Tvere all found to belong to H. microstoma as previously 

 recorded by me. 



H. muscce mnst be added to the list of known entozoa 

 •occurring in N.S.W. and Queensland.* 



Dr. J. B. Clelandf recorded the presence of Spiroptera 

 microsioma in nodules or cavities in dense fibrous tissue in 

 the stomach of horses in West Australia. Both of his 

 records evidently refer to H. megastomaX. Neither H. 

 muscce nor H. microstoma has. as far as I know, been noted 

 as occurring in that State. 



Gongylonema ingluvicola Ransom. 

 Last year. Dr. Cleland forwarded some small worm 

 tumours from the walls of the crop and gizzard of a chicken 

 (Sydney District). The causal parasites have been indenti- 

 fied as G. ingluvicola, ^vhick, as far as I know, has been 

 recorded only fn^m a locality in the United States (Ransom? 

 1904). 



ACANTHOCEPHALA. 



Centrorhynchus asturinus Johnston. 

 This parasite, which infests the white hawk, Astur 

 novaehollandiae Gm., in North Queensland, was described 

 as a GigantorhyncMis but is now transferred to the genus 

 Centrorhynchus, the chief characters of which have been 

 summarised by Van Cleave fl916). The male has only 

 three long tubular cement glands instead of several smaller 

 ones as shoAvn in mj- original figure (1913, pi. 17, fig. 41). 



I have identified as belonging to the species a few 

 specimens collected by Dr. J. B. Cleland from a crested 

 hawk, Baza suhcristata Gd., in December, 1916 at Mummul- 

 gum, near Casino, N.S.W. , as well as a number in the coUec- 



*My attention has recently been drawn to a reference in the Scientific 

 AustraHan (June 1918), where it stated that a paper by Mr. G. F. Hill, 

 dealing with the life histories of Habrone r.a muscce, -5f. micrGstoma and^. 

 ruegastoma, had been read before the May meeting (1918), of the iloyal 

 Society of Victoria.

 AustraUa, 1909, p. 3 ; Trypanosomiasis, etc. Bull. 34, 1909, p. 13. 



JDesmond ( Journ. Agric. Ind. South Australia, 7, 1904, p. 539) referred 

 to the presence of Sclerosiomum hypostomum in tumours in the stomach. 

 of South Australian horses. The reference shouM be //. infgastoma.
