3049. CITHARICHTHYS FRAGILLS, Gilbert. 



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

 D. 83 to 87; A. 67 to 70; scales 46 to 50. Vertebra 10 + 27. Body 

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

 anterior profile very conspicuously angulated above front of upper eye, 

 the snout strongly projecting, its anterior profile nearly vertical; depth 

 of caudal peduncle 2| 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, 2f to 2f 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 2| in head; interorbital space narrow, concave, scaled, the 

 lower ridge strongest, its width about i 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 ^ 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 vertebrse 

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

 California in from 18 to 76 fathoms, at Albatross Stations 3011, 3016 to 3018, 

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

3050. CITHARICHTHYS XANTHOSTIGMUS, Gilbert. 



D. 81 to 86; A. 63 to 67; scales 50. Vertebra 11+26. Body deep, 

 varying from 2 (in young, 3 inches long) to 2- 1 - L - (7 inches long) in length 

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

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

 vertical from front of the upper passing through front of lower pupil. 

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

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

 sharp downward-directed point at symphysis. Teeth in a single close-set 

 series in each jaw, growing slightly larger anteriorly, but without canines.
