cealed cycloid scales, tlie free edges of which are notched to the opening 

 of the pore ; these scales entirely covered by the integument, and from 

 the pores there proceed backward membranaceous tubes, ramifying over 

 the bases of contiguous scales ; this is true also of lateral line of blind side ; 

 eyed Bide entirely scaled except snout and mandible. Vertical fins cov- 

 ered with thick skin, each ray accompanied by 1 or 2 series of ctenoid 

 scales; left ventral also scaled. Color olive brown, with 3 large black 

 ocellated spots larger than orbit, the posterior one on lateral line in front 

 of caudal peduncle, the 2 anterior under middle of dorsal, halfway between 

 lateral line and dorsal and anal outlines, respectively ; each spot with a 

 light center; distal portion of vertical fins more or less brown on right 

 side. (Gilbert.) Gulf of California. A single sjiecimeu, 13 inches long, 

 from Albatross Station 3022, in 11 fathoms, {dendriticus, like a tree, 

 branched; SsvSpov, ii:ee>.)

Body sinistral, broadly ovate, the depth more than 1 length; mouth 

 moderate; teeth uniserial, unequal, some of the anterior enlarged; cau- 

 dal fin with a very short peduncle; scales very strongly ctenoid on both 

 sides of the body; anterior rays of dorsal notably exserted, the rays of the 

 anterior part of the fin elongate, thus forming a distinct lobe; gill mem- 

 branes considerably united; gill rakers short and broad, with rough 

 teeth; left Aentral produced; vertebra:- about 3.5. This genus is very 

 close to Faralicldluis, differing in the subsessile caudal fin, the short gill 

 rakers, the rougli scales, and in the prolongation of tht^ anterior rays of 

 the dorsal fin. {ayHvXoi, hook; ipfJTra, tnrbot.)

Head 3| to ^^, depth If. D. 70 to 76; A. 57 to 59; pores in lateral line 

 83 to 90; vertical series of scales 70; fourth or fifth dorsal ray longest, 

 nearly f length of head. Caudal l.l in head; ventral of colored side If. 

 Body oval, compressed, very deep; an abrupt angle above eye; mouth Aery 

 small, the maxillary reaching to below middle of orbit, 21 in length of 

 head; teeth comparatively small, about 14 on each side of lower jaw; no 

 strongly difterentiated canines in either jaw. Eyes moderate, separated 

 by a very narrow, sharp, scaly ridge; gill rakers very short, thick, few in 

 number, 2 -f 6 or 7, the longest less than A diameter of pupil ; scales 

 rather small, very strongly ctenoid, those on blind side also rough; curve 

 of lateral line rather low ; tubes of lateral line simple ; dorsal beginning 

 in front of pupil, its anterior rays long and filiform, much exserted; cau- 

 dal short and rounded, If^ in head ; ventral fin of colored side rather long, 

 as long as pectoral, \ length of head ; anal spine wanting. Brownish 

 olive, Avith 4 large, oblong, ocellated spots, the first aboA^e the arch of the 

 lateral line; the 3 posterior forming an isosceles triangle, the hindmost
