and all of them are valued as food- fishes. The young are marked with 

 2 or 3 blackish lengthwise stripes. These disappear with age, quickest in 

 the brightly colored species, and persist for a long time in species like 

 bilineatus and interrupt us, which agree in coloration with Hcemulon parr a 

 and related speciss. (aVztfoS, unequal; Tptfjua, aperture, from the pores 

 at the chin). 



PARACONODON, Bleeker (napd, near ; Conodon) : 

 a. Scales above lateral line in series parallel with the lateral line. 



b. Dorsal spines rather low, the longest not more than length of head ; second 



anal spine about head. 



c. Pectorals much shorter than head, not reaching tips of ventrals; dorsal 



rays XI, 13, the spines comparatively slender, the longest head; eye 



more than twice as wide as the narrow preorbital. PACIFICI, 1681. 



cc. Pectorals a little longer than head, about reaching anal fin ; dorsal rays 



XII, 16, the spines short and stout, the longest 2J in head ; eye 3, about 



J wider than the broad preorbital. CLESIUS, 1682. 



bb. Dorsal spines very high, the longest If in head; second anal spine very long, 



about 1| in head; pectorals much shorter than head; iuterorbital area 



much less than width of orbit; snout obtuse, not much longer -than eye; 



cleft of mouth small, the maxillary extending to front of eye; dorsal and 



anal spines exceedingly strong, the third dorsal spine the longest; snout 



naked, the remainder of the head being scaly ; each ray of the soft fins 



accompanied by a series of minute scales, covering the caudal ; caudal fin 



slightly eruarginate. DOVII, 1683. 



ANISOTREMUS : 



aa. Scales above lateral line arranged in oblique series which are not parallel with it. 

 (/. Scales comparatively large, less than nine in a vertical series between first 

 dorsal spine and the lateral line ; coloration olivaceous, the adult nearly 

 plain, the young with 2 or more dusky lateral stripes which disappear 

 with age; fins blackish. 

 e. Scales 5 or 6-52-15 (lateral line with 49 pores) ; scales above lateral line on 



anterior part of body more or less enlarged, especially in the adult. 



/. Scales above lateral line not much enlarged, about 9 in an oblique 



series from first dorsal spine to lateral line; profile of head 



anteriorly rounded. SURINAMENSIS, 1684. 



ff. Scales above lateral line very much enlarged, especially in the adult, 



about 7 rows from first dorsal spine obliquely backward to lateral 



line; profile steeper and less curved. INTERRUPTUS, 1685. 



ee. Scales 7 or 8-46-15 (lateral line with 54 pores), scales above lateral line 



anteriorly not especially enlarged. BICOLOR, 1686. 



dd. Scales rather small, more than 9 in a vertical series between the first dorsal 



spine and the lateral line. 

 g. Body not striped longitudinally with yellow or blue; preorbital narrow; 



gill rakers a; +13. 



h. Anterior part of body without jet-black vertical bar; axil jet-black, 

 the spot encroaching on base of pectoral; a round black spot on 

 base of last rays of dorsal and anal; body dark gray, with 

 obscure darker streaks; fins pale, edge of opercle dusky; 

 pectoral long, 1 T V in head, reaching front of anal. 



SCAPULARIS, 1687. 

 hh. Anterior part of body with a black vertical bar. 



i. Body without lengthwise stripes ; dark humeral bar jet-black,
