ECHIOSTOMA BARBATUM.

Stomias barhatus, Cuv. R. An. ii. 283, 284 1 



This is very probably the fish briefly noticed by Cuvier under the 

 above synonym. But it seems, at all events, sufliciently distinct 

 generically from the Esox or Stomias Boa of Risso (Hist. iii. 440. 

 f. 40), with which Cuvier associates it; but which, besides having 

 other differences indicative of generic distinction, is figured by Risso 

 as covered with large scales, like a Microstoma or ChauUodus. Nor 

 can I find any trace of the Madeiran fish in Risso*, or in any other 

 work to which I have access. It may therefore be considered one 

 of no less rarity than singularity of characters and aspect ; linking 

 the Esocidae with the Murcenidce, and indeed partaking more of the 

 habit, form and colouring of the latter tribe than of the former. 



A single example only has been taken in a net close in shore, 

 measuring thirteen inches and a quarter long. It was wholly devoid 

 of silver spots but had two rather conspicuous rows of pale pore- 

 like dots low down on the sides, and a most singular rose-coloured, 

 pear-shaped spot, placed obliquely beneath and a little behind the 

 eye, at the bottom of the cheek. This soon faded to white in 

 spirits. The whole body was an uniform dark chocolate-brown, 

 punctate with black dots disposed in bands or figures. The single 

 beard is thick or broad and subcartilaginous, equalling in length the 

 depth of the head. The opercles are of the usual strength and 

 structure. 



Fam. Salmonid^e. 

 Gen. AuLOPUs, Cuv. 



Saurus Lacerta (Risso), Syn. p. 188, is certainly an Aulopus ; and 

 notwithstanding the larger number (15-17) of its branchial rays, 

 is also probably the A. filament osus of Cuvier (Reg. An. xi. 315). 



* Cuvier speaks of his Stomias barhatus being equally with Stomias Boa 

 a discovery of M. Risso's ; but I can find no trace of the former fish in his 

 ' Histoire,' or, as Cuvier cites it, the second edition of his ' Ichthyology.'
