Calcaxonian octocorals, Pacific, seamounts
Eleven calcaxonian gorgonians are reported from seamounts in the Northeast Pacific, including eight new records for this region, six of which are described as new species. Twenty-one calcaxonians are now known from the Northeast Pacific (exclusive of Alaska). A table of comparisons is given for all six species of Parastenella and the three eastern Pacific species of Calyptrophora. A neotype is designated for Chrysogorgia fruticosa.

Preliminary analyses indicate that 20 coral taxa were found, and they were almost exclusively located in high relief, ridge areas.
