height about equaling one half the distance from ventral to anal, 1.92 in head, and the length of 
base 2.4 in head; distance from posterior end of anal to lower caudal base, somewhat more than 
base of anal and about equaling distance from adipose to upper base of caudal, the least depth 
of caudal peduncle being 1.51 in this distance. 
Coloration . — Head and back purplish blue fading downward through lighter tones to steel 
blue, with purplish iridescence on sides, becoming pale rose, thence through deepening shades 
into deep crimson on under parts; ventral line whitish. Spots on sides dull orange above 
lateral line, becoming darker with an infusion of crimson below; dorsal like back, purplish 
brown on upper posterior margin; caudal of lighter purplish blue than back; pectoral, ventral, 
and anal fins deep crimson with white anterior edges.

Female , — Head 4.39 in length without caudal; snout, 3.66; eye, 4.88; upper jaw longer 
than in male (unusual), 2 in head; lower jaw, 1.82. Body somewhat more robust than in male, 
the depth equaling head; dorsal, situation similar to male, its rays 11, the longest equaling 
length of base, 1.62 in head; distance from posterior end of dorsal to adipose about equaling 
the distance from insertion of adipose to middle base of caudal, about 4.1 in length of body 
without caudal; distance from tip of snout to base of pectoral somewhat less than from dorsal 
to adipose; length of pectoral greater than that of ventral, 1.41 in head, the distance from its 
base to base of ventral 3.32 in length without caudal; ventral situated as in male, nearer tip of 
snout than middle base of caudal, the length 1.57 in head; distance from base of ventral to be- 
ginning of anal 3.71 in length without caudal; anal rays 9, the longest about equaling one half 
the distance from base of ventral to anal, and its base 2 in length of head ; distance from posterior 
end of anal base to lower caudal slightly greater than the distance from adipose to upper base of 
caudal, the least depth of caudal peduncle being contained about 1.12. 
Coloration . — Similar to male but much lighter shades and having smaller spots. 
From specimen 8g inches long.
