SCYLIORHINIDAE 9 



about 6 in the distance from tip of snout to first gill-opening, there are generally two series 

 of tubercles on the back from the head to the first dorsal fin, and the nasal flaps have 

 a different shape. The exact range of S. chilensis is doubtful, but it probably does not 

 extend southwards into the Patagonian region as here defined. The British Museum 

 has received nine examples of this species from Lota, through Mr V. Cavendish 

 Bentinck.

 otter trawl, 82-81 m.: 1 male specimen, 600 mm. 



Very closely allied to S. acanthias of the North Atlantic and Mediterranean, but with 

 a shorter snout, the praeoral length equal to or less than the distance from eye to first 

 gill-opening, the praeocular length about equal to the distance from anterior edge of 

 eye to spiracle. Dorsal fin-spines longer, and pale spots on body larger than in 

 S. acanthias. 



Hab. Southern Australia and Tasmania; New Zealand; Argentina, Patagonia and 

 Chile. 



I have compared the above specimen with 3 (550-800 mm.) from Tasmania and a 

 male specimen (760 mm.) of S. kirkii received from Mr W. J. Phillipps and am unable
