Head to hind spiracle edge 4% in total length. Snout II/2 in head 

 to hind spiracle length, as seen above forms broad obtuse angle with 

 very short point ; eye 4%, 3 in snout, 1% in interorbital ; mouth width 

 2%; 2 or more papillae on median line of mouth behind lower jaw 

 and several others widely spaced on either side; internarial 2%, hind 

 outer angles of valve forms small rounded tubercles, hind edge fimbri- 

 ate; nostrils large, narrow, without skinny lobe posteriorly; inter- 

 orbital 2%. Spiracle along and behind eye, length 3%. 



Tail depressed, with narrow keel on either side, length 1% in disk 

 length, width between ventrals subequal to that of mouth; spine in- 

 serted slightly before middle in tail length, II/2 iii head to hind spi- 

 racle edge, without dorsal fin; caudal narrow, width less than inter- 

 narial, begins below spijie end on upper surface of tail and extends 

 farther forward below; pectorals form widely rounded disk, length 

 1% its width, front edges nearly straight to rounded outer angles and 

 hind edges feebly convex and form obtuse angles at junctions with 

 inner edges ; ventrals subquadrangular, angles rounded. 



Drab gray above, with 2 faint plumbeous cross bars on hinder part 

 of head and oblique bar on either side of disk anteriorly. Width, 

 208 mm. (McCulloch.) 



Great Australian Bight. Said to differ from Urolophus haiamfos 

 in the variegated color pattern, though as this is described from 

 formalin material in the above species, this character requires 

 confirmation.
