shading tltrough the sides to the pearly white of tlie. breast and abdomen; the 
supplementary bars have disappeared and the principal bands have faded to

become dull blue and there is a similar blotch on the opercle, the black tips

Described from fimr (^iieensland examples, measuring 353, 323, 261, and 
124 millimeters, the largest, from IMoreton Bay, belonging to the Amateur Fisher-

VcDiacular vanics : — As both of the names, by Aviiich this species is com- 
monly known, refer to the coloration of the young fish only, Ave have found it 
necessary to create a name, Avhich Avill be suitable to the fish at all stages of 
groAA’th. 
flisiorivdl : — This beautiful species Avas originally described from specimens 
nl)tained at Jeddah, on the Arabian Coast of the Red Sea, by Forskal, to Avhom 
it Avas knoAA’n by the Arab name rimA'' Avhich. according to Valenciennes, signilles 
a staircase, and was doublless suggested by th(‘ evenl^' graded bands on the sides 
of the tish. The next knoAvhalge of imiiortance came from Commcrgon. Avho left 
in his 51S)S. a detailed (h'seri])tion as well as a figure, botii of Avhich Avere sub- 
seipieiitly published by Lacepede ; his specimens, two in number, were taken at 
Mauritius, wlau'e he left the eldm* Bougainville, wlien im his Avay back to France 
after circumnavigating the globe in the frigate 'MIoudeuse,'’ 1766 to 1769. 
Russell’s figure, |)ublished a year later than Lacepede ’s from an example captured 
on the East Coast of India, does little credit to the artist and Avould be irrecognis- 
able Avere it not for the cross-bands.'”' Valenciennes adds little to our knowledge 
iinaiae to consult Forskal 's work i can not tell whether that author doscriljed 
the si:)ecics twice — as Scomber rim a.nd S. speciosus — as would appear fi’om the synonymy 
given by Jordan and Kverinann. Ko nieiition is made of any such species by Glintlier or Bay, 
and I, therefore, follow Valenciennes in looking u])on rim as an Arabic title only. 
^'■'Russell himself conijilicates matters by giving Avrong measurements for his specimen, 
which, he says, was seven in. in length and three and one third in width {i.e. depth). The- 
latter figure is doubtless a misprint for two and one third.
