SEnSION OF AUSTEALIAN THEBAPONS.—OGILBT AND McCULLOCE. 105 



the Australian s]3ecimens agree with Japanese examples in their color-marking and 

 scale-coiuits, and are therefore identical with T. servus Bloch, wliich was originally 

 described from Jaj^an.

Type localities : — Fitzroy River near Rockhampton, M.Q. {T. percoides). 

 Port Jackson, N.S.W., by a mistake (D. /a5ci«to). 

 Swan River, W.A. {T. fasciatus). 

 Fitzroy River, probably {T. terrce-regince). 

 Queensland {T. spinosior). 



Bod}^ ovate to subovate, the dorsal contour considerably more arched than 

 the ventral, its width 1-9 to 2-33 in its depth, which is 2-25 to 2-65 in its length and 

 from one fifth to four ninths longer than the head ; caudal peduncle usually a little 

 longer than deep, its least depth 7-5 to 8-33 in the bodj^ length. Head about two 

 ninths longer than deep, its upper profile linear or feebly rounded to above the posterior 

 third of the eye, beyond which it merges into the oecipito-nuchal convexity, its width 

 1-4 to 2 in its length, which is 3 to 3-33 in that of the body. Snout obtuse and narrowly 

 rounded anteriorly, its length 2-8 to 3-35 in that of the head. Eye large, its cUameter 

 from one seventh more to two ninths less than the length of the snout and 1-25 to 1-5 

 in that of the postorbital head ; interorbital region flat or feebly convex, its width 

 1-1 to 1-5 in the length of the snout. Maxillary not extending to the vertical from the 

 anterior border of the eye. Preorbital strongly denticulated in the young, becoming 

 rugose or even smooth in the adult; preopercle broadly rounded, the angle rather 

 coarsely serrated, the serrse decreasing in size on the hinder limb and disappearing on 

 the lower ; opercle with two flat spines, the lower the longer ; post-clavicle strongly 

 denticulated ; humeral concealed. 



Jaws ^\itll a band of villiform teeth and an outer series of much enlarged conical 

 approximate movable teeth, the tips of which are recurved ; they decrease in size 

 gradual^ from the front so that some of the posterior ones scarcel}^ exceed or equal the 

 inner teeth ; tips of all the teeth chestnut-brown. 



Scales in 40 to 42 (37 to 43) series above the lateral line, and 33-39 below it ; 

 6, rarely 7,/l/14 or 15 scales in the series extending obhquely backwards from the base
