on that, as appears from tlie number of scales, the absence of any on the 

 preopercular limb ("le limbe de son preopercule [etc.] en manquent"), 

 and the form of the dorsal. Even if it is certain that the flgiixe was 

 taken from a large-mouthed specimen, this would not affect the question, 

 inasmuch as we must accept the description when that is definitive, and 

 such is the case here. 



"(3) It may be held that the name is further specialized by Cuvier 

 and Valenciennes by its use to supersede the name of Le Sueur (p. 55), 

 and as a substitute for M. Dolomieu (vol. v, p. 5). 



"(4) The majority of the C. & V.'s specimens belonged to the small- 

 mouthed Bass. 



"(5) The figure was based on a large-mouth simj)ly through accidence 

 of size and condition, not selected on account of exhibition of characters. 

 In the same way, we might maintain that the type of Fomotis vulgaris 

 C. & V. (although the descrii)tion plainly points to Ewpomotis aureus) 

 was Lepomis palUdus [rather auritu^], for the figure apparently repre- 

 sents such." 



3. Micropterus variabilis Vaillant & Bocourt. 



Cicltla variahilis Le Sueur, MSS. 



Micropterus variaWis Vaillant & Bocourt, MSS., Mission Scientifique au Mex- 

 ique. 



This is the ordinary northern small-mouthed Black Bass, Micropterus 

 achigan, or var. achigan of authors, Micropterus salmoides achigan of the 

 present writer. 



4. Bryttus unicolor Cuvier & Valenciennes. 



Hist. Nat. des Poiss. vii, 464. 



A specimen collected by Le Sueur at Philadelphia, and doubtless the 

 original type, seems to be the young of Lepomis auritus. Some of the 

 specimens labelled Fomotis vulgaris are likewise Lepomis auritus. From 

 one of these the figure of the species was apparently taken. 



5. Bryttus punctatus Cuvier &. Valenciennes. 



Hist. Nat. des Poiss. vii, 462. 



The types of this species (Charleston, Holbrook Coll.) belong to the 

 species recently described by Prof. Cope as Lepomis apiatus (Proc. Am. 

 Philos. Soc, 1877) and by me as Lepiopomus apiatus (Bull. U. S. Nat. Mus. 

 X, 1877, 25). This species should therefore stand as Lepomis punctatus. 



6. Bryttus reticulatus Cuvier «fc Valenciennes. 



Hist. Nat. des Poiss. vii, 463. 



This species is unquestionably identical with the preceding, 



7. Pomotis holbrooki Cuvier & Valenciennes. 



Hist. Nat. des Poiss. vii, 466. 

 This species is the Fomotis speciosus of Holbrook, Fomotis microlophus 

 Giinther. It should therefore stand as Eupomotis holbrooJci. Xystroplites 

 longimanus Cope, is at least very similar, as also Fomotis pallidus Ag.
