All three forms of malaria are known from Queensland, 
viz., tertian or benign tertian (Plasmodium vivax, Gr. and 
Fel.), quartan (P. malarie, Lav.), and intermittent or 
malignant tertian fever (P. falciparum, Lemaire). The 
last has been introduced, chiefly by miners, from New 
Guinea, where it is endemic (Brein]l; Elkington; Booth- 
Clarkson ; Moore, 1914*). 
For references see Johnston, 1909c; Cleland, 1914c ; 
Turner, 1890; Breinl, 1912, 1913e, 1915; O’Brien, 
1908; Butler, 1912; Elkington, 1910, 1912, 1912c; 
Breinl] and Priestley, 1916a. 
All three types occur in districts of North Queensland, 
some of them being now endemic (e.g., P. vivax—in Cairns 
[Moore, 1914], and Port Douglas.f). 
O’Brien (1908), states that the type is almost always 
tertian, and only occasionally is quartan or malignant 
malaria met with in Northern Queensland. 
No trematode parasites have been recorded as far 
as I know, though a number of cases of Schistosomiasis 
occurred in Queensland, amongst men who had become 
infected by Schistosomum hematobium, Bilh., during the 
South African (Boer) War. 
Two Cestodes have been reported. 
Tenia saginata, G., Jnstn., 19106; 1910f (Brisbane), 
Nicoll, 1914d (N.Q.)—apparently uncommon in 
this State. 
Echinococcus granulosus, B. (the hydatid stage, more 
commonly known as Echinococcus hominis or 
HE. veterinorum, R.). For’ references see 
Johnston, 1909c; rare in N.Q. (Nicoll, 1914d) ; 
*R, F. Jones gave an account of the ** Diseases of British New Guinea ’’ 
(Ir. Soc. Trop. Med. Hyg., January, 1911 ; Abstr. in A. Med. Gaz., June, 
1911, p. 356). Amongst those met with were malaria, both simple tertian 
and estivo-autumnal; amcebic dysentery and liver abscess; Filaria 
bancrofti ; ulcerating granuloma; and dengue (imported); while Anky- 
lostomiasis was encountered only in that part which was then known as 
German New Guinea.

presence of Malaria in Cairns and Port Douglas (Q.) and Overland Corner-
