cealed cycloid scales, the 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 side 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 specimen, 13 inches long, 

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

 branched; dsi/dpov, tree.)

Ancylossetta, GILL, Proc. Ac. Nat. Sci. Phila. 1864, 224 (quadrocellata). 



Body sinistral, broadly ovate, the depth more than 4- 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 ventral produced; vertebrae about 35. This genus is very 

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

 rakers, the rough scales, and in the prolongation of the anterior rays of 

 the dorsal fin. (ayuv Xoc,, hook; -^ijTra, turbot.) 



3002. ANCTLOPSETTA QUADROCELLATA, Gill. 



Head 3| to 3f ; 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 & length of head. Caudal 1| in head; ventral of colored side If. 

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

 small, the maxillary reaching to below middle of orbit, 2k in length of 

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

 strongly differentiated 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 \ 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, with 4 large, oblong, ocellated spots, the first above the arch of the 

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