No scales on snout anterior to nostrils; depth of body about 2.6 in 

 standard length; width of body about 2.7 in depth; upper margin of 

 preopercle smooth; no concavity in preopercular margin; caudal fin 

 truncate to slightly rounded. 



The usual color in alcohol is brown with a pale lengthwise band 

 which begins beneath spinous portion of the dorsal fin and follows 

 the lateral line to the upper base of the caudal fin; a diagonal U-shaped 

 mark behind eye; 2 to 4 dark-edged pale transverse bands (which 

 may be broken into 2 or more elongate spots) on interopercle. 



Color in life of specimens collected by the author in the Tuamotus : 

 light gTayish brown, the centers of the scales a little paler than edges, 

 resulting in a faint lengthwise banding; a broad lengthwise pale pink 

 to white band running over region of lateral line from beneath base of 

 about the seventh dorsal spine to caudal fin; a large U-shaped area, 

 only slightly darker than rest of head and enclosed by a tricolored 

 border of bright orange, dark brown, and outwardly light blue, ex- 

 tending diagonally upward from rear of eye; three bright orange bands 

 cross interopercle, the uppermost at edge of opercle, these bands 

 narrowly edged with dark brown and broadly with pale blue; anterior 

 nostril, tips of snout above upper lip, front edge of lower lip, maxillary 

 and premaxillary groove bright orange; fins light yellowish brown. 



Remarks.— Occasional specimens of arcatus, which may be either 

 male or female, are dark brown and lack the lengthwise pale band on 

 the body. Giinther (1874, p. 70, pi. 49, B, C) illustrated both forms 

 and regarded them as color varieties. Specimens intermediate in 

 color have been examined, and no meristic differences between the 

 two forms were ascertained (see table 2 for comparison of lateral-line 

 scale counts) ; Giinther's judgment, therefore, seems correct. 



A syntype of arcatus from Mauritius (MNHN 2854) measures 

 82 mm. in standard length and is well preserved; it is here designated 

 as the lectotype, and the type locality is thus restricted to Mauritius. 



This Indo-Pacific species is at least as widespread and abundant 

 as P. forsteri. Largest specimen examined, 111 mm. in standard 

 length, from Hawaii.
