and the species taken by Le Sueur in 1816, and described by 

 him in the first vokime of the " Journal of the Academy of 

 Natural Sciences,"' under the name of Gadiis maculosiis in 

 1817, and in the " Memoires du Museum d'Histoire Naturelle, 

 t. y. p. 159," for 1819, and also there figured, under the name 

 of Molva maculosa. It is very evident that that figure was 

 drawn from a preserved specimen, which had lost its original 

 proportions by the process of drying. The difference which 

 exists between the Lota maculosa and the species I have 

 now described, may at once be recognised, by examining the 

 plates of each species contained in this number of our Journal. 

 In the first number of the '' American Monthly Magazine and 

 Critical Review," for 1818, Dr. Mitchill refers to a species 

 which he calls Gadiis lacustris. In the course of his re- 

 marks, he states that this "appears to him to be the same 

 fish" that •' Le Sueur found in Lake Erie, and has figured," 

 &c. He supposes a fish which is found in Sebago Pond, 

 Maine, and called there the Sea-cusk, to be the identical 

 species. Never having seen a Lota from the last locality, I 

 am unable to decide what the fish referred to may be. Dr. 

 MitchilPs Gadus lacustris is evidently the Gadus maculosus 

 of Le Sueur, and he infers, without having ever seen the 

 species, that the Lota from Maine, is the same fish. 



Etheostoma Olmstedi. 

 Plate Y. Fig. 2. 



The beautiful little species here described, was found at 

 Hartford, by Charles H. Olmsted, Esq. President of the Hart- 

 ford Natural History Society. He is a very accurate observer, 

 and is striving to advance the science which has been so long 

 and so inexcusably neglected among us. I take great pleas- 

 ure in associating his name with this species. 



Length of the fish, which is of a cylindrical form, three 

 inches. Color yellowish, marked upon the back and sides witli 

 reddish brown blotches, which, when looked upon from either 

 extremity of the fish, resemble interrupted longitudinal band-,
