(3) Microflland of Voduryus sfriffoides.^In our second 

 paper we have referred to the Microfilaria of this species of 

 frogmouth. In a further specimen, also forwarded to us from 

 Eidsvold, Queensland, by Dr. Bancroft, these parasites were 

 very numerous, and Leucocytozoa were also present. The 

 Microfilariae showed fine transverse striations, and the tail 

 tapered to a sharp point, whilst the anterior end was blunt. 

 In our previous paper we gave the total length as 90 to 100 \iy 

 but an examination of this bird shows they may reach nearly 

 140 /A. The following are the measurements, in micromilli- 

 metres, of several individuals: — Total lengths, 98, 100"3,. 

 105-4, 131-5, 137-4, 138: anterior "clear" area, 3-4 to 5-5; 

 anterior end to first "spot," 29-5, 27-5, 29*5, 31, 38, 39*5; 

 length of first "spot," 2 to 3"4 ; from first "spot" to second 

 "spot," 26, 24, 26, 24, 38, 29*5 : length of second "spot," 

 2 to 5 JUL, in one instance, perhaps due to injury, 7 fi ; from 

 second "spot" to posterior end, 38, 43-5, 43, 52 (with a doubt- 

 ful third "spot" in the exact middle of this area), 51, 44 (with 

 a third "spot" 27 /a from the anterior end of this area). The 

 greatest diameter was 3 '5 to 4 jn. Microscopically, though 

 the measurements vary in individuals and seem to group them- 

 selves about two means, there is nothing to suggest that more 

 than one species is present. 



(4) Microfilaria of Ei(rysfomus pacificus. — Another speci- 

 men of the roller infested with Microfilariae was forwarded by 

 Dr. Bancroft from Queensland in January, 1912. 



(5) Microfilaria of Collyriocichla harmonica. — Micro- 

 filariae were detected in the blood of a specimen of the har- 

 monious thrush obtained at the Hawkesbury River, New South 

 Wales, in June, 1912. Their features may be summarized as 

 follows : — Anterior end, blunt : breadth throughout more or 

 less uniform, though the posterior third dirainishes slightly ; 

 posterior end also blunt ; fine cross-striations : a very short 

 "clear" area at the anterior end. Total length, 96 to 103 jut; 

 anterior "clear" area, sometimes 2-5 jui long: first "spot," 

 20-5 fjt, from anterior end in three specimens, and 26 /x in a 

 fourth : a V-shaped "break" at about 36 to 38 ju, from the 

 anterior end ; a third "spot" at 57 to 62 jul from the anterior 

 end : greatest breadth, 3-5 /x. 



(6) M icrofilaria of Myzomela sangnineolenta. — Another 

 specimen of the sanguineous honey-eater infested with the 

 exceedingly long Microfilaria mentioned in our second paper, 

 and also harbouring Hcdfericlia, Leucocytozoa, and trypano- 

 somes, was kindly forwarded in October, 1911, from Eidsvold 

 by Dr. Bancroft.
