Abstract
Two species of Protodorvillea described from California and Wash- <br /><br />ington have been reexamined and determined to belong to the genus Pettiboneia. <br /><br />Structures originally described as branchiae have been determined to bear internal <br /><br />aciculae and are actually dorsal cirri. The numerous rows of accessory denticles <br /><br />originally noted as specific characters are generic level characters in Pettiboneia. <br /><br />The two species, P. pugettensis and P. dibranchiata, are redescribed and compared <br /><br />with related species of Pettiboneia.
