 edge, nearly equals orbit. 



Whole upper surface of disk, including ventrals and tail, all sui"- 

 faces of posterior half of tail including dorsals and rudimentary 

 caudal, covered with small, sharp, close set prickles; large spine at 

 each angle of each orbit, pair between spiracles, 1 or 2 on each shoul- 

 der girdle each side center of disk and single row down middle of 

 back from occiput nearly to first dorsal fin; under surface of disk 

 smooth and glandular. 



Dorsals adjacent, separate, posterior larger or about 2 in head to 

 spiracle, interdorsal very narrow notch; pectorals form rhomboidal 

 disk, angles rounded, front edges slightly and broadly sinuous.

 pt. 5, p. 11, pi. 22, fig. 1, 1923 (type locality: Natal coa.st, in 470 fathoms).— 

 Barnard, Ann. South African Mus., vol. 21, pt. 1, p. 69, 1925 (Natal coast). 



Head to spiracle 6% in total ; disk length II/3 its width, 21/3 in tail. 

 Snout liy4 in head measured to spiracle, front edges almost straight 

 and meet at acute angle ; eye 5 in head to spiracle, 4% in snout, 2'/^ 

 in interorbital ; mouth nearly straight, 21/3 in preoral length; teeth 

 in numerous rows, rhombic based and slightly denticulate ; outer nos- 

 tril edges with funnel-shaped flaps and slight fringed flaps cover 

 moiith corners; interorbital 2% in head to spiracle, flat. Spiracles 

 small, oblique, close behind eyes, smaller than eyes. 



Whole upper surface, including sides of tail, covered with small 

 spines; under surface smooth; stellate based spine before each orbit 

 and 2 behind; row of equally large median spines from behind head 

 to tail to first dorsal; 2 suprascapular spines on each shoulder, 1 large 

 and other small. 



Dorsals separate, small, pointed, first little larger or 1% in snout; 

 caudal minute; pectorals form quadrangular to rhombic disk, front 

 margins nearly straight, outer angles, posterior margins and angles 

 broadly rounded; ventrals pointed posteriorly and notched about to 

 middle. 



Reddish brown. Dorsals, caudal, and lateral folds deep reddish 

 brown. Under surface as above, except areas around mouth and 

 abdomen, which white. Tail below like body. Length, 232 mm.
