completely failed to recognize the relations of the two. (1) In 1828 

 (tome second, pp. 124-126) they described the large-mouthed species 

 as a new generic type (under the name Htiro nigricans), but, misled 

 by an injury to the spinous portion of the dorsal fin (and apparently 

 the loss of the seventh spine), they ranked it in their group of Per- 

 coids with two dorsal fins, attributing to it a first dorsal with six 

 spines, and a second with two spines in front (instead of ten dorsal 

 spines). (2) In the following year (1829) and volume (tome troisieme, 

 pp. 54-58), they described the small-mouthed species, identifying it 

 with the Lahrus salmoides of Lacepede, and forming for it (and at 

 the same time associating with it an Australian fish) the genus Grys- 

 tes : this was referred to the section of Percoids with a single dorsal 

 fin and placed after Centropristes and before Bhypticus. The de- 

 scriptions of both species (after making allowance for the error in- 

 duced by the state of the dorsal in Huro) were quite good, and es- 

 pecially in the case of Grystes salmoides, much better than any sub- 

 sequently published, and they can consequently be identified without 

 difliculty. 



Subsequently, Dr. DeKay, in his "Zoology of New York,"* re- 

 produced the figures and (in a modified form) the descriptions of 

 the two species from Cuvier and Valenciennes' work; but, failing to 

 identify them, redescribed and refigured one of them {Grystes sal- 

 moides) under two names (Cenirarchus fasciaiiis=Cichla fasciata 

 Les., and Cenirarchus obscurus DeKay, n. sp.). Of course all were 

 adopted by Dr. Storer in his '' Synopsis of the Fishes of North Amer- 

 ica."! I" those works, therefore, the species stand vmder three generic 

 and four specific names.
