the mainland H. (Gcotrochiis) zeno and ff. Broadhenti. The 

 latter extends to Port Moresby. The aspect differs greatly from 

 the West of the Gulf of Papua — at Katow there are bold lofty 

 mountain ranges flanked by hills of various altitudes. In fact 

 there is a total change in the aspect, not only as far as the 

 physical appearance, but the natives also differ, for here we have 

 the yellow skinned Polynesian, at Katow and to the west the 

 natives belong to the Black Papuan race. 



At Port Moresby about 75 miles south-east of Hall Sound, I 

 made a lengthy stay with three companions collecting specimens 

 of Natural History, visiting the coast villages, and collecting in 

 their immediate vicinity and making short journeys into the 

 interior. The full length of the coast of the Peninsula is traversed 

 by a low range of hills, seldom more than 300 feet in altitude, of 

 modern tertiary origin, covered with the debris of corals and 

 shells apparently of species existing on the coral reefs adjacent; 

 they are consequently very dry and bare of vegetation, except 

 coarse grass and straggling dwarf Eucalypti. In the indentations 

 a few more shrubs and trees struggle for an existence, and here 

 and there in the guUeys where a greater quantity of alluvium has 

 accumulated, a denser scrub exists. On this coast-range land shells 

 are almost totally absent, in fact I could only find, after diligent 

 search, a single dead specimen of a small HelLx, apparently the 

 widely diffused Helix rustica of iVustralia. Beyond the coast- 

 range the country is a general undulating plain, covered with high 

 coarse Eucalypti and an occasional patch of tropical verdure 

 around water-holes and on the banks of creeks. These plains are 

 also destitute of Land Molluscs, that is so far as I could observe, 

 although a few fresh-water shells exist, viz: — one small sp. of Unio 

 bearing a great resemblance to a sort I have collected in the 

 Richmond River, New South Wales; one sp. of carinated Physa, 

 one sp. of Melanin, and one AwpJiipeplea closely allied to a 

 Queensland form.
