Abstract
The pomacanthid fish Centropyge shepardi is described from specimens collected on reefs in the Mariana and Ogasawara (Bonin) Islands in the depth range of 10 to 56m.It most closely resembles the wide-ranging Indo-Pacific Centropyge bispinosus, sharing with it similar color, morphometric, and meristic data.It differs in having modally 17 instead of 16 pectoral rays, a slightly instead of strongly rounded caudal fin, and more lightly pig-mented median fins.In life it lacks the wash of blue over the head and median fins and a blue-edged orange-red spot at the pectoral base.
