Abstract
Two new species of the tropical Indo-Pacific gobiid genus Silhouettea, S. evanida and S. hoesei, are described from Darwin and Queensland, and the Cobourg Peninsula, N.T., respectively. S. evanida occurs in pools on intertidal sand flats along beaches and sandy creek mouths, and S. hoesei more sublittorally at 5-6 m on silty sand. A key to western Pacific and Australian species is included.
