The opercular spine is blunt and poorly ossified and distinguishes the species from E. occidentalis, E. trewavosae, E. pectinifer, E. rohiistus, E. lenimen, and E. crassicaudus, which have pungent oper- Y12yc cular spines. Unlike remaining congeners, E. telescopus possesses 11 + 14 vertebrae. Description. Meristic data presented in Table 1; regression data for morphometric traits presented in Table 2. Body thickset, shortened; anterodorsal profile slightly convex, rising most steeply from tip of snout to interorbital region; body moderate to deep, ^ SL; caudal peduncle short, SL. Head moderate to deep, height SL; length SL; snout blunt; angle of gape moderate to large; lower jaw equalling or protruding slightly beyond upper jaw. Maxilla rarely exceed- ing %-% eye length, posterior margin of maxilla broad, posteriormost point near ventral surface of bone; maxillae of large specimens scaled. Eye round, HL; circumorbital tissues scaled, scale pockets particularly apparent in large spec- imens; anterodorsal rim of orbit projecting into profile in small forms, reaching profile in larger forms; interorbital width SL. Dentition variable with age (see Onto- genetic change); premaxillae, mandibles, vomer, and palatines dentigerous; tongue edentulous. Opercle bearing short, poorly ossified spine ventral to 1-8 membranous or poorly ossified spinelets; spine and spinelets sepa- rated by shallow gap; spinelets occasionally obscured by underlying membranes. Pre- opercle variable with age; angle rounded, slightly produced in s
