Discussion Rather eroded specimens the best of which is figured ( Fig. 44f View Fig ). It bears the main features found in the genus in respect to otolith shape and proportions and also the specific shape of the ventral furrow but differs from the known extant species in the large sulcus (OL:OH = 1.7). It probably represents a fossil species close to G. oceanicus ( Fig. 44d View Fig ) but more and better preserved specimens are required for a reliable definition.
