baja California, "com- 

 mensal in tubes of Cerianthus," March 24, 1941, E. F. Ricketts, 19 specimens. 



Remarks. — Professor MacGinitie's specimens were found along the 

 outside of the tubes of Mesochaetopterus sp.; those collected by Mr. 

 Ricketts were commensal within the tubes of Cerianthus. The dis- 

 sected specimen, with nephridia distended bj^ spenn, was collected in 

 August 1929. Golfingia misakiana lives under seaweeds covering a 

 tufaceous sandstone between tide marks. Misaki, Japan (Ikeda, 1904,
