and its line was marked by heavy purple nimbi 

 wdth hangings and curtains of grey rain. We 

 anchored off Sumanga, an open roadstead, about 

 four miles south of the embouchure : here the 

 land is low, and the village, on account of the 

 high tides, is built a good mile from the water. 

 It contains some large huts, and the people sup- 

 plied us with milk, rice, sugar, and custard apples. 

 Cattle, though plentiful, is subject, they say, to 

 murrain, and must often change air. Here pro- 

 bably the Tsetse fly is common, as at Kilwa, where 

 I found a fine specimen, afterwards deposited in 

 the British Museum. At that time its habitat

 the Zambeze river : in after years I met with 

 it upon the coast of Guinea, and MM. Antinori 

 and Piaggia observed it amongst the Jurs of the 

 Upper Nile, whilst Sir Samuel Baker saw it in 

 the country of the ' Latookas,' 110 miles east of 

 Gondokoro (N. lat. 4° 55'). It will probably be 

 found scattered in patches, especially of lowland 

 virgin-forest, throughout Intertropical Africa.

 tance, would place Bhapta, ' the last mart of 

 Azania,' at the 'embouchure de TOufidji ;' while 

 the older geographers prefer Kilwa. Ptolemy, I 

 have said, mentions three places of that name, to
