76 NOTES ON SOME ENTOZOA. 



Gurney, of the Entoniologist's Branch. Sydney, as 

 Mastochilus, sp. It is under this host name that these 

 tiny nematodes should be placed. 



My specimens were collected in various parts of Nevr 

 South Wales. 



Echinonema cinctum, Linstow. 



This roundworm was originally described as 

 Hoplocephahis cinctus, by Linstow (1898, p. 469), from 

 material taken in Queensland by Prof. Semon from a 

 bandicoot, Permaeles obesula. It is now recorded, from the 

 *' native cat," Dasyurus viverrinus, my specimen of the 

 parasite — a female — being collected from a dasyure secured 

 by Mr. T. Steel, in a suburb of Sydney. 



Filaria websteri, Oobbold. 

 This large nematode infests the bursa at the knee- 

 joint of several kangaroos and wallabies. I have recently 

 received specimens collected near Eidsvold by Dr. Bancroft 

 from Macwpus giganteus, M. dorsalis, and M. parryi. 



Habronema muscce (Carter). 



The larval stage of this parasite, Habronema muscce, has 

 been met with in two species of flies, Stomoxys calcitrant 

 and Musca domestica in Sydney, and in the latter in Bris- 

 bane. As far as I know, the larval form has not been 

 previously recorded from Australia. 



Ransom (1911, p. 690), has recently shown that H, 

 musccB is the larval stage of a parasite which infests the 

 stomach of the horse. 



A larval worm which has the general form and 

 characters of the above species occurs in the head region 

 of the common " cattle fly," found frequenting, especially 

 the e^^es of cattle, in Queensland and determined as Musca 

 vetustissima. I am indebted to Dr. Bancroft for specimens 

 taken near Eidsvold in the Burnett River district of this 

 State. 



Filaria clelandi, n. sp. 



(PI. II ; Figs. 7, 8). 



A single specimen — a male — was found by Dr. Bancroft 



in the peritoneum of a magpie, Gymnorhina tibiceii, shot 



near Eidsvold. Its length is 27 mm., and its breadth 



•62 mm. The cuticle is quite smooth. The ends are
