2.9 to 3.1; eye 3.2 to 3.8; postorbital part of head 2.2 to 2.4; least 

 depth of caudal peduncle 4.2 to 4.5; longest ray of pectoral fin 1.7; 

 longest dorsal spine 2.1; all in length of head. Least width of bony 

 interorbital 2.2 to 2.5 in eye; least depth of caudal peduncle in its 

 length 1.7 to 1.8; next to last dorsal spine in last dorsal spine 1.4 to 

 1.7 and in longest dorsal spine 2.0 to 2.2; length of first anal spine in 

 second 1.6 to 1.8; pel vies reach considerably past the vent, sometimes 

 to anal origin. 



This species lacks cirri on cranial spines, on lateral line pores, and 

 elsewhere except on top of nasal spine. The eye, lips, maxillaries, 

 interorbital space, snout, and chin are naked. Scales extend out from 

 bases of soft dorsal and anal rays a distance of from 2 or 3 scales to 

 not over a fourth to a third the length of pectoral rays out from 

 their bases. Palatine teeth present; upper jaw without notable 

 concavity at symphysis; spines at base of caudal fin not exposed. 



Color in aZcoAoZ.— General ground color light brownish, broken into 

 irregular bars by large whitish blotches. The most regularly distinct 

 bars are as follows: one crossing the caudal peduncle and one from 

 the soft dorsal fin to anal fin, another less distinct extending to area 

 of vent; usually a pale bar crosses base of caudal fin, then distal 

 two-thirds of that fin pale dusky; usually head and trunk finely 

 speckled with white. 



Color when alive. — All areas white in alcohol are lemon yellow and 

 dark bars reddish brown. 



Ecology. — This species occurs in any situation where there is ample 

 protection in crevices in the corals or among rather large growths of 

 coral and algae. 



Remarks. — After a careful examination of the type of Sebastapistes 

 coniorta Jenkins, I am convinced beyond doubt that coniorta of the 

 Hawaiian Islands and albobrunnea are distinct species. S. coniorta 

 with small brown spots everywhere on head, body, and fins may be 

 recognized at a glance. It is the same species, examined by me, that 

 Streets (p. 62, 1877) reported upon as Sebastapistes strongia, 

 USNM 15400. 



I have examined the holotype of Scorpaena aquaba Fowler, ANSP 

 72139, and believe it is the same species as Sebastapistes albobrunnea.
