A REVISION OF THE AUSTRALIAN ORECTOLOBIDA. UII 
by Saville-Kent,' and find that they do not differ from those 
of the other species, the last being the largest, and the last 
two closer together than the others. 
The Wobbegongs or Carpet Sharks’ are ovoviviparous 
ground sharks of sluggish habits, frequenting the neigh- 
bourhood of the shore, where they lie concealed among the 
weed covered rocks. Their beautiful colour patterns, 
harmonious contrasts of varied browns and lilacs, assimilate 
their surroundings so perfectly as to deceive the small 
fishes and crustaceans, which with mollusks, form the bulk 
of their food. The imitation is accentuated by the fringe 
of dermal lobes which adorn the lips and sides of the head, 
and which are not found in any other recent selachian. 
Four of the five known species are Australian, but of 
these good specimens of two only, O. maculatus and O. 
ornatus, are available to us for examination. There are 
skins of the others, O. dasypogon and O. tentaculatus in 
the Australian Museum, and from these the accompanying 
observations and figure have been made. 
a. Nasal cirrus simple; dorsal surface with numerous 
papillee. tentaculatus. 
aa. Nasal cirrus lobed; dorsal surface without papille. 
b. Sides of head with a nearly continuous row of branched 
lobes dasypogon. 
bb. Sides of head with only a few widely spaced lobes. 
ec. Body with large light ocelli. 
d. Lobe of nasal cirrus simple; supra-labial lobes 2 or 3. 
japonicus. 
dd. Lobe of nasal cirrus branched; supra-labial lobes 3 to 
6. maculatus. 
cc. Body marbled with distinct cross-bars; supra-labial 
lobes 2 to 4. ornatus.

7 Occasionally one hears them miscalled ‘‘ Tiger Sharks,” but that 
name properly applies to Galeocerdo tigrinus, which from its strength and 
ferocity fully merits the title.
