The Queensland Naturalist. 
April, 1934. 
‘ ‘ Flagellates in Certain Queensland Plants — Preliminary 
Notes” (Proc. R. Soc. Qld., Vol. XXXIX., p. 22, 1928), 
was apparently the first notice of their occurrence in the 
Australian flora. Bancroft’s discovery was of their pre- 
sence here in the milk of Sarcostemma and Hoya, two As- 
elepiads, and in that of Ficus scabra. He mentioned also 
that certain insects performed the role of intermediate 
host for these latex-occurring flagellates, and in the case 
of the Hoya a plant bug, Oncopeltus quadriguttatus . 
Ceratodus and Barramundi. 
Dr. Bancroft during his residence at Eidsvold bestowed 
particular attention on the Ceratodus Forsteri and its 
habits as displayed in the Burnett River. 
In May, 1916, he contributed to the Royal Society 
of Queensland some notes on a second ancient fish, the 
Dawson River Barramundi ( Scleropages Leichhardtii ) , 
(vide Proc. R. Soc. Qld. Vol. XXVIII., p. 93, 1917). On 
28th May, 1923, he made a further contribution to the 
Society on this Pish, entitled 4 ‘Some Further Observa- 
tions on the Dawson River Barramundi — Scleropages 
Leichhardtii” (Proc. R. Soc. Qld. Vol. XXXV., pp. 46-47, 
1924). In this he stated inter alia that the fish carried 
its spawn in its mouth, and that when meshed in the net 
ejected it, also that previously (1922) he had discovered 
that the “Salmon Cat-Fish” of- the Burnett River likewise 
carried ova in its mouth. 
Palm Island. 
Until a year or two before his death he had for a few 
years filled the post of Medical Superintendent at the 
Aboriginal Settlement, Palm Island, North East Queens- 
land, and a large series of botanical specimens were col- 
lected and forwarded to the Queensland Herbarium. 
General. 
A special feature in Dr. T. L. Bancroft’s attitude of 
mind towards science was the free, unreserved, and full 
manner in w T hich he co-operated with other naturalists. In 
this way he co-operated with C. W. de Vis and later Dir- 
ectors of the Queensland Museum, F. M. Bailey in his 
work on Queensland plants, J. H. Maiden in his work on 
Eucalypts, J. B. Cleland on the food of native birds, H. 
Tryon on fruit flies and other insects, E. AV. Ferguson 
on Tabanid flies, and others, both in Australia and abroad. 
His name is commemorated in botany and zoology by the
