None of the fins shows pig- mentation during development (Fig. 3). Ossification At 4,6 mm the premaxilla with four teeth, the maxilla, and the mandible with two teeth are ossified as well as the cleithrum. Ossification of the pre- opercle has begun and two spines may be distinguished on the margin as well as one small spine originating in the middle of the preopercle in line with the 4,6 mm. 6,0 mm.
