BULLETIN OF THE UNITED STATES FISH COMMISSION. 
a series of 4 scales on median line in front of first dorsal spine. Caudal fin convex, lobes rounded, 
length in head 1.26; height of caudal peduncle 2 in head; pectoral 1.35 in head, breadth being more 
than half its length; ventral 1.8 in head, not reaching vent by about half its length, inserted on a 
vertical from posterior limit of base of pectoral; dorsal spines flexible, but little less in height than 
soft portion, which equals soft anal in height. 
Coloration in life: Head, body, and fins uniformly brown, with reddish tinges, which are more 
pronounced on fins and throat. Base of caudal paler. No distinct markings on any part of body. 
Three specimens obtained by me of a total length of 218, 192, and 156 mm., respectively. One in 
Dr. Wood's collection is 237 mm. The fish was not rare, as it was frequently seen in market. It 
is not distinguished from Scarus paluca and brunneus by the fishermen. They are exposed for sale 
together and bring very high prices. Type No. 6142, L. S. Jr. University Museum.
