fin and sixth bar across middle of length of caudal fin ; the tips of the 

 caudal fin rays are usually dusky, making up the seventh bar. A 

 broad blotched bar from orbit across cheek and other dark blotches 

 on operculum; interorbital dusky; pectoral more or less barred; 

 pelvics with a bar across middle. 



Color when alive. — Dark blotches reddish brown, paler areas olive 

 to whitish. 



Ecology. — This species, similar to the other scorpaenid fishes of the 

 northern Marshall Islands, prefers the protection of corals and other 

 crevices in the reefs. 



Remarks. — After examining the two paratypes of S. mcadamsi 

 Fowler, USNM 99013, I doubt that these are of the same species as 

 the holotype. One lacks the occipital pit and the other has a striking 

 difference in the arrangement of the cranial spines on the dorsal part 

 of the head at rear of orbits. The one with the occipital pit has the 

 rear preorbital spine directed posteriorly instead of downward and 

 curved forward as in the holotype and in all the specimens from the 

 northern Marshall Islands.
