Distribution. — Probably widely present through the eastern Pacific, 

 from western Canada south to the Straits of Magellan, including the 

 tropical Pacific. On the eastern coast of the Americas, it has been reported 

 only from the New England states, south to South Carolina. New Zea- 

 land (Augener, 1927, p. 351 ). Intertidal, to 54 fms.

 lin, 1918, p. 177; 1919, p. 260; Berkeley, 1935, p. 770.

 Distribution. — California; Japan. Intertidal, to 65 fms. 



Glycera dibranchiata Ehlers 



Glycera dibranchiata Ehlers, 1868, pp. 670-702, pi. 24, figs. 3-8, 10-28; 



Chamberlin, 1919, p. 350; Treadwell, 1928, p. 473. 

 Rhynchobolus dibranchiatus Webster, 1879, p. 245. 

 Euglycera dibranchiata Webster and Benedict, 1887, p. 723. 



Collection. — Mission Bay, California. One specimen. 



A single, complete individual, 150 mm long, agrees remarkably well 

 with the original description by Ehlers (1868, p. 670). Its occurrence on 

 the Pacific coast is of interest because it has not been reported heretofore 

 outside of the eastern coast of North America. The single specimen was 

 collected by R. L. Morrison from southern California, presumably Mis- 

 sion Bay. More complete data are lacking. 



Distribution. — New England coast, south to Cape Hatteras; south- 

 ern California. Intertidal, to 633 fms.
