A REVISION OF THE AUSTRALIAN ORECTOLOBIDA. 275 
posterior angle obtusely pointed, the hinder border linear, 
as long as the spiracle, and 2°00 in the basal length, which 
is equal to the vertical height of the fin; second dorsal 
similar to and scarcely smaller than the first, its distance 
from the origin of which is 2°20 in that from the tip of the 
tail; interdorsal space 1°65 in the base of the first dorsal 
and 1°10 times the distance between the second and the 
anal. Height of anal fin 1°75 in its basal length, which is 
3°40 in its distance from the ventral. Caudal fin 4°40 in 
the total length. Pectoral fin tetragonal, originating 
slightly nearer to the tip of the snout than to the ventral; 
anterior border convex, posterior concave, outer linear with 
rounded angles; base of pectoral 1°30 in its greatest width 
and 1°80 in its length, which is 1°35 in the length of the 
head and 1°55 in the distance between its origin and the 
ventral. Origin of ventral fin two-fifths nearer to the first 
dorsal than to the pectoral, its width 1°35 in its length, 
which is 1°65 in the head. Skin distinctly rough, the tips 
of the carinee forming appreciable spines. Dark sandy, 
with numerous diversely shaped lilac ocelli and a few 
inconspicuous darker transverse bands; lower surface 
cream colour. Fins similar to the adjacent parts of the 
body, mostly pale edged and with the lilac markings simple. 
(maculatus, spotted). 
Length of largest specimen seen by us 1090 mm. Coasts 
of Tasmania, South-eastern and Hastern Australia. All 
previous writers having confused this species with the 
succeeding, it is impossible to fix accurately the exact 
limits ofits range. Described from a female fetus 212 mm. 
long, in which the yolk-sac was fully absorbed, taken from 
a specimen captured at Woody Point, Moreton Bay, and 
presented to the Amateur Fishermen’s Association of 
Queensland by Mr. J. T. Jameson; Cat. No. 388. 
We have compared nine examples of O. maculatus with 
seven of the following species, O. ornatus, and find that
