crowded, mostly ctenoid, those on head cycloid. Snout scaly, and 

 only very few obsolete maxillary scales. Dorsal origin about oppo- 

 site pectoral origin, third spine longest or slightly over one-third of 

 head. Soft dorsal inserted little nearer caudal base than hind pre- 

 operele edge; fin rounded. Spinous anal inserted about midway 

 between pectoral origin and caudal base, third spine longest or about 

 3i in head. Soft anal, like soft dorsal. Caudal rounded. Pectoral 

 broad, rounded, | to anal. Ventral origin slightly behind pectoral 

 origin, not quite rea,ching far back as pectoral tips or to rent, which 

 about an eye-diameter before anal. 



Color in alcohol dark brown everj^where except lower or ventral 

 edge with small blue dark-edged spots. On lower side spots more 

 sparse and less crowded than on back and vertical fins. Pectoral 

 also spotted, though ventrals plain brown, but both pairs with dusky 

 edges. Vertical rayed fins narrowly edged bluish. Brown line from 

 near snout tip to eye above, includes nostrils. Another below extends 

 along snout side horizontally till close under eye. Length, 344 mm. 



DIAGRAMELLA MACROPS (Pellegrin). 



Head, 3i to 3J; depth, 2| to 3; D. XIII, 15; A. Ill, 7; scales 100 

 to 108 along and above lateral line to caudal base, and 15 to 17 more 

 or less enlarged on latter; tubes, 56 to 58 in lateral line to caudal 

 base and about 10 more on latter; 12 scales above lateral line to soft 

 dorsal origm and 18 or 19 below to spinous anal origin; snout, 3 to 

 3^ in head; eye, 3| to 4; maxillary, 2^ to 2f ; interorbital, 3| to 4. 



Body elongately ellipsoid, well compressed. Caudal peduncle 

 strongly compressed, least depth 1| to IJ its length, or about 2§ in 

 head. Head deep, well compressed; width, 2 to 2^ its length. Snout 

 convex, long as wide or little shorter. Eye large, advanced or hind 

 pupil edge about midway in head length. Mouth moderate, jaws 

 about even. Maxillary beyond front eye edge, not quite to pupil, 

 expansion 2 in eye. Teeth small, in bands in jaws, and outer row 

 enlarged, especially forward. No teeth on roof of mouth or tongue, 

 latter elongate, roimded and free in front. Nostrils large, close to- 

 gether, front one about half an eye-diameter before front eye edge. 

 Interorbital convex. Hind preopercle edge with about 25 to 30 den- 

 ticles, smaU and obsolete below. GiU-opening forward about opposite 

 hind maxillary end. Rakers 14 + 20, lanceolate, about long as fila- 

 ments or two in eye. Pseudobranchiae slightly shorter than fila- 

 ments. Scales all finely ctenoid, in oblique series above and below 

 lateral line, smaller about body edges and on head. Snout to nostrils 

 and area around same, maxillary and also most of mandible, naked. 

 Suprascapula densely scaled, hind edge dentate. Cheek with 21 or 

 22 rows of scales. Pectoral with short concealed axillary scaly flap. 

 Bases of all fins scaly, and caudal largely covered with very minute
