Proportions of two specimens 122 and 262 mm. long. Depth 2-6-2-7 in the 

 lengtli to the hypural joint ; head 2-7 in the same. Eye 3-3-4-3 in the head, shorter 

 than the snout, and greater than the interorbital width. 8nout 2-5-2-8, interorbital 

 space 4-8-5-2 in the head. Fifth dorsal spine 1-4-1-7, first dorsal ray 1-0-1-7, second 

 anal spine 1-4- 1-9, and first anal ray 1-5 in the head. 



Body elevated, compressed. Snout sharply pointed, the upper jaAv the longer ; 

 the profile from its tip to the first dorsal spine is almost straight or slightly convex 

 on the najie. Interorbital and cranial ridges well developed in the young, obsolete 

 in adults. Preorbital Ijone serrated. Preoperculum more or less denticidate, the 

 denticles enlarged on the rounded angle in young specimens. Lower opercular spine 

 not produced beyond the opercular lobe. Suprascapular and coracoid bones exposed 

 and more or less denticulate. Dorsal and anal spines very long and strong. The 

 fifth dorsal spine is the longest, much longer than the rays in the young, subequal 

 to them in adults ; eleventh and tAvelfth spines subecpial. or the last slightly the 

 longer : soft dorsal rounded. Second anal spine longer than the third, as long as the 

 raA^s in the young, shorter in adults : soft anal angular. 



Color in alcohol : — Uniform dusky silver ; the fin-membranes arc somewhat 

 darker, the anterior and ])osterior anal rays white. In the young there are three 

 narrow longitudinal dark bars on the sides. 



The above diagnosis is based on eight specimens 105-262 mm. long from 

 various localities. 



Remarks : — The typical specimens of Therapon nasutus Macleay are in the 

 Australian Museum collection; they do not differ from the descriptions and illustrations 

 of T. argenteus quoted above. Therapon chalybeits was also based on a young example 

 of Cuvier and Valenciemies' species ; the t^^iical specimen, wliich is preserved in 

 the Australian Museum, proves the proportions given by Macleay to be incorrect 

 in sevei^al details. A young specimen from Queensland, received l)y the Australian 

 Museum from the Queensland Musevnn in 1886, agrees verj^ well with de Vis' descrip- 

 tion of his T. acutirostris, and is possibly a co-tiy'pe of that species ; it is also identical 

 with T. argenteus. 



Logs. : — We have examined specimens from the following localities : — Port 

 Moresby, Papua ; Normanby Island, D'Entrecasteaux Group, in fresh water ; Santo 

 and Eromanga, New Hebrides ; Queensland. 



THERAPON CARBO sp. nov. 



(Plate XII, fig. 1.) 



ROUND-TAILED GRUNTER. 



Type locality : — Gregory River, N.Q. 



Body ovate, the dorsal contour scarcely more arched than the ventral, its 

 width 2 to 2 T in its depth, which is 2-3 to 2-4 in its length and one fourth more than 

 the length of the head ; caudal peduncle dee])er than long, its least depth 7-25 to 7-33 

 in the body-length. Head about one fourth longer than deep, its upper jirofile linear 

 to above the hinder border of the eye, beyond which it merges into the occipito- 

 nuchal convexity, its width 1-67 in. its length, which is 2-85 to 3 in that of the head. 

 Snout rather sharp and narrowly rounded in front,, its length 3 to 3-15 in that of the 

 head ; lips rather thin. Eye moderate, its diameter 1-33 to 1-5 in the snout and 2 to 

 2-2 in the postorbital head ; interorbital region feebly convex, its width but little 

 less than the length of the snout. Maxillary extending to below the posterior nostril.
