plateau. The first of these extends from the sea to a point 30 to 100 

 miles inland, according to the configuration of the country, and its most 

 typical plant may be said to be the cocoanut palm, which will grow 

 wherever moisture enough is obtainable. The soil is over parts of 

 this belt strongly calcareous, being of recent geological formation, 

 abounding in various fossils such as anamonites and trilobites. Other 

 parts are the result of silt being carried down by erosion of the older 

 interior mountains. The rainfall in this part is very scanty, as the 

 storms come from the east and are intercepted by the highlands and 

 mountains, only the heaviest and most general rains for a small portion 

 of the year reaching the lowlands to the west. The vegetation is in 

 consequence sparse, consisting of a few shrubs and thorny or fleshy 

 trees. The grass grows in little discrete clumps and dries up and almost 

 disappears during the greater part of the year. In this region only 

 five species of Cicindelinae were encountered: Cicindela brevicollis 

 intermedia Klug, C. melancholica F., C. nitidula Dej., C. cdbinda Bat. 

 and Eurymorpha cyanipes mouffleti Fairm., the last three of which 

 occur on the seashore. 



The second region may be said to extend inland from the first region 

 to a point marked by the limits of the occurrence of the baobab tree 

 (Adansonia digitata). The basis of this is a vast primary system, 

 consisting of various metamorphic rocks, chiefly granite and sandstone. 

 The soil is a sandy loam alternating with red clays. Of course, there 

 is a great mixture of soils in the lower levels and valleys of this region. 

 Huge granite mountains and boulders abound. The vegetation is 

 very dense in canons and valleys and along rivers, -..and in the rainy 

 season the grass is often long, coaree and deixse, forming a sort of jungle. 

 Many large trees (Anonacese, Anacardacese, Guttiferse, etc.) abound 

 in the jungles near streams. The most inland valleys of this region 

 have a flora approaching that of the highland region yet to be described, 

 and it was here that most of the species discussed in this paper were 

 taken, our specimens including Cicindela Mechowi Qued., C. lutaria 

 W. Horn, C. saraliensis Guer., C. uncivittata Qued., C. infuscata Qued., 

 C. Putzeijsi W. Horn, C. angusticollis Boh., C. villosa Putz.. C. flavi- 

 pes Putz., C. Wellmani W. Horn, C. reticostata n. sp., Odontochila 

 erythropyga Putz., Cosmema Wellmaiii W. Horn, C. marginepunc- 

 tata W. Horn, C. auropunctata Qued., etc. The climate of this region 

 is intermediate between that of the foregoing and that of the region 

 about to be described, being cooler and moister than the lowlands, 

 without equalling in these respects the highlands. 



The third region is the high plateau forming the Bihe and parts of
