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

 by Chatin encysted in the subcutaneous tissue, and immature 

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

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

 show^ed four transverse rows 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 w^e have described.
