scales on his new C. viridifucatus but Mrs. Smith's color drawing 

 shows only 4, a number wtiich agrees with my observations on the 

 basis of counts and coloration. I refer Smitli's species to S. lunula 

 with some doubt. An important character is the red margin of 

 operculum, as shown in Smith's color drawing. 



I have studied specimens in lots from the following localities: 

 Marshalls, 1 lot; Moluccas, 2; Borneo, 2; and Philippines, 7.

This species is characterized by having 4 median predorsal scales, 

 usually with a pair in front of the anteriormost median scale, 3 rows 

 of scales on the cheek, with 1 or 2 scales in the ventral row; white 

 teeth; and ii,12 pectoral rays. The color pattern is shown in plate 

 10, c. The young of S. formosus have dark and light streaks on the 

 sides of the body. In the adult the forehead is enlarged, giving 

 to the head a strongly convex dorsal contour. 



The lips do not quite cover the white teeth, the angle between edges 

 of upper and lower lips varies between 10 and 20 degrees; the inner lip 

 joins the outer near the symphysis; 1 or 2 canine teeth occur near the 

 corner of the mouth on adults; distal margin of caudal fin a little 

 rounded in young, becoming forked in adults. 



In alcohol, the two small specimens (52 and 81 mm.) are plain light 

 brownish with traces of dark and light streaks on the sides. The color 

 pattern of the adult is illustrated in the plate. 



The color when alive is described in the following notes, provided by 

 John Randall: "Green with scales rimmed in rose; region of pectoral 

 and posterior part of head below eye and behind eye dull yellowish 

 tan, grading to yellow ventrally and to yellow-orange anteroventralLy; 

 upper part of head bright green; upper lip yellowish green; on chin,
