112 A TOUR AMONG THE ISLANDS 



As has been said, the island consists mainly of a steeply 

 rising grass-clad conical hill, a little over a mile long and 

 half as broad ; its north-east end slopes less steeply, 

 and here is evidence of former banana cultivation, the 

 shambas now overgrown with bush and creepers ; some 

 of the rose flowered " Ekirikiti " trees first noted on 

 Lukalu were seen. There were also thick bushes of the 

 usual kinds, and beds of the Salvia-\ike plant. Along the 

 south-east shore are bold cliffs, at the foot of which are 

 two little bays with beaches of pebble ; the south-west 

 shore is formed of unbroken rocky strata rising steeply 

 from deep water ; the west shore slopes less steeply and 

 is fringed by bushes, so that, on the whole, the island 

 seems unfavourable for Glossina, which yet was numerous. 

 Three crocodiles and one Enswa-swa were seen, but no 

 traces of hippo. Fruit eating bats were abundant, and 

 small rodents were very numerous in the tussocky grass, 

 so that Kiuwa was called a " rat island." 



In the old banana plantations sunbirds and weavers 

 were very plentiful ; flycatchers were scarce, and none 

 of the black and white species were seen. A thrush was 

 heard singing, which, though plentiful at Entebbe on the 

 mainland, I had never heard before on an island. 



Only one single specimen of Nephila spider was 

 seen ; no termite hills were seen anywhere on the 

 island. 1 



The butterflies of Kiuwa were rather interesting (see 

 table, p. 125) ; three species of small brown Acraea were ex- 

 tremely abundant, but encedon was not seen. Nymphalines 

 were very scarce ; a Pierine scarcely ever met with on the 

 islands was quite abundant on the beaches on the south- 

 east shore ; two Lycaenids not common everywhere 

 were noted as abundant ; Hesperidae were very scarce in 

 individuals, and only four species were seen. 



On February 20th we moved camp from Kerenge to the
