(1) Microfilaria sp. from the Little Cormorant, Phalacro- 



corax melanoleucus, Vieill. (Hawkesbury River, N.S.W. 

 Nov. 1910). 



These embryos were rather long, stout forms reaching 

 from 116 to 140 /* in length by about 6 /* in width. The 

 anterior end was bluntly rounded and of about the same 

 diameter as the main portion of the worm. The posterior 

 region tapered somewhat to end in a broadly rounded 

 extremity. Faint transverse striations were recognised. 

 The various breaks were situated as indicated. (Figs. 60, 

 61). 



(2) Microfilaria sp. from the Sparrow Hawk, Accipiter 



cirrhocephalus, Vieill. (Dr. Bancroft, Eidsvold, Q., 

 June 1911). 



These parasites were relatively long (100 to 130 /*) and 

 thin, possessing a uniform breadth of 3*3 ih excepting at 

 the posterior end which tapered somewhat to terminate in 

 a bluntly rounded tail. The "spots" were situated at 

 about 36, 74 and 94 per cent, of the body length distant 

 from the head end. (Figs. 65, 66.) 



(3) Microfilaria sp. from the Little Lorikeet, Glossopsit- 



tacus pusillus, Shaw. (Dr. Bancroft, Eidsvold, Q., June 

 1911 ; L. Harrison, Gladstone, Q., Oct. 1910). 



In a blood film made from this host by Dr. Bancroft, there 

 were abundant embryos, but they did not take up the stain 

 satisfactorily. They were fairly short (66 to 75/* long),
