time, and of appreciation for the patience of my kind 
listeners, unable to carry out an original intention to refer 
in detail to it; yet I may hurriedly allude, as convenient 
references for any future enthusiastic disciples, to— 
The ‘ Geographical Distribution of the Zoological Record.’ 
Giinther’s ‘ Catalogue of Fishes.’ 
Giinther’s ‘ Study of Fishes.’ 
Dr. Savage’s ‘Study of the Ichthyological Fauna of the 
Ogooué’ (in Gaboon), 1880. 
Dr. Rochebrune’s ‘Fish Fauna of the Senegambia,’ 1883. 
To our shame, zoological work and its record are making 
headway in other Possessions than our own. Look to the 
admirable works just quoted of Doctors Savage and 
Rochebrune. They have but recently come into my 
hands, so that time, even if space did so, will not admit. 
of my taking advantage of them. 
Of the zoological division of the earth’s surface as pro- 
posed by Mr. Sclater, the Ethiopian region stands forth as 
including Africa south of Sahara, Madagascar, and the 
Mascerene Islands, also southern Arabia. 
Then again as to the fauna of fresh-water fishes, Dr. 
Giinther has proposed the division into zones, among which 
stands the equatorial zone, noted by the development of 
Silurida, and characterised as far as the African region is 
concerned by the presence also of Dipnoz and Polypterida, 
Chromides and Characinide, being numerous, with Mor- 
myride present and Coditide absent. 
This authority has further divided the equatorial zone 
into four regions, one being described as African, with 
which we have now more to do than with any other, but 
which cannot according to him well be treated as to its 
fish fauna as absolutely distinct; for there “exists, for 
instance, a great affinity between the Indian and African
