LIST OF FISHES. 



MARSIPOBRANCHII * 



1. Ichthyomyzon concolor (Kirtland). Of this 

 species only larval forms were taken. One large larva, 

 seven inches in length, showed the following colors : 

 dull yellow, pigmented above with fine brown specks, 

 giving to the back a brownish cast ; this is interrupted 

 in the mid-dorsal line, leaving a yellow vertebral line; 

 fins yellowish, brightest at base. Young larva, two 

 and one half inches long, were light olive brown, with 

 fine brown specks above; dark around base of anal fin. 

 Eyes wQvy slightl}' developed. The 3'oung larvae were 

 taken from a mass of sand and mud seined from the 

 bottom of Sawmill Run. 



On October 3, 1898, in Big Jelloway Creek, Mr. J. 

 D. Parker took a large Black Bass upon which were 

 found two small lampreys, presumably of this species, 



*Our larval lampreys were identified by Dr. R. \V. Evermann, to whom we are also 

 indebted for many helpful suggestions.
