Rows of scales on body horizontal; equal in size above and below 

 lateral line. Snout, upper surface of head, preorbitals, mandibles, 

 and margins of preopercle 

 naked ; temporal patch with 

 four transverse rows, six 

 longitudinal; preopercle 

 with six rows of scales, 

 opercle, sub-and interoper- 

 cle completely scaled; a 

 small patch on base of 

 pectorals, and densely 

 crowded rows on interray 

 membranes of caudal to 

 tips, none on other fins. 



Color of old alcoholic 

 specimen silvery, slightly 

 darker above. Naked parts 

 of head dark brown, darker 

 on upper edge of mandibles, 

 and below end of maxil- 

 lary. Fins pale. In life 

 reddish brown, the forehead 

 {fiavivultus) sometimes 

 bright yellow. 



The synonymy of this 

 species is very difficult to 

 decide. A-phareus rutilans, 

 as described by Cuvier and 

 Valenciemies, differs from 

 Aphareus furcatus in having 

 the fourth, fifth, and sixth 

 dorsal spines longest, and, 

 according to Gtinther " and 

 also Klunzinger, the pec- 

 toral rays are produced 

 below, the depth is less than 

 the head, the snout is longer, 

 and the eye smaller. The 

 two last-mentioned authors 

 had specimens 14 inches 

 and 70 cm. in length, re- 

 spectively, and some of the 

 differences, as those in 

 depth of body and size of eye can safely be attributed to age. 

 The lower lobe of the pectoral becomes longer with age, as stated by 



o Sudsee Fische.
