88 DESCRIPTION OF NEW QUEENSLAND FISHES 
feeding at the bottom and were accompanied by droves 
of sharks (Carcharias melanopterus), numbers of which were 
captured. 
From an examination of several specimens I find that 
de Vis’ Crossorhinus ornatus is a valid species closely allied 
to Orectolobus japonicus, Regan. Its correct title is 
Orectolobus ornatus. 
SCOLIODON JORDANI sp. nov. 
Slender Dog-shark. 
Body slender and subfusiform, its width { of its depth, 
which is 102 in the total length. Head strongly depressed, 
its depth immediately in front of the gill-slits 14 in its width, 
which is 2} in its length. Length of head 13 in that of the 
trunk and } of the total length. Snout produced and 
pointed, its length 25 in that of the head. Space between 
the outer angles of the nostrils a little more than that 
between the inner angle and the tip of the snout, which is 
13 time its distance from the mouth; internasal space 
1, in the width of the mouth, which is but little (4) more 
than its ramal length, + of the length of the snout, and 3g 
in that of the head ; tip of mandible rounded, not extending 
forward to the level of the anterior border of the eye ; outer 
labial groove very short, directed outwards at a right angle 
to the jaw and + of the space between the eye and the 
mouth ; no inner groove. Eye a little nearer to the first 
gill-slit than to the extremity of the snout, its longitudinal 
diameter 4 of the length of the head. Interorbital region 
convex, its width 2,°, in the length of the head. Branchial 
region 1% time the diameter of the eye; gill-slits narrow, 
the 5th 2 of the Ist and 2? of the 4th, which is the widest 
though not so wide as the eye. Length of head and trunk 
about 1, in that of the tail. First dorsal fin inserted much 
nearer to the ventral than to the pectoral, its distance 
from the tip of the snout rather more than 4 of the total 
length ; anterior border of fin undulose, its outer angle 
rather sharply rounded ; outer border vertical in front, 
deeply emarginate behind, its posterior angle produced and 
acutely pointed, not quite reaching to the vertical from the 
origin of the ventral; length of hinder border rather less 
than half the base, which is 1} in the vertical height of the
