Otolithus tridentifer Richardson is probably a synonym, like several 

 other nominal forms I unite with this species. It is imperfectly 

 noticed : 



Two strong upper canines and one below near symphysis, with equal 

 row of lateral subulate teeth in both jaws, more close set in lower and 

 (under lens) narrow vilHform band within others above and below, 

 few intermixed with principal ones; preopercle armed feebly by small 

 acute teeth; opercle with 2 narrow spines. D. X, i, 27; A. II, 6; P. 15. 

 Pale silvery, with slight bluish gray tint along back. Lower half of 

 caudal, front of anal, and paired fins gallstone yellow. Rest of fins 

 pale and spotless, upper half of caudal alone deeper and approaching 

 blackish gray. 



Otolithus aureus Richardson is noticed: 



Maxillary striated, truncated; 5 pores at mandible tip; row of 

 subulate teeth on upper jaw, villiform band within and canine near 

 symphysis; lower laterals with no vilUform bands within subulate 

 teeth and but 2 or 3 rows of minute ones exterior; preopercle edge 

 streaked, slightly crentedentate; opercle spines 2, narrow, acute, 

 triangular, flat. Preorbital and snout scaly. D. X, i, 25; A. II, 9, 

 first spine almost concealed, second slender, half length of soft rays. 

 Dark, with much brown, unspotted on body. Two rows of spots 

 between rays on second dorsal. Pectoral and lower fins orange. 



Otolithus reevesii Richardson is said to be like Otolithus aureus, but 

 differs in the more blunt, rounded, and prominent snout, shorter 

 rounded caudal, less cuneate and preopercle spinously toothed on 

 upper limb and rounded corner, where teeth large; on its under limb 

 teeth have usual crenate dentate character. Dentition and pores as 

 in 0. aureus. D. X, I, 31, more deeply divided than in 0. aureus and 

 2 equal tips of bony opercle shorter and stronger; A. II, 7, second 

 spine shorter than soft rays, stout and finely striate; P. 19. On upper 

 half of body oblique fines, which pass same way below lateral line.
