342 PROCEEDINGS OF SECTION D. 



the general anatomy of the nematode, while confirming much that 

 those authors and ourselves have stated, Drs. MacFadden and 

 Leiper in several points agree more closely with ourselves in details 

 in which we have differed from those authors. They have missed 

 the presence of the first pair of caudal papillae, which are undoubt- 

 edly present in the male, and so have incorrectly described 

 the worm as having only six pairs of genital papillae instead of 

 seven pairs. 



The detailed structure of the worm has not been described 

 at all, nor is there any reference to the excretory system, so that 

 we are unable to make any comparisons on these most difficult 

 parts of the subject. 



NOTE ADDED OCTOBER, 1911. 



While this paper was passing through the press we have had 

 an opportunity of consulting " Enterprise in Tropical Australia " 

 (1846), in which the author, Mr. G. W. Earl, writes of the importa- 

 tion into the settlements at Melville Island and Raffles Bay of 

 " stock from the Dutch town of Coepang, at the south-west extreme 

 of the Island of Timor " (p. 44), apparently circiter 1824. He also 

 definitely records (p. 65) that in the year 1840, amongst a number 

 of vessels which brought supplies, including cattle from neighbouring 

 European settlements in the Indian Archipelago, " the ' Lulworth,' 

 an English schooner on a trading voyage among the Indian Islands, 

 . brought cattle, horses, and maize from Coepang " to 

 the British settlement at Port Essington, other vessels also following 

 later from Coepang. 



Further, we have recently seen a copy of a dispatch by Captain 

 Everard Home, dated from H.M.S. " North Star," 19th April, 1843, 

 which constitutes a report on the Port Essington settlement of that 

 period. In this he mentioned besides buffalo, English cattle, etc., 

 the presence of Indian cattle. We are informed, too, that the 

 descendants of these Indian cattle are now running wild on Coburg 

 Peninsula. In addition to this we have been advised by Mr. H. W. 

 H. Stevens, of Brisbane, and others, that the British- Australian 

 Telegraph Company imported into Port Darwin, about 1872, 

 several cattle from Batavia, that subsequently some of these cattle 

 were turned out and that they made their way back to the Adelaide 

 River, where even to-day their crossbred descendants may be seen, 

 indeed have recently been seen by one of us. Some of these cross- 

 breds were examined and found to be badly infected with Oncho- 

 cerca nodules, while several buffaloes were examined and found to be 

 unaffected. There has thus been the possibility of the direct intro- 

 duction of these parasites into Australia along with native Eastern 

 cattle. 



It is interesting in this connection to record that Mr. S. L. 

 Symonds, Government Veterinary Surgeon in the Federated Malay 

 States, informs us that he has " only once noted worm nodules in
