Gill opening a nearly vertical slit slightly below middle of body, its upper end slightly below upper edge of pectoral-fin base, thus not completely enclosing the pectoral fin (the original illustration in Myers and Wade, 1941, pl. 7, reproduced in slightly modified form here as Figure 1, was wrong in this regard); interbranchial nearly equal to gill opening.</paragraph>
