 translation of Diesing's description, bat add Spiroptera

 synonyms. The various authors Btate that the parasite is 

 peculiar to equines. 



Prom the above it appeared t

 available to us, had accepted Diesing's statements regard- 

 ing the structure of the male worm. Accordingly we had 

 no option but to separate our worm from F. reticulata. 

 Since the publication of our preliminary note, in which we, 

 like Barnard and Park, drew attention to the marked 

 similarity of the adult worms (especially the females), we 

 have had access to Pader's 4 paper on "Filariose du Liga- 

 ment suspenseur du boulet chez le cheval," published in a 

 journal which was not previously available in Australia. 

 He dealt with the anatomy and histology of F. reticulata, 

 and gave an account of the earlier references to the finding 

 of this nematode. In his description he shows that the 

 males of F. reticulata, like other Filaridae, possess two 

 unequal spicules instead of one as described by Diesing, 

 but these are considerably longer than those of F. gibsotti. 

 Besides this the arrangement and size of the papillae as 

 given by Pader are quite different from those of the male

 the genus Filar/'; M idler, points out that the type species
