Immature forms, 3 mm. long, without sexual organs, weie found 

 by Oliatin encysted in the subcutaneous tissue, and immature 

 females, not less than 4 mm. long, encysted in the subscapular 

 air-sac, of a pelican {Pelecamis onocrotalus). The rounded head 

 showed four transverse lows of hooks. There were six tubes of 

 unequal length, in the position of the cervical sacs. No mention 

 is made of any spines on the body. These features necessitate 

 the provisional inclusion of the species in the Gnathostomidae, 

 but, if the details are correct, exclude it from any of the genera 

 that we have described.
