als prefer to sit on branches also of very high trees , that are hanging 

 over the water or stand at least immediately on the river. When shot 

 they fall or jump into the water to have a Chance of escape , as they 

 swim and dive exceedingly well ; when hunted on the ground they always 

 run to the water and swim with considerable speed to the opposite side. 

 This variety or race seems to be restricted to Central-and Sou- 

 thern-Celebes. Bleekee's and my specimens are from the southern 

 part; A. B. Meyeb obtained his specimen in the central part and 

 communicated to Peters, that it is not found in North-Celebes. During 

 a short residence at Luwu in the central part of Celebes the inhabi- 

 tants told me of the existence of a large lizard living near rivers, 

 that, according to their description, must be a Loplrara.

Sumatra: Kaju tanam, Solok and Singkarah, 3 sp. 



Java: Buitenzorg, 4 sp.

Celebes: Makassar, 1 sp. 



Tello near Makassar, 1 sp. 

 Saleyer, 2 sp. 

 This species is easily to be distinguished from Varanus salvator by 

 its larger scales of the upper surfaces and by the totally different 

 colour. It was detected by A. B. Meyeb on the Togean-Islands near 

 the central part of Celebes and described by Peters. I am inclined 

 to believe, that it is a typical species of the celebesian fauna; for I 

 found it in South- Celebes and on the Island of Saleyer, that belongs 

 faunistically and geographically to Celebes. The Island of Saleyer lies very 

 near to the south-western peninsula of Celebes and is connected with 

 it by several small islands. On the island of Flores I observed only 

 the common Varanus salvator. 



Lacertidae. 

 Tachydromus.
