Large teeth appear to have only basal cusp, and in very large teeth 

 the cusps, though present, are not such a distinctive feature. Outer 

 row of upper teeth almost straight and slope outward. The next 

 upper row more twisted and slope more obliquely inward. Lower 

 teeth 3 rows in front, all twisted in varying degrees toward upper 

 row. Some few small teeth with 2 basal cusps on each side at base. 



Dorsal origin just behind pectoral base. Second dorsal origin 

 over hind part of anal base and farther back than in Lamna nasus. 

 Pectoral base slopes obliquely downward. 



Dull slaty on back and sides becoming lighter below, where general 

 color seems rather light yellow, perhaps tinged with red. Eye deep 

 green. (Phillipps.) 



New Zealand. Said to have similar dentition to Lamna nasus, also 

 the second dorsal originating over the anal, and the body stout. It 

 agrees also with hums tigrls in the position of its first dorsal and 

 the length of its lower caudal lobe.
