point above anterior edge of orbit, where it is abruptly curved u]»ward 
and backward to the origin of dorsal fin; I'roin the latter j)oint it grailu- 
ally curves downward to base of iirst dorsal ray, from which the descent 
to caudal peduncle is abrupt ; ventral outline evenly curved from snout 
to caudal i)ednncle; interorbital space convex, its middle portion llattened ; 
orbit circular, nearer to posterior edge of opercle than to tip of snout, a 
distance equal to diameter of pupil; month oblique, lower jaw slightly 
projecting; lips thick; lower jaw with a frennm equal in widtli to ^ 
diameter of pupil; upper jaw i)rotractile ; maxillary covered by j)reorbi- 
tal excejit at its distal end; teeth in 2 series on each jaw, the outer series 
in a single row, Hat or incisor-like, larger in front, growing much smaller 
posteriorlj’, the inner series minute, in narrow bands, all the teeth loosely 
attached, their tips brown-colored; no teeth on vomer or i»alatiues; gill- 
membranes forming a fold across the isthmus; gill-rakers on first arch 10, 
short, far apart. Body covered with large, weakly-ctenoid scales; cheek, 
opercle, and occipital portion of head with small, c^vcloid scales; lower 
jaw, snout, and anterior half of interorbital space naked; bases of dorsal 
and anal fins with a row of small scales; auter-radial membranes of caudal 
with very small .scales on basal parts; lateral line interrupted on the 
nineteenth transverse row of scales, beginning again 3 scales lower down 
on the third row autei’ior to where it left off, and extending to base of 
caudal; 2 short rows of mucous tubes on inter-radial caudal scale.s, one 
abave and the other below end of lateral line; first dorsal spine shortest, 
others gradually longer and heavier, each spine with a ray-like attach- 
ment projecting above and posterior to its tip; first anal spine shortest, 
others gradually longer and heavier, the fourth three times as long as the 
first; spines with distal attachments similar to those of the dorsal, third 
and fourth rays longest, extending posteriorly as far as those of the dor- 
sal; posterior edge of caudal somewhat convex; iiectoral rounded; veil- 
trals pointed, the outer ray much the longest, extending a little beyond 
vent. Color in alcohol, light slate ; scales with lighter central sjiots; ])os- 
terior parts of dorsal, anal, and caudal lighter; in life the head was cov- 
ered with round and elongate spots of greenish blue on a background of 
golden brown; side of body with bluish and brownish spots without 
regularity of arrangement; pectoral and distal j)art of .soft dorsal with 
a yellowish tinge. 
In the young of this species there are 5 or d dark vertical bauds, about 
e(iual in width to diameter of orbit, on the posterior i>art of the body; a 
dark spot sometimes present just below lateral line on a vertical through 
base of eleventh dorsal spine. 
This species differs from X. nem a toj) us and X. vivaragitennin in having a 
much deeper body and fewer dorsal and anal spines. Laguna del Carpinte,
