he collection of Reptiles treated in the following pages is chiefly obtained in 
Northwestern Australia, as well in the interior as at the coast, but a certain 
number of specimens were also secured near Melbourne, and in southern Queensland. 
It contains some new species, as well of lizards as of snakes. The collection of Sea- 
snakes appears to be rather representative for the coast of Western Australia, and 
it contains not only some species unrecorded from these waters before, but even two 
species quite new to science. 
A small Gecko representing a new genus related to Diplodactylus and Oedura 
is of special interest, and in addition to that there are a couple of new Lygosomas, 
resp. to the sections Hinulia and Siaphos, both from the south-eastern part of the 
continent, and a new Ablepharus. The only chelonian contained in the collection 
belongs to a wellknown species but is nevertheless of interest in consequence of its 
Juvenile stage which exhibits several aberrant characteristics. 
The collection belongs now to the BR. Nat. Hist. Museum in Stockholm.
