The brain of Photoblepharon palpebratus steinitzi (Pisces, Teleostei, Anomalopidae).
The external morphology of the brain of Photoblepharon palpebratus steinitzi is typically teleostean in character, and recalls that of the brain of Holocentrus, described by Meader (1934). The encephalization index is very high and near those of Holocentridae, which belong to the same order Beryciformes. The brain organization, studied from the relative volumes of different brain parts, is near that of Holocentridae and Labridae and shows that microsomy (small olfactory bulbs) and the great extension of the cerebellum, visible in external morphology, are good criteria of the peculiarities of the brain of Photoblepharon, which shows no apparent structure in connexion with the light organ.
