A robust decapod fauna, including ten species in nine genera, has been reco
vered from the Eocene ?Aldwell Formation near Pulali Point, Washington. New
taxa include Portunites macrospinus n. sp., Carpilius occidentalis n. sp.,
Pulalius dunhamorum n. gen. and sp. Pulalius vulgaris (Rathbun, 1926) new
combination has been removed from Zanthopsis McCoy. Palaeopinnixa rathbunae
new name is offered as a replacement name for Pinnixa eocenica Rathbun whi
ch is herein referred to Palaeopinnixa Via. Palaeopinnixa is placed within
the Hexapodidae. This is the first notice of Carpilius Leach in Desmarest i
n the eastern Pacific region. The decapod fauna is typical of those previou
sly reported from deep-water, continental slope settings of the Pacific Nor
thwest with the exception of the occurrence of Carpilius, which has a mainl
y tropical distribution, and Palaeopinnixa which has previously been report
ed primarily from lower-latitude settings.
