considerably more than interorbital width. Interorbital concave, 2 strong 

 ridges dividing it into a median and 2 lateral grooves; preorbital narrow, 

 with 2 flat spine processes. Preopercular spines directed backward. Gill 

 rakers about 2 in orbit; second anal spine 2 in head; maxillary, man- 

 dibles and snout naked ; scales mostly cycloid. Lower pectoral rays thick 

 and lleshy. Three straight, dark cross bands, 1 from nape across base of 

 pectoral, 1 from sixth to seventh dorsal spine; toward anus, a half one from 

 eighth to tenth dorsal spine to lateral line, a broader one below soft dorsal ; 

 these bars extend on to the dorsal fin ; a few small dark spots on base of 

 pectorals and on shoulder; sides of tail more or less mottled ; dark streaks 

 radiating from eye; peritoneum pale. Specimen, 8| inches long; San 

 Francisco. The type specimen belongs to the collection of the Indiana 

 University. (Eigenmann & Beesou.) (Named for William HealyDall, of 

 the Smithsonian Institution, who has been intimately identified with the 

 Pacific coast zoology for many years.

Head 3; depth 2|. D. XIII, 13; A, III, 6; scales 47. Body oblong, 

 deepest at the shoulders. Head sliort, blunt. Mouth moderate, little 

 oblique, maxillary reaching to posterior margin of eye, its length 2J- in 

 head; prernaxillary rather below level of eye; jaws equal, without 

 symphyseal knob. Eye small, anterior, 4 in head. Preopercular spines 

 short and stout, the 2 upper subequal ; opercular spines very broad and 

 flat, sometimes bifid; suprascapular spines strong. Gill rakers very short, 

 wide, compressed, the longest almost as wide as high. Scales on body 

 large; accessory scales few. Dorsal spines low, the fifth about the 

 length of head; the fin little emarginate; soft rays considerably higher 

 than spines ; caudal slightly rounded ; anal high, its spines low, the second 

 as high as third and much stouter, 3 in head; pectoral rather short, reach- 

 ing vent, its base extremely broad, its width about \ length of head; the 

 lower rays much thickened; length of pectorals 3f in body; ventrals 

 moderate, not quite reaching the tip's of pectorals. Bones of skull thick; 

 preocular, postocular, tympanic, and parietal spines present, strong, the 

 ridges low but thick; occipital ridges very long, equalling diameter of 

 orbit; parietal bones separate; interorbital space 4 in base of skull, 

 slightly convex, concave laterally inside of supraocular ridge narrower 

 than eye; ventral process of basispheuoid well developed; mesethmoid 

 processes compressed, strong, slightly elevated; base of skull very nearly
