A papilliform j^rojection above the posterior part of each eye. 

 Nasal cirrus long, simple. On each side a small simple dermal 

 lobe above the upper lip, a larger one at the angle of the mouth, 

 and a third at the side of the head. First dorsal originating a 

 little in advance of the posterior end of base of pelvics ; free edge 

 of the fin straight or convex, posterior angle rounded or obtusely 

 pointed ; length of base considerably more than the distance 

 from second dorsal, which terminates nearly above the origin of 

 anal. Pectoral extending |-f of the distance from its origin 

 to that of the pelvics. Yellowish, back greyish ; on the back,, 

 in front of the first dorsal fin, three large dark areas edged with 

 white, continuous or subcontinuous with dark vertical bars on 

 the sides ; tail completely encircled by 3 dark vertical bands, 

 corresponding to the two dorsal and the anal fins ; fins with large 

 dark spots.

Crossorhinus (part.) Glinth. Cat. Fish. viii. p. 413 (1870). 



Yery closely allied to Orectolobus, but with broader and more 

 depressed head, smaller eyes, and wider spiracles than in any 

 species of that genus. No longitudinal fold below the eye. 

 Gill-openings rather small and of equal width, equidistant ; last 

 four above the base of pectoral.

Nasal cirrus ramose. Head margined by a nearly continuous 

 series of ramose dermal flaps, extending on each side from the 

 nasal opening to the pectoral fin ; a transverse series of similar 

 flaps behind the mouth. First dorsal originating slightly in 

 advance of the posterior end of base of pelvics ; free edge of the 

 fin straight or slightly convex, angles rounded ; length of base 

 scarcely more than the distance from second dorsal, which ter- 

 minates above the origin of anal. Pectoral extending 4 of the 

 distance from its origin to that of the pelvics. Upper parts of 

 head, body, and fins covered with a brownish network enclosing 

 small round whitish spots ; a few small dark spots on the tail, 

 2 or 3 on each of the pectoral and ventral fins, one on each side:-
