Dejinition. — Zygospyrida with numerous (seven to twelve or more) basal feet, 

 without coryphal horns. 



The genus Gorgospyiis agrees with the three preceding genera in the possession of 

 numerous basal feet, but differs from them in the complete absence of any horns on the 

 coryphal face. It represents therefore the " hornless polypedal Zygospyrida,' and may
