about seven dusky cross bauds. Some dark, inky spot-; ou opeicle and 

 above base of pectoral. Opercle and preopercle with dusky shades. 

 Chin with some dusky. Spinous dorsal plain. Soft dorsal with fine 

 oblique bars on a i)ale ground, two of the dark blotches on body extend- 

 ing on its base. Last ray with two or three dark spots. Caudal fin 

 with the middle rays black, the outer pale, all of them with darker 

 sjiots, which become black on the median rays. 



Anal tin pale, slightly mottled, the tips of its rays dusky; ventrals 

 dusky ; pectorals entirely pale. 



Caudal tin with its upper and lower lobes filamentous, much produced, 

 the middle rays still longer, exserted for a distance nearly equal to f 

 length of head, the total length of the longest ray being half the length 

 of the body. 



Dorsal spines not filamentous, the longest 2J in head. Pectorals If 

 in head, reaching a little past tips of ventrals. 



Scales on cheeks a little larger than in S. atrarius, in about 7 rows. 

 Serrae of preopercle smaller than in iSerranus atrarius. 



Gill-rakers shorter and farther apart than in Serranus atrarius, only 

 11 or 12 developed. (In Serranus atrarius about 20 are present.) 



In spite of the striking differences in color, in which this species con- 

 siderably resembles the very young of S. atrarius, the details of form 

 and structure are almost identical in the two species, and the present 

 should probably be considered as the Gulf representative of the 8. 

 atrarius. 



4. Scarus evermanni Jordan, sp. nov. 



Head 2| (3J in total) ; depth 2f . Length of type (No. 37990, U. S. N. 

 M.) 3 inches. 



Very close to Scarus croicensis, and similar to it in pattern of color- 

 ation except that the sharply-defined streaks on the sides of the breast 

 are in S. evermanni inky-blue, in S. croicensis whitish. 



In life, the type of Scarus evermanni was bright green, olivaceous 

 above, paler below; the lower half of the body becoming posteriorly 

 more and u)ore yellow and on the lower half of the caudal peduncle 

 bright light yellow ; this color is brightest above front of anal. 



A longitudinal band of bright crimson (fading to whitish in spirits) 

 on body, on level of eye, but narrower than eye and growing fainter 

 behind. Some crimson marks on the scales above this band forming 

 a faint interrupted band below lateral line. Both these bands con- 

 tinued on head to eye with a band of green (brown in spirits) be- 

 tween them. Sides of belly each with three sharply-defined lines of 

 indigo-black, like ink-marks, each on a row of scales; these stripes run- 

 ning from the breast to beyond front of anal. No spot on base of pec- 

 toral. Bright green on top of head above eyes, reddish below. Caudal 

 fin green, its lower half yellow. Dorsal, anal, and pectorals (mutilated 

 in the type), apparently all green, at least at base. Ventrals yellow.
