Pelvic fins reach base of anal in some specimens; anterior margin of preopercle smooth, posterior margin finely serrated; lateral line com- plete ; ctenoid scales with 9 to 16 radii. Color in alcohol.—Body and head light tan, sometimes darker tan; chin and belly dusky to silver; five horizontal dusky brown stripes. Figure 80.—Holotype of Jpogon robustus (Smith and Radcliffe) ( No. 68400), Jolo Island, P. I. extend from head to caudal peduncle or caudal fin; dorsal, dorso- lateral, and midbody stripes well developed and usually not faded; ventrolateral and ventral (belly) stripes faint, sometimes obscure; dorsal stripe begins at about the region of the midhead, between the eyes, and extends to base of spinous dorsal, dividing and passing around base of dorsal, uniting at end of soft dorsal and extending from dorsal side of caudal peduncle to tips of outer rays on lobes of caudal fin; dorsolateral stripe extends from snout, over eye on body just above lateral line to upper portion of caudal peduncle and ending on the lower fourth of the base of the rays of the caudal fin; median stripe passes from tip of snout through middle of eye and on midbody to midbase of caudal fin, where it is enlarged, forming an elongate, diffuse spot; horizontal diameter more than twice the vertical diameter and horizontal diameter about to in eye; a streak passes from spot to fork of caudal fin; caudal spot variable in its development from faint
