 by Captain Sir Edward Belcher, C.B., 1852-54, and by Captain 

 Inglefield (1853-54), described by Mr. Salter in the Appendix to 

 " The Last of the Arctic Voyages " by Captain Sir E. Belcher, E.N. 

 (London, 1855, vol. ii. p. 377, pi. xxxvi.). 



Those from Albert Land, etc., are of Carboniferous age, consisting 

 of Corals, Brachiopoda, etc., ClisiophyUum, Zaphrentis, Syringopora, 

 Fenestella, Spirifer, Productus 2 sjd., etc. Those from Cape Eiley 

 and Beechey Island, both sides of Wellington and Queen's Channel, 

 Seal and Cornwallis Islands, are of Silurian age, and some few are 

 perhaps Devonian. 



Writing of Beechey Island, Dr. Sutherland observes : — " Geo- 

 logical specimens were obtained in great abundance. Favosites, 

 Catenipora, CyatliopTiyllum, Porites, and Fucoid impressions were 

 very common forms of organic remains. At Cape Eiley, and also 

 on Beechey Island, Favosites gothlandica was found almost every- 

 where in great abundance, but especially at the latter place, where 

 it occurs in situ.^'

" This fine coral (writes Mr. Salter), which we dedicate with great 

 pleasure to the gallant commander of the Expedition, is one of the 

 most frequent species. It occurs in the form of rounded masses 

 from an inch to several inches in diameter, covered on all sides with 

 stellate cells — at first sight looking very like the Astrece- of the 

 present seas. The internal structure, however, as of nearly all the 

 corals of the older rocks, is quite of another order. . . . Prof. 

 M'Coy prefers to regard this as a Clisiophyllum rather than a 

 Strephodes from the internal structure ; it is, however, so imperfectly 

 shown in the sections I was able to make, and the twisting of the 

 lamella is so conspicuous, that I leave it here for the present." * 



" Surface covered by hexagonal or pentagonal cells, of various 

 sizes, the larger ones frequently four lines across, the smaller ones in 

 groups of two, three or more, at the angles of the others. The 

 extreme edges of the cups are thin and crenulated, their sides 

 thickened and sloping steeply. In a large star they are radiated by 

 about 30 or 40 equal blunt lamellge, which extend to the base, and 

 about half of them are there united in bundles of three or four, and 

 are twisted upon the surface of a low boss which rises from the 

 centre. The lamellse are united everywhere by frequent vesicular 

 plates. A transverse section below the cup shows narrow, but 

 distinct, divisional walls between the cells, and the lamellse twisted i 

 in the middle and united loosely by the vesicular tissue. The 

 intermediate ones in the section appear shorter than they are in the 

 cup. A longitudal section shows the vesicular plates arched a little 

 upwards in the middle under the boss, then downwards, and again 



1 On a reconsideration of these Palseozoic Corals, probably it may be found possible 

 to bring Strephodes and Lonsdalia near, or even to unite them together.
