PEMPHERIS OTAITENSIS Lesson 



Pempheris otaitensis Lesson, Voyage autour du monde . . . CoquiUe, Zool., 

 vol. 2, pt. 1, p. 167, 1830. 



The dentition of the mandible and premaxillary appears to change 

 somewhat at about 165 to 180 mm. standard length. Fishes of the 

 latter lengths have their teeth so enlarged and developed that they 

 can be seen when the mouth is closed each side of the tips of the 

 dentary, the outer teeth pointing outward; those on the upper jaw 

 are similar but less developed. This change in dentition with age 

 causes me to cast doubt on the key by Weber and de Beaufort (Fishes 

 of the Indo-Australian Archipelago, vol. 7, pp. 212-213, 1936) in the 

 separation of P. oualensis and P. otaitensis. At least the specimens 

 of this type from the Phoenix and Samoan Islands I cannot separate 

 into two species.

Family LUTIANIDAE 



The species and number of specimens available from the Phoenix 

 and Samoan Islands are too few to attempt to make a key to the 

 lutianids that would properly distinguish the various species.
