In a very interesting collection of annelids from Laguna Beach
transmitted to me for study by Prof. Hilton, the apparently previously
undescribed forms listed below are represented. As a comprehensive
report on the annelids of the region to follow further explorations and
collecting is in contemplation, I am giving here only such preliminary
accounts of the new forms as are thought sufficient for their
identification in the local fauna. The types of all these species are
in the Museum of Comparative Zoology at Cambridge.
