36 MEMOIRS OF THE QUEENSLAND MUSEUM. 



These scales are wholly of a Clupeid type. Those of Konosirus thrissa 

 (Philippine Is., U. S. Nat. Mus., 56105) differ conspicuously, having a single 

 rather wavy transverse radius crossing the scale a little above the middle, 

 and mere rudiments of radii at the sides below the middle, especially near 

 the laterobasal corners. Above the transverse radius, close to the edge of the 

 area covered by circuli, is a coarse irregular malleation. The scales are 

 larger than those of Dorosoma come, and much broader than long. 



CLUPEID^E. 



Sardinella moluccensis Bleeker. Darnley Island. Scales about 5£ mm. 

 broad and 4^ long; middle of base more or less prominently but obtusely 

 lobed ; circuli and radii wholly transverse ; radii five, entire in normal scales, 

 the lowermost arched upward; apical field thin, free from circuli; apical 

 margin produced into numerous long parallel-sided strap-like teeth. Readily 

 known from S. numeralis (Tampa, Florida) by the conspicuously toothed 

 apical margin. 



Harengula castelnaui Ogilby. Queensland. Scales about 7 mm. broad 

 and 6^ long; basal outline gently convex; circuli and radii wholly transverse; 

 radii four, or sometimes three, usually all entire; apical margin not dentate. 

 Known from H. perforata by the absence of perforations in the apical area, 

 and the somewhat smaller number of radii. 



Amblygaster neopilchardus Steindachner. Queensland. Scales about 

 7-J mm. long and 7 broad, oblique, so that one of the laterobasal angles is 

 very obtuse; basal margin almost straight or feebly lobed; circuli and radii 

 (except the evanescent apical ones) all transverse; radii 6 or 7, all but the 

 uppermost broadly interrupted in middle, the lower ones with the inner half 

 strongly oblique; the thin apical field with numerous fine and weak parallel 

 radial lines, all running upwards, and causing the margin to be subdentate. 



Stolephorus robustus Ogilby. Queensland. Scales about 4| mm. broad 

 and a little over 3 long ; basal margin very obtusely angulate in middle ; apical 

 field thin as usual, the margin coarsely and irregularly dentate, or rather 

 crenulate, the teeth being short and obtuse ; radii and circuli all transverse, 

 the radii two or three, entire, the lowermost angulate in middle. There are 

 frequently rudiments of radii. Compared with S. brownii (Cape Sable Creek) 

 these scales are smaller, and much broader in proportion to their length, 

 while the radii of S. brownii are much more developed, including vertical basal 

 ones, and angular or zigzag ones in the apical field. S. brownii also has a 

 double system of circuli, though the basal ones are much more transverse than 

 those of Engraulis antipodum. According to the scales, antipodum and brownii 

 should be congeneric, while 8. robustus stands apart.
