possible to classes, on the principle of the " Tinneh." Thus 

 along Paget Sound, &c, I comprise the numerous homish, dmish, 

 and wdmish, all modifications of the same general affix, under 

 one head as the dmish tribes ; and along the west coast of Van- 

 couver's Island, and the adjacent coast southward, the dht tribes, 

 this being the general affix, Nootk-dht, Clayo-qu-dht, &c. North- 

 ward of these the Hdi-dah occupy Queen Charlotte's Islands and 

 the Prince of Wales portion of the Archipelago. On the main- 

 land north of Vancouver's Island and in the Islands of Milbank 

 Sound and connected waters, is the Hailtza connexion ; succeeded 

 northward by the Chimseyan tribes, who occupy as far as 

 Observatory Inlet, near the southern line of Alaska Territory. 

 Thence the Thlinkitt connexion to beyond the Tah-Co River, 

 who are succeeded by the tribe called by the Russians " Kaliu- 

 ches" ; and finally, beyond Cook's Inlet, the Esquimaux. 



NOTES ON A COLLECTION OF GEOLOGICAL 

 SPECIMENS. 



Collected by WlLLIAM Macleay, Esq., F.L.S., President of 

 the New \South Wales Linnean Society, Sydney, from the 

 coast of New Guinea, Cape York, and neighbouring islands, 

 by C. S. Wilkinson, Government Geologist. {Read before 

 the Linnean Society, Sydney, 28th February, 1876.) 



I have lately examined a small collection of geological speci- 

 mens, brought from the coast of New Guinea by the President of 

 of this Society, Mr. William Macleay, and which were collected 

 by him when on his recent tour of exploration in the Chevert. 



These specimens consist of — 



1. Quartz porphyry (Palaeozoic), from Cape York, found under- 

 lying beds of Tertiary ferruginous sandstone. 



2. Vesicular basalt and brecciated volcanic tufa (Upper Ter- 

 tiary), from Daruley Island. 



3. Small concretions of limonite, with polished-looking surfa- 

 ces, dredged up off the coast of New Guinea. 



4. Specimens of chalcedony and flint, from Hall's Sound.
