ther the basic affinity of the Hawaiian ichthy- 
fauna with that of the Indo-Australian faunal 
province for which, of course, a redundancy of 
proof exists, and to indicate the marginal posi¬ 
tion of the Hawaiian ichthy-fauna in that 
province. The genus Petroscirtes has member 
species widely distributed throughout the west¬ 
ern tropical Pacific, but aside from one dubious 
record [Fowler’s remarks on Petroscirtes fila¬ 
ment osus (Valenciennes) (1928: 428)} no 
members of the genus have yet been reported 
from Hawaiian waters. The discovery of P. ewa- 
ensis establishes the existence of Petroscirtes in 
the Hawaiian portion of the Indo-Australian 
fauna province, but as it is a new species and 
hence never reported from any other portion of 
the province, this fact may be another bit of 
evidence of the relative isolation of the Ha¬ 
waiian portion of that province.
