In February 10, 1974, a strange hawkfish, 47.0 mm in standard length, 56.5 mm in total length, referred to <I>Oxycirrhites typus</I> Bleeker, which has not previously been reported from Japan was taken at a depth of 40 meter on the coast of Izu, Shizuoka Prefecture.The fish is characterized by having peculiar pectoral fin, the lower several rays of which are unbranched and thickened, elongated snout, well-serrated preopercle and the slender body with reddish fretwork.The specimen examined here agrees with Bleeker's holotype and other specimens of the species obtained from some tropical seas of the Indo-Pacific except for larger eye (4.8 in head length for the present specimen, 5.5 to 6.4 for others), fewer serrations of the preopercle (8 instead of 11 to 23), and moderately forked caudal fin (slightly forked fin in the holotype).
