Detailed List of Specimens. 143 



occur throughout the islands on this part of the coast. — (Nar- 

 rative, i. p. 401.) 



Montagu Sound, about five-and-twenty miles south-west 

 of Admiralty Gulf, (Narrative, i. p. 400.) — Grayish granu- 

 lar quartz; like that of the Lickey Hill, in Worcestershire. 

 Fine-grained quartzose sand-stone of a purplish hue, resembling 

 a rock on the banks of the Severn, near Bridgenorth. Gray 

 and reddish sand-stone; apparently composed of the debris of 

 granite, and very nearly resembling that of Simms's Island 

 above mentioned. 



Hunter's River, falling into York Sound, on the north- 

 east side. — Somewhat coarse reddish- white sandstone; like 

 that of the coal formation, and some varieties of millstone grit. 

 Fine-grained, reddish-gray quartzose sand-stone, having the 

 appearance of stratification, and resembling the rocks of Cam- 

 bridge Gulf. 



Roe's River, at the eastern termination of York Sound, 

 (Narrative, i. p. 407, 408, 413,) runs between precipitous banks 

 of sand-stone, in nearly horizontal strata, which rise to the 

 height of three hundred feet. 



Careening Bay, between York Sound and Prince Regent's 

 River, (Narrative, vol. i. page 413; and vol. ii. page 43, &c.) 

 — Crystalline epidote, and whitish quartz, apparently from a 

 vein. Purplish-brown epidote, with small nests or concretions 

 of green epidote and quartz ; forming a sort of amygdaloid. 

 Conglomerate, containing angular fragments of yellowish -gray 

 quartz-rock, in a base of compact epidote. A nearly uniform 

 greenish compound of epidote intimately mixed with quartz, 

 also occurs at this place. Flat lamellar calcedony. Very fine- 

 grained reddish-gray quartzose sand-stone, with traces of a 

 slaty structure, resembling that of York Sound, and Cambridge 

 Gulf, was found in the north-east end of this bay; and fine- 

 grained green-stone, on the summit of the adjacent hills. 



Several of these specimens are almost identical with those 

 of Port Warrender ; from which place Careening Bay is distant 

 about sixty miles. 



Bat Island, (Narr. i. p. 432,) western entrance of Careen- 

 ing Bay. — Quartz from thin veins, with particles of an ad- 

 hering rock, probably chlorite-slate. Quartz, containing dis- 

 seminated hematitic iron-ore and copper pyrites. Quartz cry- 

 stals, with calcedony, from nodules in amygdaloid. Quartz 

 with specular iron ore. Green-stone, with calcedony and cop- 

 per pyrites. A decomposed stone, probably consisting of 

 wacke. — The specimens of trap-rocks from this place are from 

 a cavern.
