EVAPRISTIS (su, well; a, without, ffpicmjs, saw) : 

 aa. Soft dorsal and anal with a row of small scales on the membrane behind each ray. 



Preopercle entire; preorbital broad, 4| in head; mouth rather large. 

 g. Body rather elongate, in form intermediate between brevipinnis and chalceus; 

 back elevated and compressed, especially anteriorly; profile regularly 

 rounded; maxillary not reaching to opposite front of eye; gill rakers 

 moderate, #+14; snout long, moderately sharp; jaws snbeq.ua! ; scales 

 large; some series of scales on soft dorsal and anal, a row close behind eacl 

 ray. Dorsal fin rather deeply notched; spines low and slender; ana

 snout 2f ; maxillary 3^; orbit 4^; longest dorsal spine 2f; second anal 

 spine 3^; pectoral 1; ventrals If; upper caudal lobe 1. Body oblong, 

 compressed, the profile gently curved to dorsal. Head moderate, the jaws 

 subequal; teeth small, the outer a little enlarged; maxillary extending to 

 the vertical from posterior nostril; chin with median pit; interorbital 

 convex, its width about equal to orbit ; vertical limb of preopercle slightly 

 convex, finely serrated; gill rakers short, about 8 + 14= 22; preorbital 

 moderate, 3f in head, 3 in its least width. Snout, maxillary, and lower 

 jaw naked; scales on head small and crowded. Dorsal low, the longest 

 ray about 1 in the longest spine ; second anal spine not longer than third, 

 but slightly stouter, about half as long as longest ray ; pectorals moder-
