Fishes from Tristan da Cunha. 4G7 



Fisclie, p. 90, pi. v. fi^. 1), wlio lias shown that it is not the 

 same as the Chilian form with which Cuvier and Valenciennes 

 (Hist. Nat. Poiss. ix. p. 489) and GUnther (Cat. Fish. iv. 

 p. 81) identified it. 



The second species seems to have escaped the notice of 

 later writers, but there can be little doubt that it belongs to 

 the family Stiomateitlre and that it is rather closely related 

 to Sauva<>e's Seriollella velaini from the Island of 8t. Paul 

 (Arch Zool. Exp. viii. 1879, p. 32, pi. i. fig. 2). 



The third species is a Bovichthys that has recently been 

 rediscovered by the 'Scotia' at Goiigh Island, thus enabl'itij^ 

 me to show its distinctness from the Chilian species with 

 which it had beeii confused. 



The fourth species has just been received for idt^nfification 

 from the Director of the South African Museum, and proves 

 to be a Lahrichthyii. In the original figure the scales on the 

 head are not shown, those on the body are too numerous, and 

 there are other errors ; nevertheless the form, proportions, 

 fin-structure, markings, &c., are given with sufficient accuracy 

 to leave no doubt as to the identity of the species. This may 

 be judged by a comparison with the excellent figure given by 

 Sauvage, who redescribed this form from St. Paul under the 

 name Labrichthys lantzii, but mistook the female for another 

 species, which he called L. isleanus. A description of the 

 specimens from Tristan da Cunha follows.
