Transactions and proceedings and report of the Philosophical Society of Adelaide, South Australia . to the nape almost straight and thence slightly archedto the dorsal fin. Interorbital space almost flat; a few obtusebony ridges on the posterior part of the cranium. Upperjaw slightly longer than the lower; maxillary reaching tobelow the hinder nostril, its posterior margin obliquely trun-cate and exposed. Eye rather small, much shorter than thesnout, which is a little longer than the interorbital separated by a space equal to their own diameter,with free cutaneous margins. Preorbital bone denticulateposteriorly. Preoperculum evenly denticulate, the denticleslargest on the rounded angle. Operculum with two spines,the lower of which is the longer, and attains the margin ofthe opercular lobe. Suprascapular and coracoid bones ex-posed, and weakly denticulate. Each jaw with a band of minute teeth, the outer onesslightly enlarged, subcardiform, and slightly and palatines toothless. Scales largest on the anteriorportion of the sides, smallest on the Fig. 1. Dorsal spines rather slender, the fifth longest, and thefollowing decreasing backward to the last. Second anal spinemuch longer and stronger than the third, but shorter thanthe anterior rays. Pectoral obtusely pointed above, the fifthupper ray longest. Ventral inserted just before the verticalof the first dorsal spine, and reaching about half its distancefrom the vent. The caudal is much damaged, and the softportions of the dorsal and anal are so firmly adpressed thattheir exact form cannot be satisfactorily determined. Thefirst dorsal spine also is lacking. Colour.—Apparently olive-green above and silvery below,the base of each scale with a small dark spot which combineswith its fellows to form indefinite rows along the scale without definite markings. 474 Described from a specimen 206 mm. long from the snoutto the hypural joint. It is allied to T, hidyana, but is
