REVISION OF JUSTILILIAN TEEEAPONS.—OGILBY AND McCULLOCIT. ]21 



two spines, the lower strong, but not extending beyond the opercular lobe. Teeth in 

 a band in each jaw, the outer ones largest, cylindrical, and fixed ; vomer and palatines 

 toothless. Gill-rakcrs of the first gill-arch rather short and thick posteriorly, about 

 twelve on the lower limb. 



Scales largest on the anterior portion of the sides, smallest on the caudal 

 jjeduncle and anterior to the ventrals. 



Dorsal spines moderately strong, the fifth the longest but shorter than the 

 anterior rays ; last spine a little shorter than the penultimate one : soft dorsal rounded. 

 Anal originating below the posterior dorsal spines and terminating slightly in advance 

 of the soft dorsal : the spines are rather strong, the second a little longer than the third, 

 and much shorter than the ra\^s ; soft anal rounded. Pectoral pointed above, the 

 hinder margin rounded ; fourth or fifth upper ray longest. Ventrals inserted below 

 the origin of the dorsal in the young, farther back in adults, and reaching back to the 

 vent or to the anal fin ; anterior ray with a short filament. Caudal emarginate. 



The color-markings are indistinct in most of the specimens, and are clearly 

 shown in only one small example. This has eight rather broad dark bands on either 

 side, those above the lateral line following the curve of the back and being more or 

 less confluent posteriorl3^ while those below it are horizontal. The median band 

 terminates in a dark mark on the base of the caudal, above and below which are two 

 dark rounded spots ; another spot on the upper margin of the caudal peduncle. Some 

 specimens have the outer portions of the dorsal and anal fins light-colored, while the 

 membranes of the spinous dorsal and anal bear darker markings. There is a light 

 curved band at the base of the pectoral, and the opercular membrane is blackish 

 posteriorly. 



Described from three specimens, 94-200 mm. long, the largest and smallest 

 being two of the typical specimens, and the other a Queensland example. The figure 

 is prepared from the latter, but the color-marking is copied from one of Macleay's 

 smaller specimens. 



Loc. : — Goldie River, New Guinea ; fresh water. York Peninsula, Queensland ; 

 this locality is uncertain and requires verification.

D. xiii 11-12 ; A. iii 9-10 ; V. i 5 ; P. 15-17 ; C. 17. 59-67 series of scales between 

 the origin of the lateral line and the hypural joint counted below the lateral line, and 

 63-71 above it ; 10-11 J between the lateral line and the middle of the spinous dorsal. 

 Cheek-scales in about six rows. 



Depth 2-2-2-S in the length to the hypural joint ; head 3-1-3-2 in the same. 

 Eye 4-5-5-1 in the head, and 1-2-1 -5 in the snout, which is 3-2-3-7 in the head. Inter- 

 orbital width 3-3-5, depth of caudal peduncle 2-4-2-5 in the head. Sixth dorsal spine 

 1-7-1-8, second dorsal ray 2-1, second anal spine 1-8-2-2 ; and second anal ray 1-6-1-9 

 in the head. Pectoral fin 1-4, first ventral ray 1-3 in the head. 



Body moderately deep, compressed. Head small, its upper profile rising very 

 obliquely from the snout to the dorsal fin, straight or a little convex on the nuchal 

 region. Interorbital space flat or slightly convex. Snout obtusely pointed, jaws
