 Acanthias megalops, Macleay, Proc. Linn. Soc. N. S. Wales, vi. 1881, 



p. 367.

fig. 2. 



Hab. Southern Australia ; Tasmania. 



In the British Museum five specimens, 400 to 530 mm. in 

 total length. 



A stuffed specimen of 900 mm. from Juan Fernandez 

 evidently represents the Spinax fernandezianus of Guichenot 

 (Gay, Hist. Chile, Zool. ii. p. 365 (1848); Acanthias fernan- 

 dezianus, Philippi, An. Univ. Chile, lxxi. 1887, p. 559, pl.iv. 

 fig. 3). This Chilian species may, perhaps, be different from 

 S. megalops, but I am unable to give any distinctive cha- 

 racters. Ribeiro has described a Squalus from Rio Janeiro 

 as S. blainvillii (Arch. Mus. Rio Janeiro, xiv. 1907, p. 168); 

 this may be S. fernandezianus.
