OBSERVATIONS. 



This species is very abundant in the Delaware and 

 Schuylkill Kivers. The basal portion of the labrum in 

 Lister's figure of plate 113 above quoted is deficient, nev 

 ertheless I have no doubt that the figure v\'as intended for 

 this spcciesj and that his figure 4. of pL II is intended to 

 represent the variety.
