molluscs. The bent-nosed clams, Macoma nasuta(Conrad, 1837) of
Yaquina Bay, Lincoln County, Oregon are commonly infected with a new

described and it has been compared to the other three species...
The life cycle of a monogenean, Diclidophora sp., was studied
with special attention to the time required for developmental stages
to occur. Eggs are produced by adult worms at the rate of one every
13.5 minutes and require 32 days to hatch when incubated at 12.5°C
and 30.9‰ salinity. Rate...
