Physaloptera clausa is here, designated type on the following grounds: (1) Of 

 the original species, this alone is figured; (2) it occurs in an European ani- 

 mal which is not especially difficult to obtain, in fact, of the original hosts 

 of Physaloptera, this host (Erinaceus europims} is probably the most easily 

 obtainable; (3) Rudolphi's description of this species is more complete than 

 his description of any other member of the genus; (4) this ruling agrees 

 with page precedence.
