 broad bands on jaws, vomer, and palatines ; dorsal spines stout, the last 

 spines very much shorter than the middle ones, and all depressible in a 

 deep groove; anal fin similar to soft dorsal, with 3 low, stout spines; 

 caudal fin broad, nearly truncate ; pectorals moderate ; ventrals long, 

 reaching vent. Color brownish, with large black blotches, becoming with

Stereolepis californiciis, GiLL, Proc. Ac. Nat. Sci. Phila., 330, 1863, California; substitute for gigas, 

 supposed to be preoccupied, but the Centropristis gigtis of Owen is Polypi-ion oxygeneios.

Body robust, moderately elevated, not much compressed, covered with 

 small, firm, ctenoid scales which extend on the bases of the vertical fins. 

 Lateral line complete, partly concealed under adjacent scales, the tubes 

 covering the whole length of the scale. Mouth large, the lower jaw pro- 

 jecting; maxillary with supplemental bone. Teeth in broad, villiform 

 bands on jaws, vomer, palatines, and tongue; no canine teeth. Head 

 scaly. Preopercle serrate ; orbital region with spinous projections ; opercle 

 with a strong spine and with a strong, rough, bony longitudinal ridge. 

 Gill membranes separate; gill rakers long, few. Dorsal fin continuous, 

 low, with 11 strong spines and 11 or 12 rays, the spinous portion longest ; 

 caudal rounded ; anal short, with 3 spines, the third the longest ; ventrals 

 large, inserted below, little behind pectoral ; caudal rounded or truncate; 

 pectorals short, unsymmetrical, of 18 or 19 rays, the upper longest. Spines

 cesses of premaxillaries not reaching frontals ; parietal and suiiraocular 

 crests not extending between j)ostfrontal processes; sujjraoccipital crest 

 strong, but not produced forward on cranium. Species inhabiting deep 

 waters in the warm seas, reaching a very great size. The one is confined 

 to the coasts of Southern Europe and neighboring waters ; the other

 Stereolepis gigas.
