Addi tionally, another unknown Pempheris species (Fig. 1) named ''Ryukyu hatampo'' in Japanese was recorded inOkinawan water. This species was reidentified to be P.adusta Bleeker, 1877 in our recent advanced research, and clearly distinguished from other Pempherid species by its number of pored lateral-line scales (54-62), scale rows ErrataReproductive biology of nocturnal reef fish Pempheris adusta (Pempheridae) in Okinawa Island, Japan

To clarify the life cycles of two species of genus Pempheris around Okinawa-jima Island, age and growth were examined using sectioned otolith. Monthly changes in the appearance frequency of an opaque ring on the outer margin of the sagittal otolith indicated that ring formation occurred once a year from April to June in both species. Ages were determined based on the number of opaque rings on the sectioned otolith, and the maximum ages observed for Pempheris schwenkii and Pempheris adusta were 6 and 16 years, respectively. Females had a longer life span than males in both species. The von Bertalanffy growth equations for both species did not differ between males and females, and were calculated as follows: P. schwenkii: L t = 111.2 {1 -exp [-1.53 (t ? 0.08)]}; P. adusta: L t = 138.8 {1 -exp [-0.84 (t ? 0.08)]}. No differences were seen in the growth of both species until 2 years old; however, at that point, the growth of P. schwenkii stagnated, whereas P. adusta continued to grow for three years. These data show that P. adusta and P. schwenkii inhabit the same environment and have similar morphologies, but different life cycle characteristics.
