H eftranchus Gray, List Fish. Brit. Mus., Chondropt., 1851 : 68, equivalent to Heftranchias Rafinesque, 1810. 

 Heftrancus Costa, Fauna Napoli Pesci, 3, Chondropt., 1854-57: 5 (29), equivalent to Heftranchias Rafi- 

 nesque, 1 8 10. 

 Hexanchus (in part) Seabra, Bull. Soc. Portug. Sci. nat., 5, 191 1 : 195. 



Generic Characters. Seven gill openings, decreasing in length from front to rear; 

 snout narrow, tapering; horizontal diameter of eye considerably greater than distance 

 between nostrils. Characters otherwise those of the suborder and family. 



Range. Eastern and western North Atlantic, South Africa, Australia, Japan. 



Species. Our own comparison of medium-aged and small specimens from Japan, with 

 others from Cuba and from the Mediterranean (see Study Material, p. 88) corroborates 

 GarmanV conclusion that the North Pacific representative of the genus is identical specifi- 

 cally with the Atlantic form; such differences in proportionate dimensions as exist between 

 them are no greater than might have resulted from the fact that the larger of the Japanese 

 examples had been dried. However, the Australian form may be distinct, as indicated in the 

 following key.''

I. Heptranchias hasiuelti Ogilby (Proc. Linn. Soc. N. S. W., 22, 1897: 62), Nolidanus medinae and N. wolnicziyi 

 Philippi (An. Univ. Chile, 109, 1901 : 305, 307, Chile), and A', ferox Perez Canto (Estud. Escual. Chile, 1886: 

 7), which are included by Fowler (Bull. U.S. nat. Mus., too [/j], 1941 : 9) in the synonymy of Heftranchias 

 ferlo, all appear, from the original accounts, to fall in the genus N otorynchus.
