ART. 33. NOTES ON FISHES OF HAWAII E. K. JORDAN 33 



The type is Cat. No. 87418, IJS.N.M., taken by me in the market 

 of Honolulu. In the museum of Stanford University are No. 8781, 

 from Honolulu, and 8784, from Samoa. Also 23374, from Honolulu. 



This fairly common species is well figured and described in Jor- 

 dan and Evermann (from whom the above diagnosis is modified) 

 as Callyodon dubius Bennett, following Giinther. The name duhius 

 however, has been shown to belong to the fish later called Scarus 

 hennetti; by Cuvier and Valenciennes, and the present form is left 

 nameless. 



{Galena — ^lead ore, a dark gray lead sulfid mineral, from the life 

 color.) 



SCARUS BRUNNEUS Jenkins. 



A specimen about 2 feet in length, apparently belonging to this 

 species, was seen in the Honolulu market. The fish being so large, 

 only the head was taken, but this agrees well with Jenkins's type. 

 The color was dark reddish brown, the vertical fins broadly edged 

 with a dusky wash. An inconspicuous posterior canine is present; 

 in a smaller fish, hoAvever, this would easily be overlooked. No 

 specimen of Scarus hrunneus has previously been reported over 9 

 inches in length. 



SCARUS BATAVIENSIS Bleeker. 



Recorded from Honolulu by Steindachner. 



Genus PSEUDOSCARUS Bleeker 



Those species of Scarus having the jaws blue may properly be 

 regarded as generically distinct from those with the jaws whitish 

 or pale rosy. The blue coloration is permanent, is found at all ages, 

 and is not altered by preservation in spirits. It seems to represent a 

 very high degree of specialization. The body coloration in this 

 group, usually, but not always, green or blue, is more specialized 

 than that of Scarus proper.
