'Entopterygoid' type' 3: (Ectopterygoid of Tilak 1964.) Rudimentary splint-like, sesamoid bone between the two anterior sharp processes of the metaptery- goid; metapterygoid and 'entopterygoid' are connected by a short ligament (Fig. 2C). The 'entopterygoid' type 3 is connected by connective tissue and Hgaments to me- tapterygoid, autopalatine, and lateral ethmoid (, Eutropiichthys). 'Entopterygoid' type 4: Small, flat, slightly square sesamoid bone found anterior to the metapterygoid and medial to the autopalatine. This type of 'entoptery- goid' is linked by ligaments (Fig. 2D) to the metapterygoid, vomer, autopalatine, and lateral ethmoid (, Heptapterus, Rhamdia, and Noturus). 'Entopterygoid' type 5: (Mesopterygoid of Regan 1911, Gosline 1975, ec- topterygoid of Azpelicueta et al. 1981.) Small, thick, crescentic or triangular, sesamoid bone posterior to the 'ectopterygoid' type 1 (see below) and medial to the autopalatine. It is linked by connective tissue and ligaments (Fig. 2E) to the metapterygoid and lateral ethmoid, and by an indirect ligamentous Hnk to the autopalatine through the 'ectop- terygoid' type 1 (, Parapimelodus)..
