---|---|---|
B. Schaeffer 1955 | Fusiform, moderately deep-bodied fishes attaining a length of about 60 mm., and differing from other members of the family Perleididae in the following combination of characters: Skull short anteroposteriorly and relatively deep, nearly one-fifth of total body length. External skull bones thin and without ornamentation. Rostrum sloping, rather than blunt as in Perleidus and Meridensia. Postrostral bone wide ventrally, narrow where it meets the frontals. Nasal bones forming anterior border of orbit, wider dorsally than ventrally. Paired rostrals and dentigerous premaxillaries apparently present. Frontals about twice the length of the rectangular parietals. Dermopterotic narrow and elongated. Suprascapulars separated. Maxillary very narrow anteriorly, expanded posteriorly, with a rounded posterior border. Suspensorium vertical. Wedge-shaped suborbital (or supraspiracular) and dermohyal (or antopercular) present. Preopercular with infraorbital process. Opercular slightly smaller than subopercular. Branchiostegals present. Mandible tapering towards symphysis. Marginal teeth on premaxillary, maxillary, and dentary conical and pointed. Teeth on prearticular stout and blunt as in Perleidus madagascariensis. Supracleithrum and cleithrum typical for family and without ornamentation. Postcleithra apparently absent. |
