I have taken from the intestine of this bird some small 

 cylindrical distomid trematodes (Echinostomum sp.) whose 

 anterior end is provided with a circlet of hooks. (Near 

 Sydney, N. S. Wales.)

The white headed stilt. 



Trematoda :— Monostomum sp. 



Dr. Oieland collected a number of flukes belonging to the 

 Monostomidse and apparently to this genus. They were 

 found in the oesophagus and in the body cavity of the bird. 

 I cannot state which was the correct habitat, as there was 

 a perforation of the wall of the alimentary canal. (Murray 

 River, South Australia). 



Cestoda:— i. Taenia coronata, Krefft, I c, p. 220. (N.S.W.) 

 ii. Taenia rugosa, Krefft, I.e., p. 223. (N.S.W.) 



Both of these species are insufficiently described, and 

 have not as a consequence, been assigned to their true 

 genera. Fuhrmann 1 lists them under the imperfectly 

 known forms. 



In regard to T. nujosi, Krefft, the specific name rwjosa 

 was already preoccupied in the genus Taenia being used by 

 Diesing 2 for a tapeworm from the small intestine of a 

 Brazilian monkey, Cebits (Briodes) hypoxanthus. Conse- 

 quently Krefft's species requires re-naming. I would 

 suggest that this worm be dedicated to my friend, Mr. 

 Charles Hedley, Assistant Curator of the Australian 

 Museum, Sydney. As I hope to point out in a later com- 

 munication, this parasite in not a Taenia, but belongs to 

 the family Acoleidae, and probably to the genus Acoleus. 

 Accordingly the helminth may be listed temporarily as 

 Acoleus hedleyi, nom. nov. Dr. Cleland has recently
