Owing to the fact that they had all been preserved in 

 formalin, we had greater difficulty in making a thorough 

 examination of the worms. The anterior end and body 

 fragments show the same characters and measurements as 

 those from the ox. The vulva is similarly placed. The 

 ornamentation is alike, and the embryos are similar in 

 regard to the head and tail ends and the annulations. We 

 did not And any male specimens and consequently cannot 

 absolutely identify the filaria from the camel as being 

 specifically the same as that from the ox, though we have 

 little doubt as to their identity since they agree in all 

 points of comparison in regard to the female worms and in 

 the subcutaneous habitat of the nematodes. 



Comparison with other Camel filariae.— The finding of 

 this parasite in camels raises the question of its identity 

 with Filaria e vans i, Lewis. Apart from the differences 

 in location of the parasites in their hosts (Lewis 1 ) mentions 

 that the adults of F. evansi were found in tangled masses 

 plugging the pulmonary arteries, and were also present in 

 the mesentery, we cannot find, in the meagre descriptions 

 of the adults of F. evansi which are available to us, any 

 references to a cuticular ornamentation comparable to that 

 of our parasite or F. reticulata, features so striking as to 

 at once arrest attention. Portions of an adult male filaria, 

 presumably F. evansi, were taken from a bronchial tube of 

 one of the West Australian camels. On examination it 

 was seen that though it possessed fairly prominent annula- 

 tions, yet it lacked the distinctive structures above referred 

 to, and moreover the relations of the various parts at the 

 head end were unlike in the two parasites. It was at first 

 thought that this worm might be Strongylus filaria, Rud., 

 a nematode which has frequently been found in camels in 

 India, but this was not the case. We have also compared
