Hirudisomatid Millipeds 
125 
Remarks — Cook (1904) provided few clues as to this species’ 
identity, but his illustration of the broad telson indicates a hirudisomatid, 
and only one ordinal representative, a hirudisomatid, occurs around 
Seattle and Puget Sound. It must therefore carry Cook’s name.
