In Indian lake, Lake Janet, and others in that vicinity, I noticed a remarkable variety of 

 the P. vulgaris, about four inches long. The appendix was black, margined with light blue ; 

 sides beautifully punctate with blood red ; abdomen bright yellow ; opercles longitudinally 

 striate with blue.

This beautiful little fish has derived one of its popular names, viz. Sun-fish, from the 

 glittering colors it displays while basking in the sun. The numerous spots on its body has 

 occasioned it to be called by the whimsical name of Pumpkin-seed, in some districts of the 

 State. In Massachusetts, it is often called Bream. It is of no value as an article of food, 

 but is often caught for amusement. 



The Common Pond-fish has a wide geographic range, extending from Lake Huron through- 

 out the eastern States. Accoiding to Dr. Kirtland, it occurs in the western waters. Along 

 the Atlantic, it is found as far south as Carolina, and probably still farther south.
