FISHES OF THE PHOENIX AND SAMOAN ISIANDS 105 



Family SERRANIDAE 



My material of this family from the Phoenix and Samoan Islands 

 does not include enough of the species reported from the Polynesian 

 area to justify the construction of a key to the various species (see 

 table 11).

EPINEPHELUS URODELOPS, new species 



FiGUKE 8 



Holotype.— The only specimen known (U.S.N.M. No. 115366), 85 

 imn. in standard length, taken by L. P. Schultz on May 25-26, 1939, 

 in the lagoon of Canton Island. 



Description. — (Based on the holotype. All measurements are ex- 

 pressed in hundredths of the standard length.) Length of head 41.8; 

 greatest depth of body 37.4 ; length of snout 9.9 ; diameter of eye 9.2 ; 

 length from tip of snout to rear edge of maxillary 21.2 ; postorbital 

 part of head 24.3 ; least depth of caudal peduncle 15.3 ; length of caudal 

 peduncle measured from rear base of anal fin to mid-base of caudal 

 fin 18.5; distance from snout to origin of dorsal fin 42.8; distance 

 from snout to origin of anal fin 70.0 ; distance from snout to center of 

 anus 64.8 ; interorbital space 6.2 ; length of pectoral fin (base of fin to 

 tip of longest ray) 28.0; length of caudal fin 24.7; length of pelvic fins 

 20.5 ; second anal spine 17.6 ; dorsal rays XI, 8 ; anal III, 8 ; pectoral 

 rays left 16, right 17 ; pelvics 1, 5 ; gill rakers on first gill arch 8+1+15 ; 

 scales in row from base of first dorsal soft ray to lateral line 8, and 

 number of scales from base of first anal spine to lateral line total 21 ; 

 scale rows crossing lateral line from upper edge of gill opening to 

 base of caudal fin 79. 



The third dorsal spine, as are all that follow, about two-thirds 

 length of soft dorsal rays ; second anal spine strongest, a little longer 

 than the third; lower opercular spine a little closer to the middle one 

 than the upper is to the middle spine ; lateral line extending upward, 

 its highest (dorsal) point is under base of seventh dorsal spine, thence 

 it continues in an almost straight line to midaxis of body just below 

 posterior end of base of soft dorsal, continuing along midline of 

 caudal peduncle and outward on base of caudal fin for a distance equal 

 to two-thirds diameter of eye; teeth depressible on lower jaw, and 

 arranged in several series at front of jaw but posteriorly in only one or 

 two irregular rows, the inner teeth canines ; at each side of tip of lower 

 jaw is a strong, nondepressible canine tooth ; at each side of the tip of 

 the upper jaw are one or two strong, nondepressible canines, behind 

 these are patches of long brushlike teeth that are depressible ; sides of
