As Molin designated no type, we herewith designate as such the species 

 (Esophagostomum subulatum = Strongyhts dentatus Rudolphi, 1803, this selec- 

 tion being made for the following reasons: (1) As this form inhabits a 

 domesticated animal, it is much more easy to obtain than forms inhabiting 

 wild animals; (2) it is the only species Molin figured; (3) Molin evidently 

 intended this species as type, although he did not definitely designate it as 

 type; (4) this designation agrees with the principle of page precedence.
