Tabi.k 1. — Locations and dates of capture of 115 specimens of Kyphosus seetatrix 



by Dr. Paulo de Minmda Ribeiro, August 28, 1959 

 (written communication), fell within the ranges 

 found for K. seetatrix, except the eye diameter 

 w^hich was 6.8 percent of standard length. In my 

 K. seetatrix above 150 mm., eye diameters ranged 

 7.5-10.2 percent of standard length. 



The description of K. incisor by Pilrr (1930) has 

 all the distinguishing features of K. seetatrix. 



The description of K. i?icisor by Fowler (1944), 

 which was later changed to K. palpehrosus by 

 Fowler (1953), also has all the distinguishing 

 features of K. seetatrix, including eye diameter. 



The description of the specimen identified as 

 K. lute.seens by Carvallio (1950) from the Isle of 

 Trindade, Brazil, is the same as that found for 

 K. seetatrix except for the color and the number 

 of scales. I found the color of K. seetatrix to be 

 variable. Carvalho (1950) listed 98-101 scales, 



a count higher than that given for the holotype 

 of K. lute.seens by Jordan and Gilbert (1881) or 

 for either K. lutescens or K. seetatrix by Jordan 

 and Evermann (1898) [whom Carvalho (1950) 

 used for comparisons]. Carvalho (1950) did not 

 indicate the location of scales counted. I have 

 not examined the relationship of the Pacific 

 species K. luteseens with K. seetatrix. 



The record of K. seetator Tortonese (1954) is 

 of the same specimen named Pimelepterris boscii 

 var. sicula by Doderlein (1884) whicli is placed in 

 synonymy.
