The Queensland Naturalist. 
December, 1926 
There is a pair at least of the fine red-backed hawk 
(Haliastur leucosternus, Gld.) also known as the white- 
headed Sea Eagle, now flying about the river at Bulimba. 
These or others have been with us ever since we came to 
Bulimba over 41 years back. They sometimes perch on 
the old fender piles of the wharf now fast falling to decay. 
I often watch them, for they are always a pleasing sight. 
We sometimes hear the call of the fish-tail flycatcher 
•or Drongo (Chibia bract eata) though they will soon be 
departing now on their northward quest. They usually 
arrive here at the advent of summer, in fine feather, but 
depart in poor condition. The rufous fan-tail (Rhipidura 
rufifrons) is now in evidence in our garden, but the 
white-shafted (Rhipidura albiscapa) has not yet left its 
summer home in the mountains. Last December both 
these birds were abundant on Roberts Plateau, and T have 
also noted R. albiscapa at Toowoomba on the Range dur- 
ing the same month.

A REMARKABLE ABERRATION IN A COMMON 
BUTTERFLY. 
(By L. Franzen.) 
Of the two butterflies shown on Plate 1, the one to the 
left is a typical example of our common skipper Trape- 
zites eliena Hew. On the right is a remarkable aberration 
of the same species. k The difference in this specimen from 
typical form are as follows : — 
Above: — Forewings bronze brown, discal area finely 
dusted orange, cell spot irregular and reduced in size, 
total subapical spots, elongate discal spots in area, two 
and three, a minute and obscure dot in area two, and 
spot in area one, small and practically emerged in the 
pale orange streak, parallel to dorsum. 
Above. — Hind wings bronze brown, faintly dusted 
orange, otherwise typical. 
Beneath. — -Fore-wings in colour as in typical form, 
but paler, subapical spots present, but very obscure, 
discal spot in area, three very small and almost round. 
This aberrant butterfly is the property of Mr. A. J. 
Beck, from whom I have obtained a specimen on loan 
for the purpose of publishing these notes. The capture 
of this very rare form was effected by Mr. Beck at 
Virginia, near Brisbane, in September, 1924.
