PISCES. 
Onty one species of Fish, the widely distributed Tilapia nilotica, L., was known 
from Rnwenzori, where specimens were found, between 5000 and 6000 feet, by 
Mr. G. F. Scott Elliot. ‘The same fish was obtained to the S.E., at 3200 feet altitude, 
by Mr. R. B. Woosnam, the leader of the present Expedition, Examples of two species 
were obtained near Fort Portal, alt. 4500 feet, viz Clarias carsonii Blgr. and Barbus 
portali Blgr., the latter being a new species which I have described and figured in the 
‘Fishes of the Nile.” From Irumu, in the Congo Forest, alt. 3000 feet, we have 
examples of five species: Alestes macrophthalmus Gthr., A. grandisquamis Blgr., 
A. imberi Peters, Barbus holotenia Blgr., and Barilius ubangensis Pellegr. A small 
collection made in the Aruwimi River contains representatives of ten species : 
Pellonula obtusirostris Blgr., Bryconethiops microstoma Gthr., Petersius woosnami Blgr., 
Micralestes acutidens Peters, Labeo parvus Blgr., Barilius ubangensis Pellegr., 
Chelethiops elongatus Blgr., Eutropius grenfelli Blgr., Synodontis greshoffi Schilth., 
and Mastacembelus congicus Bigr. 
Pellonula obtusirostris and Petersius woosnami have been described and figured in 
the first volume of the British Museum Catalogue of African Fresh-water Fishes.
