time there is a distinct southerly intrusion of the equatorial waters of the Indian 
Ocean, at some distance off shore, down towards, though not absolutely reaching, 
the Abrolhos Islands. 
Further substantial evidence supporting the correctness of the interpretation 
here submitted, is afforded by the results of synchronous readings of the sea tempera- 
ture obtained by the writer with the assistance of Mr. G. Beddoes, Mr. Broadhurst’s 
managing partner, in the vicinity respectively of the Abrolhos Reefs and at Champion 
Bay. These taken in the early morning of July, midwinter, 1894, at three feet 
below the surface of the water exhibited a difference of from ten to fourteen degrees 
Fahrenheit ; readings at the Abrolhos averaging 69° and 70°, while those at the 
Geraldton Pier registered as low as 56°. 
Many of the zoological data recorded in this Chapter were, it may be 
mentioned, embodied in a paper contributed to the 1895 Norwich Meeting of the 
British Association, and are published in abstract in the Proceedings for 
that year. Figures and descriptions of a lizard species, Egernia Stokesii, which is 
particularly abundant on Gun Island, in the Abrolhos group, will be found in 
Chapter ITI.
