margin of orbit; eye placed above premaxillary ; suborbital Avith 1 row 

 of scales, finely serrate behind middle of eye; 4 rows of scales on 

 cheek; preopercle finely sen-ale on upper limb, the serrse somewhat 

 larger at angle, a few on lower limb near angle; opercle with 2 obtuse 

 points; lateral line ceasing under third to fifth ray of soft dorsal, with 

 17 to 11> scales; margins of spinons dorsal nearly horizontal behind third 

 spine, the last and highest spine being 1| in head; soft dorsal somewhat 

 higher, pointed, the eighth and highest ray l^-in head; anal similar to soft 

 dorsal, its highest ray 1 ; in head; tip of soft dorsal extendiDg beyond 

 that of anal, almost to middle length of caudal; caudal forked, the lobes 

 rounded, the ripper a little longer than head, longer than lower, middle 

 rays of fin If in longest; ventrals slightly filamentous, extending beyond 

 origin of anal, slightly longer than the upper caudal lobe; least depth of 

 caudal peduncle greater than its length, 2 ,' ; in head; a row of scales on 

 the membrane of every ray in the vertical fins, those on spinous dorsal 

 larger and extending nearly to margin, those on soft portions of vertical 

 fins smaller (the rays being close together) and extending about halfway 

 to margins ; axillary scale of ventral not much developed. Nearly uniform 

 dusky, the tips of the scales lighter, thus forming more or less distinct 

 vertical streaks of light and dark; fins uniformly black ; a dark spot at 

 upper base of pectoral and another at lower; opercle darker than surround- 

 ing parts; a few very faint light points below eye. The specimens here 

 described have been compared with specimens of Eupomacentrux fuscus of 

 similar si/e, from Albrolhos Islands, Brazil, to which species they are 

 most closely related. Our specimens have the caudal more deeply forked, 

 the dorsal and anal higher, the vertical fins less densely scaled, the axil- 

 lary scale shorter, much longer ventrals, the caudal and pectorals not 

 lighter than other fins, and two dark brown spots at base of pectoral and 

 the axil entirely black. Jamaica ; types, 2 specimens, 4 inches long, No.

(PESCADO AZUL.) 



Head 31; depth 2; D. XII, 13; A. II, 13; scales 3-28-9 ; eye 4J-; snout 2f; 

 dorsal lobe 1 ; upper caudal lobe If; ventrals 1; pectorals "1J. Preor- 

 bital and preopercle strongly serrate. Teeth firm, flattened, not notched. 

 Caudal lunate, the upper lobe the longer; dorsal and anal rounded in 

 the adult, angular in the young; ventrals filamentous, reaching front of 

 anal; pectoral reaching vent. Gill rakers short, slender, weak, numer- 

 ous, about 10 on the lower limb; scales on head with numerous small 

 accessory scales wedged in between the others, especially on top of hed 

 and on opercle, 



"The color in extreme youth, as represented in a specimen 8 lines 

 long, is reddish brown, with blue lines obliquely crossing each scale, and 

 forming as many subvertical, scarcely interrupted blue lines crossing the 

 body as there are rows of scales. On the back and lower part of the
