Fish are nowhere found in the rivers of Ivilima-njaro,

save in the Fiver Lumi, which flows into Lake Jipe. 
I give a drawing of the only kind caught in the Lumi,

which is the river of Taveita. It is probably a species 
of Barbel or Labio , of the family Cyprinidce . In Lake 
Jipe a silurus is very common, and there are many 
other kinds of fish also present, but the shores of the 
lake are deserted, nobody fishes there, and the fish 
would not rise to ordinary bait; and therefore as my 
time at Jipe was short, and my health bad, I had no 
opportunity of investigating its piscine forms. Fresh¬ 
water crabs of the genus Thelphusa {T. depressa , var. 
Johnstoni ) are present inmost of the mountain streams. 
They appear to be most closely related to the river- 
crabs of Natal and South Africa. 
Throughout this region butterflies are few and 
scarce. They do not penetrate much higher than 
8000 or 9000 feet. The common clouded vellow is 
often seen on Kilima-njaro. 
Bees and wasps penetrate to a height of 14,000 
feet. They belong principally to the genus Xyloropus. 
Most of the beetles are allied to, or identical with, 
South-east African forms. One new species has no 
allies nearer than India. Others are related to 
Abyssinian species, and some to the beetles of Somali¬ 
land.
