DISCOVERY REPORTS 



S. dobula is identical with S. porosa. S. punctata (Schneider), of which S. bilineata 

 (Hutton) is a synonym, is very closely related. S. brama (Giinther), from Australia and 

 New Zealand, has a deeper body and only 27 to 31 soft rays in the dorsal fin. Other 

 species of Seriolella are: S. violacea, Guichenot, from Chile; S. amplus, Griffin, from 

 New Zealand; S. velaini, Sauvage, from the Island of St Paul; and S. antarctica 

 (Carmichael), from Tristan da Cunha. 1

Depth of body 2f to 2f in the length, length of head 3 1 to 33. Snout as long as or 

 a little shorter than eye, diameter of which is 3I to 4 in length of head; interorbital 

 width about 3 \. Maxillary more or less exposed, extending to below anterior part of 

 eye. Operculum, suboperculum and interoperculum scaled ; margin of praeoperculum 

 feebly denticulated. About 14 gill-rakers on lower part of anterior arch. About 

 95 scales in the lateral line, which does not become straight until it reaches the caudal 

 peduncle. Dorsal VIII-IX 3i-32(?). Anal III 20-21 (?). Pectoral as long as or nearly

as long as head ; pelvics inserted distinctly behind pectorals, length about twice in that 

 of head.

It is with some doubt that I have identified these specimens with Guichenot's 

 species, as the original description is a poor one and Mr Chabanaud informs me that 

 the type is not to be found in the Paris Museum. Regan (1902, Ann. Mag. Nat. Hist., 

 Ser. 7, x, p. 128) has suggested that this species does not belong to the genus Seriolella, 

 "and may be a Liriis". 



1 I am greatly indebted to Mr P. Chabanaud for photographs of the type specimens of S. porosa and 

 S. violacea in the Paris Museum.
