Disk subcircular, outline broken only by notch under tail. Tail 

 short, with slight lateral fold each side. Eyes not distinct. Teeth in 

 front part of jaws, pavementlike, hind series with sharp cusps. 

 Spiracles with entire edges. Body naked. Dorsal fin single. Front 

 part of ventrals modified for walking; hind part coalesced with pec- 

 torals to form hinder disk edge. 



New Zealand. Differs from Narke in the absence of functional 

 eyes, circular disk, short tail and the ventrals coalesced with the disk.

Head to hind spiracle edge 7V^ in total length. Eye minute, white 

 spot close before each spiracle; mouth narrow, protractile in fold of 

 skin; lips extremely fleshy, upper divided in midline by an apparent 

 space ; lower lip very deep, sides of median fissure close together, each 

 forming ridge where approximating; teeth form small pavementlike 

 plate confined to front of each jaw ; hind angle of each tooth produced 

 slightly on anterior series, increasingly so backward until in hinder 

 teeth sharp cusp developed; nostrils close together, covered by com- 

 mon subquadrangular valve; spiracles well developed, interspiracle 

 space 2% to end of snout. Gill openings in subparallel series. 



Dorsal origin little before hind disk edge, length % greater than 

 base, latter equals interspiracle width between outer spiracle edges; 

 caudal 4% in rest of body length, rounded ; tail 2^^ ; pectorals form 

 circular disk, about long as wide ; ventrals advanced, widely separated, 

 directed almost at right angles or horizontally to body axis, front 

 edges and rounded extremities covered with thick skin, attached pos- 

 teriorly far within disk margin, horizontal length of each equals their 

 distance apart; claspers small, not reaching hind disk edge. 



Coffee-brown above, pale brown beneath, darker round disk margin. 

 Mouth parts and ventral edges yellow. Length, 375 mm. (Waite.) 



New Zealand, in depth to 102 fathoms.
