3049. CITHARICHTHYS FRAGILIS, Gilbert. 



Head 3g to 3| iu length; depth 2| to 2f (in specimens 5 inches long.) 

 I). 83 to 87 ; A. 67 to 70 ; scales 46 to 50. Vertebr:P 10 + 27. liody 

 elongate, posteriorly sharply wedge-shaped, tapering to base of caudal; 

 anterior pvotile very conspicuously auguluted above front of upper eye, 

 the snout strongly projecting, its anterior profile nearly v'crtical; depth 

 of caudal peduncle 2J^ in head. Anterior nostril with a short tube and 

 flap, the latter nearly obsolete on blind side. Mouth more oblique than in 

 C. sordidus; maxillary reaching vertical from front of pupil, 2* to2^ in head. 

 Teeth in a single series, close set, those anteriorily somewhat enlarged, but 

 none of them canine-like. Eyes large, the vertical from front margin of 

 upper eye falling through front of lower pupil; longest diameter of 

 upper orbit 23 in head; interorbital space narrow, concave, scaled, the 

 lower ridge strongest, its width about ^ diameter of orbit. Symphyseal 

 knob sharp. Gill rakers long, slender, close set (as in C. sordidus), 18 on 

 anterior limb of arch, the longest ^ orbit. Scales large, deciduous, 

 somewhat irregularly arranged, 12 or 13 series above lateral line; scales 

 smooth on blind side, minutely spinous on eyed side; lateral line with- 

 out anterior arch. Dorsal beginning slightly in advance of eye, the long- 

 est ray i head ; pectorals long and narrow, with 11 rays on colored side. 

 Color dusky olivaceous, with occasional slaty-blue spots. This species is 

 closely related to C. sordidus^ from which it differs in the fewer vertebrte 

 and fin rays and in the larger scales. Many specimens from the Gulf of 

 California in from 18 to 76 fathoms, at JJbaii-oss Stations 3011, 3016 to 3018, 

 and 3033. (Gilbert.) {fragilis, fragile.)

 of body. Profile angulated above front of upper eye, the snout convexly 

 projecting. Depth of caudal peduncle ^ head. Lower eye in advance, the 

 A'ertical from front of the upper jiassing through front of lower pupil. 

 Mouth rather small, the outline somewhat curved, the maxillary reaching 

 the vertical from front of lower pupil, 3 to 3^ in head; mandible with a
