THE SCALES OF SOME QUEENSLAND FISHES.— COCKERELL. 59 
but Iridio lias the apical radii more widely spaced, while Tautogolabrus has 
them almost entirely obsolete. 
The scales of Eupetrichthys are very like those of Ernmeekia venusta 
(Jenkins & Evermann), from the Gulf of California. 
gobiid js. 
Hypseleotris compressus Krefft. Scales about 2^ mm. long and 3-J broad, 
of perfectly typical Gobiid type, with the nucleus subapical, the apical margin 
(except in latinueleate scales) raised and roof-like in outline, &c. The structure 
is as in the Japanese Ctenogobius virgatulus f but the middle of the apical margin 
is less elevated. Gobiid scales, wherever they come from, are very characteristic, 
and very much alike. 
NOTOTHENIID/E. 
Parapercis cylindrica Bloch. Boulenger places this in the Leptoscophke ; 
I follow the labelling of the Queensland Museum. Scales subquadrate, a little 
broadened basally ; length and breadth about 2 mm. ; nucleus not far from apex; 
basal radii about ten, strong, spreading; basal margin weakly scalloped; basal 
circuli very dense: lateral circuli much fewer and coarser; apical teeth large 
and sharp ; subapical ctenoid elements well defined, broader than long, about 
four rows distinct. 
It is a singular thing, that the ctenoid features of this scale, including the 
submarginal elements, exactly agree with those of certain Percidae, as for example 
Iladropterus peltatus, from North Carolina. The whole scale is, in fact, very like 
that of Percidre. On the other hand, the scales of Parapercis are not very 
unlike those of the Scorpienid genus Scbastodes, from California. 
It will be seen from all of the above, that the scales of Southern fishes 
closely resemble those of their Northern relatives. On the w r hole, the present 
paper serves strongly to confirm the validity of scale characters, showing that 
family and generic characters hold good over the world.
