[Mr. Latham's dried specimen identified as My- 

 oxocephalus mitchilli differs from specimens of aene- 

 us strikingly in color, being darker, the dark and 

 white more contrasted, the fins more boldly marked. 

 The ventral fins especially have three or four very 

 bold black cross-bands, broader than the white inter- 

 spaces, whereas in aeneus they are but faintly marked. 

 The back seems to have been less elevated than in 

 aeneus and the spinous dorsal is more elevated, espe- 

 cially posteriorly, its longest spines equal V2 head. 

 Evidently this is the form described by De Kay as 

 mitchilli (Cuvier & Valenciennes), (New York 

 Fauna, Fishes 1842), and presumedly scorpio (Mit- 

 chill) on which mitchilli (C. & V.) was based. It 

 is the same as a specimen with 10 anal rays (No. 718 

 A. M. N. H.) which was probably supposed to be 

 the young of the Daddy Sculpin, groenlandicus, as it 

 is in the same jar with a specimen of that species from 

 Casco Bay, Maine, both labelled scorpiodes! This lat- 

 ter specimen of mitchilli is in good preservation. It 

 has the back little elevated and the spinous dorsal a 

 little higher than any aeneus examined, — its longest 

 spine not quite half head. The colors are like those 

 of Mr. Latham's specimen. An aeneus 4 1 /4 in., total 

 length from Long Island with unusually high spi- 

 nous dorsal has its longest spine 2.3 in head. No sat- 

 isfactory structural difference, however, has been 

 found between these two specimens of mitchilli, and 

 aeneus. It is possible that recent authors are correct 

 in synonimizing the forms but they look different. —
