both jaws aacl on vomer, iioue of theui ealarged ; palatines witli a 

 single series. Posterior nostril elliptical, not twice as long as it is 

 wide. Eye 2^ in head ; interorbital width 3.'^ ; length of snout 5. 



Preopercalar and preorbital margins serrate, a group of stronger 

 spines at angle of preopercle. Gill rakers short, about half diameter 

 of pupil, IG developed on horizontal limb of outer arch. 



Spinous dorsal high, the longest spine f length of head ; the first 

 and last spines much shorter, about equaling the soft rays. Anal 

 spines similar but shorter, the first two equal and longer than the third, 

 their length half" that of head. Pectorals short, barely reaching verti- 

 cal from vent. Ventrals elongate, the spine reaching base of second 

 anal spine, the longest soft ray reaching base of first soft ray of anal. 



Scales on upper and lower parts of body very small, those on mid- 

 dle of sides conspicuously enlarged. Entire head, including maxillary, 

 mandible, gular and branchiostegal membranes wholly covered with 

 spiny scales. Dorsal and anal fins in a sheath. All spines rough- 

 serrate. 



Color in spirits : Light olive, with four dark cross-bars on sides 

 wider than the interspaces, the last one on base of caudal peduncle. 

 Yerticle fins dusky, the soft portions more or less speckled. Ventrals 

 black. Pectorals pale. 



19. Lutjanus viridis Valenciennes. 



A single young specimen, 1^ inches long, showing coloration of adult, 

 the blue streaks being well marked. It agrees with all the characters 

 ascribed to viridis, except the notched preopercle, the spines next the 

 angle being all laigely developed, and the margin of the bone showing 

 no notch for the reception of an interopercular knob. This is doubt- 

 less due to the immaturity of the specimen. 



20. Apogon dovii Giiuther. 



One very young specimen from Station 2797. 



21. Upeneus grandisquamis Gill. 

 Stations 2795 and 2797. 



22. BoUmannia chlamydes Jordau. 



Stations 2799 and 2800. Agreeing well with the original descrip- 

 tion, having 15 rays in the soft dorsal, and the black spot on spinous 

 dorsal very distinct, ocellated posteriorly with white. 



23. Tyntlastes brevis Giinther. 



Two half-digested specimens, said to have been taken from the stomach 

 of a Centropomus at Panama. The dorsal formula is apparently YIII, 

 14, and the head 4^ in length. The teeth are long, wide-set, in a single 

 series.
