No good objection can be offered against this differentiation as it 

 is pertinent and diagnostic, save as to the second spine, which is sim 

 ply the extension of the proscapula and is no more evident in the pike- 

 perches than in the typical perches. Raiinesque's diagnosis is, in fact, 

 better than Cnvier's. 



In 1819, Bosc* defined the names Sandat and Sandre in the following 

 words, neither name being nsed as a scientific or Latin designation of 

 an accepted genns. 



Sandaf. Syuouyuic dc Suiidrc. (B.) 



Sandre. Poisson de uos rivicTes que Linuipus avoit place parmi lea Perches {perca 

 hicioperca), et qne Lac^pcde a porto dans son genre Centropome. Cuvier vieut de le 

 faire servir a Tetablissement d'un sous-genre. Ses caracteres sont : tete dopourvue 

 d'^cailles ; gueule arineo de dents poiutues et ecartees ; des dentelures au pro'oper- 

 cule; des piquaus a I'opercule. 



La Sciene coro et de rile-de-Frauce paroit devoir faire i)art de ce sous-genre. (B). 



In 18l*7, Cloquett defined the genns nnder the head of " Sandre;" 

 gave, as a pseudoscientific equivalent, the name '' Sandat," and de- 

 fined it as follows : 



Sandre, Sandat. (Ichthyol.) ^^. Cuvier a distlngu6 sous ce noni un genre de pois- 

 sons qu'il a s6par6 de celui des Ceiitropomes de Jjacepede, et de celui des Perches de 

 Linnanis. 



This was defined in the following terms: 



Corps uhlong, epais, comi^'hno, ecailleux;; opercnles deutelees sans pi((uans; tete 

 alepidote ; deux nageoires, dents poiutues et ecartees. 



Two species were recognized : 



(1) "Le Sandat, Sandat lHcioperca,'N. [i.e. Cloquet] ; Perca hicioperca Linnaeus," 

 ;=Stizo8tedion hicioperca. 



(2) Xe "Saudre coro, Sandat coro":^^Conodoii nobile. 



In 1828 and 181*9, Bory de Saint Vincent, in the Dictionnaire Clas- 

 sique d'Histoire Naturelle, adopted as a subgeneric name ISandat. 

 Under the head Perche (vol. 13, p. 204) he defined the subgenus: 



+ t t t t Sandre, Sandat. Les Poissons de ce sous-genre, formes aux depens des 

 Centropomes de Lacepede, out des dentelures au preopercule, mais point de 

 piquans a I'opercule; leur tete est entierement depourvne d'dcailles, et la gueule est 

 armde de dents poiutues et ecartees. 



Under the heads of Sandat and Sandre, simple cross-references were 

 given, viz: 



Sandat. Pois. V. Sandre et Perche, sous-genre Centropome 

 (vol. 15 p. 97.) 



Sandre. Sandat. Pom. Sous-genre de Perche. V. ce mot. (B.) 

 (vol. 1."), p. 98.) 



In 1828, Stark I defined the genus as follows: 



* Nouveau Dictionnaire d'Histoire Naturelle, n. ed., vol, 30, pp. 126, 129. 

 t Dictiouaire des Sciences Naturelles, v. 47, p. 173,
