This is the third Opalinid found in Bufo haematiticus. We have 

 already described Zelleriella hufoxena and Gepedea dolichosoma. 

 This third species is quite flat. The material is none too good, nor 

 is it abundant. It does not seem best to name it from this material. 

 Cepedea dolichosoma was present in this individual host along with 

 this unnamed Opalina. 



OPALINA CAROLINENSIS, new species. 



Type. — United States National Museum No. 16557. See also No.

 Prairie, Florida, April 22, 1901, E. A. Mearns collector; the other
