190 INTRODUCTION TO CONCHOLOGY. 



blocks of wood or stone. This type reaches nearly to the 

 south-eastern corner of Asia^ where it is suddenly met at 

 Burmah, and in the Malacca peninsula, by the richly- 

 coloured Malayan type, which is so abundantly and beau- 

 tifully represented in the islands of the Eastern Archipelago ; 

 and truly its distribution among these islands is remarkably 

 local. 



Bulimi of Northern Africa have much in common with 

 their European brethren ; while such as dwell south of the 

 equator belong to a totally different type. 



Thus far is the conchologist indebted, for deeply inter- 

 esting and valuable information, to the researches of Mr. 

 Eeeve, whose summary of collected facts will doubtless 

 prove suggestive of future observations, and induce such 

 travellers as take pleasure in natural history to acquaint 

 themselves with the geological and physical history of the 

 earth-'s surface, and, while noting the precise localities and 

 circumstances of habitation connected with various genera, 

 to aid in determining the laws relating to geographical 

 molluscous distribution.
