Figure lO. — Bathymetry of Munidopsis species from the continental slope, Cascadia Basin, and Tufts Plain off Oregon and 



Washington. 



Four types of species distribution patterns 

 emerge when all the stations on Cascadia Basin 

 and Tufts Plain are considered (Figure 11). Two 

 species, M. latirostris and M. bairdii, were found 



30 



at most stations sampled in Cascadia Basin. The 

 most abundant species, M. latirostris, was also 

 the most widespread since it occurred at all but 

 two of the Cascadia Basin stations. It occurred at
