the first was uniformly blackish, without spots or marks, thus an- 

 swering to Centrolophus Morio of Lacep^de : the second individual 

 was smaller, and was marked precisely as in MM. Cuvier and 

 Valenciennes' figure (t. 269) of C. pompilus. 



I have no hesitation in uniting both these fishes, with their re- 

 spective synonyms, under the name long since applied by Willoughby 

 to designate the species ; although by him employed especially in 

 reference to the second state or variety abovementioned, which also 

 was the variety originally described by Rondeletius. 



Pompilus Bennettii. 



JLeirus Bennettii, nob. in Cam. Trans. VI. 1, 199, t. V. — Syn.

Centrolophus ovalis, Cuv. and Val. IX. 346. 



crassus. lb. 348. 



The genus Leirus proves identical with Centrolophus, Lac, which 

 in its turn, if not intolerable in itself (see Cuv. and Val. IX. 331.), 

 must yield precedence to the prior claims of Pompilus, Rond. The 

 species described by the Ichthyologist of Montpellier, {Centrolophus 

 pompilus, Auct.) ought, on the other hand, as long ago by Willoughby, 

 to be called Pompilus Rondeletii. 



Brama Raii, Bl. " Freira." — Syn. Mad. Fish, p. 179. 



The true affinities of this fish are most assuredly Scombridal, or 

 to speak more strictly, Coryphsenidal. 



It was in reconsidering those of Brama, and in reaching this con- 

 clusion, that I was first led to detect the true affinities and synonyms 

 of Leirus. It was not till convinced of the necessity of placing 

 Brama next to Pompilus (Centrolophus, Lac), that I discovered Le/rw* 

 Bennettii to be a genuine species of this last-named genus. 



So valuable are these studies of affinities ; and thus do even errors 

 often lead to valuable truth. I was not wrong, however, in asso- 

 ciating Leirus Bennettii vi^ith Brama ; but in not referring sooner it, 

 or rather both, to the neighbourhood of Pompilus.

This is the fish published, in the former part of this list, under the 

 name and with the synonyms of M. Chelo, Cuv. Comparing it, how- 

 ever, more closely with the description of M. Chelo in the eleventh 

 volume of MM. Cuvier and Valenciennes' Histoire, I find the follow- 

 ing principal discrepancies in the Maderan fish :
