68. Sarasin Brothers on the Geological History of Celebes. 
[Ueher die geologische Geschichte der Insel Celebes auf Grund der 
Thierverhreitung. Von Dr. Paul Sarasin und Dr. Fritz Sarasin. 1 vol. 
4to. Wiesbaden, 1901. 170 pp. ; 19 pis.] 
This learned and well-executed memoir is an attempt to 
explain the complexities of the existing fauna of Celebes by 
a careful study of its land-animals, to our knowledge of which 
the authors have largely contributed. The Land and Fresh- 
water Mollusks, the Reptiles and Amphibians, the Birds, 
the Mammals, and the Land-Planarians are all thoroughly 
discussed, and their distribution illustrated by a series of 
elaborate maps. Four " land-bridges '^ are shown to be 
necessary to account for the complications of the Celebeau 
fauna, and are supposed to have formerly connected this 
strange island with Java, the Philippines, the Moluccas, and 
Flores. No one interested in distribution should omit to 
study this valuable piece of work.
