 somewhat irregular, dusky cross bars. Length 9 inches. Coast of south-

2274. TARANDICHTHYS TENUIS (Gilbert). 



^Head 3 to 3f ; depth 5J to 5; efe 3J to 3 in head. D. X-17 to 19; A. 

 15 to 17. Body slender, tapering into a very slender caudal peduncle, 

 whose depth is less than its length, and - diameter of orbit. Eye large, 

 longer than snout; maxillary reaching slightly beyond middle of orbit, 

 2.V in head. Bands of teeth narrower than usual, present on jaws, vomer, 

 and palatines. Interorbital space narrow, - diameter of pupil, slightly 

 concave posteriorly, the ridges converging anteriorly and meeting above 

 front of pupil ; upper preopercular spine smaller, about as long as pupil, 

 with a short terminal process, and 2 or 3 upwardly directed ones; below 

 this a simple spine directed backward, and 2 directed downward and for- 

 ward ; nasal spines strong ; 2 strong spines behind upper edge of orbit, 

 and a single sharp one at end of occipital ridge ; occipital region gently 

 concave; 110 pit behind eyes; no spine on oporcle or suborbital, and no 

 distinct spine on shoulder; a simple black flap on upper rim of orbit pos- 

 teriorly; no other flaps on head, and usually none on plates of lateral 

 line; plates of lateral line as in related species, 41 in number; dorsal 

 scries of plates arranged in a double row as usual, but very short, begin- 

 ning under fifth dorsal spine and ending under first third of soft dorsal, 

 its length varying from slightly longer than head to f- its length, double 

 throughout; sides immediately behind axil of pectorals with about 15 

 plates similar to those of lateral line, but smaller, scattered or showing a 

 tendency to regular arrangement ; first ray of spinous dorsal very slender, 

 filamentous, varying in length, in adults reaching end of soft dorsal, the 

 second spine sometimes sligtly produced, but never long ; the 2 dorsals 

 entirely disconnected, the height of soft dorsal or f length of head ; 

 pectorals long in males, reaching much beyond front of anal, as long as 

 head ; ventrals nearly f orbit. Color light olivaceous above, white below, 

 the back with 4 black crossbars, the first under spinous dorsal, the second 

 and third under anterior and posterior parts of soft dorsal, the fourth at 

 base of caudal; back and sides, including head, with pearly dots and 

 lines ; those on upper parts frequently curved and margined with dark ; 

 spinous dorsal with a small dark blotch posteriorly, and some dusky
