«Pecten latiauritus var. fucicolus Dall.
With the last, and living on fuci, south to Cape St. Lucas.
Shell moderately compressed, smooth, concentric, sculpture obsolete; ribs low, rounded, wide, entire; hinge-line shorter than in the type, and without any sinus between the posterior ears and the disk. Alt. 30, lat. 31 mm. This form lives attached by the byssus to the giant kelp of the Californian coast, and the absence of shock, due to the floating situs, is probably correlated with the obsolescence of the ribs and posterior sinus. Intergradations with the type are not at all rare.» WILLIAM HEALEY DALL, 1898
