K0.2194. NORTH AMERICAN PARASITIC COPEPODS— WILSON. 59 



In all the species examined by the present author the eye is just 



above the esophagus and a considerable distance beneath the dorsal 



surface, as is shown in figure G9. 



In dealing with this genus Fowler^ said in the key to the genera 



of the Lernaeidae (p. 8G) : 



" b. No vestiges of feet ou under surface of body, nor any appendages repre- 

 senting them Lcnicacnicus." 



and again (p. 87), in the genus diagnosis of Lernaeenicus, " Thoracic 

 limbs placed close together just behind head, first t\Yo biraniose, 

 third and fourth uniramose, and all with two joints." The latter 

 of course is the correct statement. The spelling " Lerneaenicus " is 

 too obviously a printer's error to be worthy of a second thought.
