small rounded tubercles, fimbriate hind edge little sinuous; nostrils 

 large, confluent with mouth and separated by thick median frenum; 

 interorbital 2 in head to hind spiracle edge. Spiracle along and be- 

 hind eye, about equals 1% eye diameters. 



Tail 1% in disk length, width between ventrals subequal with 

 mouth, spine 1% in head to hind spiracle edge, inserted about first % 

 in tail below disk ; caudal begins above directly behind spine end, be- 

 low middle of its length on lower surface and width subequal variably 

 with internarial; pectorals form more or less rounded disk, front 

 margins almost straight from snout to broadly rounded outer angles, 

 hind lateral edges convex, form obtuse angles with inner edges; 

 ventral edges convex, angles rounded. 



Rich ochreous yellow above when fresh, sometimes stained with 

 pink toward disk edges. Indefinite brown median dorsal stripe may 

 extend from eyes to dorsal spine. White below, purplish toward 

 edges. Width, 387 mm. (McCuUoch.) 



New South Wales. Apparently differs from the Japanese 

 Urolophus aurantiacus in the dark median dorsal stripe.
