 and of the genital atrium. The outer muscle zone of the penis papilla 

 (mp) consists of a very thick layer of circular fibers followed by a 

 normal layer of longitudinal muscles. The adenodactyl, instead of having 

 its opening at the gonopore, connects with a separate compartment (aa) of 

 the atrium lying posterior to the genital aperture. In streams and springs, 

 North Carolina, southern Virginia, and Louisiana. Literature: Kenk (1969).
