\ 1 Deducting from M. Sauvage’s list three species which I
consider merely synonyms, and allowing for four others which
I believe to figure in my and M. Sauvage’s lists under different
names, I compute the total number of species known at present
from this river to be fifty-one, a number which may be expected
to be doubled by future investigations. The fish-fauna of
the Nile consists of about ninety species.
The localities which will be mentioned in this report are the
following: ;
Warri, on the Forcados River (mouth of the Niger).
Azumine Creek, freshwater, running into the Opobo
River, with a Swift current, 25 miles from the sea
(Niger delta region).
Egwanga, on the Opobo River (Niger delta region).1
Corisco Island, off the Gaboon Coast.
Lambarene/ Ogowi River.
Talagouga, about 180 miles from the mouth of the
Ogowe.
Kondo-Kondo, an island in the Alemba Rapids of the
Ogowe.

The Reptiles were collected at Lambarene, and belong to
the following species :—
1. Cycloderma Aubryi, D. B.— A young specimen well
agreeing with one figured by Peters (MB. Berl.
Akad. 1876, p. 117). ’
1 = Lembarene Island, sometimes also spelt Lambarenie Island.
