Some observations may perhaps be made here on the eggs of this re- 
markable animal, and with the more right, because I find nothing 
in literature ') about the manner in which tlie female deposits its eggs. 
I found numerous eggs on the smooth trunk and branches of an 
Urostigma rumphii. They have a glossy grayish- white colour , are semi- 
globular and are attached to the bark of the tree with a flat basis. 
Their greatest diameter is 14 mm., their smallest 11 mm. Always 
two eggs are found together ; they touch each other with flat surfaces. 
Now and then a different number of eggs are loosely united in a httle 
group , but even then we find two eggs more intimately united and 
independent of the others. From this we may conclude that a female 
always deposits two eggs at once. Dr. Bauer's specimen (v. i.) laid 
also only two eggs. 
Whether larger groups of eggs result from one and the same female, 
that continues depositing eggs on the spot where it already had laid 
two before, or whether such a group contains the eggs of several 
females I do not dare to assert. I observed however that the eggs 
were in different stages of development, but this proves nothing. 
Nevertheless I am inclined to believe that several females choose the 
same spot for their eggs. All the eggs I gathered, were collected on 
one and the same tree and notwithstanding very careful searching on 
different Urostigma — though not U. rumphii — in the neighbourhood 
I could not succeed in finding one single specimen more of these easily 
visible eggs. This makes it probable that the animals choose only this 
tree. The very smooth bark that is peculiar to Urostigma rumphii 
may well explain this fact, for it will indeed prove useful in adhering 
the eggs to it with a broad face. This face of the egg is rather soft ; 
the other part of the eggshell is as hard as porcelain and will break easily. 
The size of the egg compared with the size of the animal is very 
remarkable; but this is also the case with other Geckotidae, whose 
eggs are also very large. 
1) The only notice I know of, is the remark of Dr. F. H. Bauer (Proc. Zool. Soc. 
London 1886 pag. 718) about a living specimen: „It appeared to be a female, for only 
a few days after its capture it laid two eggs in the box in which it was kept".
