THE STRAIT OF MAGELLAN. 449 



of the men this day brought me a beautiful white Doris 

 which he had found on the kelp, and a fish taken had a 

 species of Lernceocera attached to one of its eyes. 



The 20th was fair during the greater part of the day, but 

 heavy rain came on in the evening. We remained at anchor, 

 as it was Sunday, and next morning got under way, and 

 moved southwards through Smyth's Channel, looking for 

 harbours as we went along. We reached ShoU Bay on a fine 

 bright evening, which remarkably contrasted with our former 

 experiences in the same locality, gaining, shortly before we 

 anchored, a magnificent view of various rugged gray moun- 

 tains and snowy peaks, as well as of a glacier several miles in 

 extent, fed by a dazzKng snow-field at its head. 



On the morning of the 22d the dredge yielded a specimen 

 of the long-spined Echinocidaris^ procured on the previous 

 season, together with some Crustacea of the genus Eurypodius, 

 and several dead shells of Molluscs, including valves of 

 Terebratulae, and of a small species of Cardita, the G. Thouarsii, 

 described by D'Orbigny, from the Falkland Islands.* The day 

 being bright and clear, we got under way after breakfast, and 

 crossed the Strait of Magellan to the opposite Fuegian coast. 

 As we approached it the appearance presented by its wall of 

 precipitous gray mountains of the most wild and fantastic 

 forms, rising sheer out of the water, was very remarkable in 

 its excessive dreariness, well meriting Narborough's name of 

 Island of Desolation. We first entered Tuesday Bay, which 

 we found to be a very fine harbour, with a comparatively 

 narrow entrance, and inside a large extent of water available 

 for anchorage, and after taking some soundings there, made 

 our exit, moving westwards to Port Mercy, a very unsafe 

 anchorage, lying quite open to westerly gales. After scruti- 



* A species of Peronia was also here obtained. It is figured at p. 75.
