WoRMS source details
The marine chaetopods of the Dillon Beach areas, in Marin and Sonoma counties, are much like those from other parts of northern and southern California. The 101 species, reported below, were collected during the summers of 1935 and 1941. Seven species and one subspecies are believed new to science, and some others are first records either from California or from the areas indicated. The collections are deposited in the Allan Hancock Foundation of The University of Southern California; a duplicate set is at the University of California.
