No. IV. APPENDIX. 387 



No. X. BEIDPOET INLET, Melville Island (Lat. 75° N. ; Long. 



1090 W.). 



Coal, with impressions of Sphenopteris. 



Ferruginous spotted wMte sandstone. 



Clay ironstone, passing into brown hematite. 



No. XI. SKENE BAY, Melville Island (Lat. 75° N. ; Long. 108° W.). 

 Bituminous coal, with finely divided laminse, associated with brown 

 crystalline limestone, with cherty beds, and grey-yellowish sand- 

 stone, passing into brownish-red sandstone. 



No. XII. HOOPEE ISLAND, Liddon's Gulf, Melville Island (Lat. 

 75° 5' N.; Long. 112° W.). 

 Nodules of clay ironstone, very pure and heavy, associated with 

 ferruginous fine sandstone and coal of the usual description. 



The hill-tops and sides along the south shore of 

 Liddon's Gulf, and as far as Cape Dundas, are gene- 

 rally bare, composed of frozen mud, arising from the 

 disintegration of shale, the annual dissolving snows 

 washing them down and giving them a rounded form. 

 The southern slopes generally support vegetation. 

 Fragments of coal are very frequently met with, and 

 at the mouth of a ravine on the south shore of Liddon's 

 Gulf there is abundance, of very good quality ; it con- 

 tains a considerable quantity of pyrites or bisulphuret of 

 iron. 



No. XIII. BYAM MAETINS ISLAND (Lat. 75° 10' N. ; Long. 



1040 15' W.). 

 Yellowish-grey sandstone, in situ, containing a ribbed Airypa, 



allied to the A. primipilaris of V. Buch, and the A . fallax of the 



carboniferous rocks of Ireland. 

 Eeddish limestone, with broken fragments of shells, of the same 



description of brachiopod as the last. 

 Coal of the usual description. 

 Fine-grained red sandstone, passing into red slate. 

 Scoriaceous homblendic trap (boulders). 



The sandstone of Byam Martin's Island is of two 

 kinds — one red, finely stratified, passing into purple 

 slate, and very like the red sandstone of Cape Bunny, 

 North Somerset, and some varieties of the red sandstone 

 and slate found between Wolstenholme Sound and
