Described from two specimens, 220 and 460 mm. long, from 

 Caloundra Banks, Australia, and from Wanganui, New Zealand, 

 respectively. 



Head 3 in body length; depth 2|; eye 3| (5^ in large specimen) 

 in head; depth of preorbital 3f; snout 2J; maxillary 2|^; D. XII, 10; 

 A. Ill, 8; scales in lateral line 57, in transverse series between inser- 

 tions of dorsal and anal 9 or 10/17; gill-rakers 8 + 11. 



Body deepest before insertion of dorsal, tapering posteriorly, 

 head profile very steep, and but shghtly arched, save at occiput. 

 Length of maxillary equal to that of preorbital, which is 1^ times its 

 depth. Distance between nostrils equal to length of posterior one. 

 Width of preopercle less than that of scaled cheek, its margin ribbed, 

 but not serrate. Teeth as in Pagrosomus major, in two series in both 

 jaws, the inner molar like, the outer more conical, inner row becoming 

 replaced by minute granular teeth, outer becoming more conical 

 anteriorly. Two pairs of canines above and three below in front. 

 Gill-rakers short and stout. 



Fourth dorsal spine highest, 2| in head, not produced; second and 

 third anal spines subequal, 3^ in head; pectoral equal to head plus 

 half eye, its lower rays somewhat produced; ventrals If in head, 

 reaching anus; caudal deeply forked, its lobes equal to head. 



Scales not present on vertical fins save as low sheath, nor on 

 preorbitals, snout before eyes, lips, or jaws. An occasional scale on 

 the preopercle. Cheeks with 7 or 8 rows. 



Color silvery, darker above, fins uniform. 



Cranial crests as in Pagrosomus 7najor, the inner or parietal little 

 developed; supraoccipital crest inserted above anterior margin of 

 eye, its upper edge thickened by hyperostosis as in Evynnis cardi- 

 nalis. First spurious interneural also thickened. 



Pagrosomus auratus, the most abundant and valuable of Aus- 

 tralian food fishes, has been recorded several times from Chinese 

 Seas and by Regan from the Inland Sea of Japan, under the name of 

 Pagrus unicolor. None of the authors give any details regarding 

 their specimens, however, and it is not impossible that all of them are 

 really Pagrosomus major, to which P. auratus is closely related. The 

 latter differs mainly in these regards: A larger eye in specimens of
