inclined upwards in the outer area in two or three rows of cells. In 

 these sections both the lamellas and the transverse plates are thin, 

 and the former are wavy."

Our specimen, PL X. Fig. 1, is from Beechey Island, and was 

 collected and brought home by Dr. A. Horner, of the S.Y. " Pandora " 

 (Capt. Sir Allen Toung, E.N.). It is clearly a young example, the 

 corallites not having increased by calycial gemmation many times, so 

 as to form such a fine, evenly-rounded composite mass as that repre- 

 sented in Fig. 2. 



With reference to the fine rounded composite Coral, Plate X. Fig. 

 2, I was greatly perplexed for some time, and was almost inclined 

 to refer it to the genus Acervularia ; but after a more careful exami- 

 nation, and by comparing it with numerous other specimens, I have 

 been led to the conclusion that it is merely a StrepJiodes Austini, in 

 which the extremely sharp crenulated edges dividing the calices 

 from one another, which in young and unworn specimens (as in 

 Fig. 1) stand boldly up in hexagonal or pentagonal lines, have been 

 removed by weathering over the whole upper surface, exposing 

 thereby the lower wall of the calices where they are thickened by 

 the septal radii and strengthened by numerous interseptal dissepi- 

 ments. The sides of the calices are in some instances worn down to 

 a level with the columella, giving the Coral the appearance of a well- 

 (acic?-) developed Acervularia luxurians from Dudley; but this is 

 deceptive, for on examining the margins of the specimen, the divid- 

 ing ridges between the calices are seen nearly as well preserved as in 

 Fig. 1, changing entirely the character of the specimen. Several 

 similar rounded masses are in Sutherland's Collection from Beechey 

 Island, etc. This specimen is interesting as having been brought 

 from Port Dundas, which, like Cape Eiley, is on the South Coast of 

 N. Devon, but 200 miles to the Eastward, on the N. shore of Lancas- 

 ter Sound, Lat. 75° N. It was presented to the British Museum by 

 Thomas Crowther Brown, Esq. Probably brought home by one of 

 the crew of the "Phoenix" (Capt. Inglefield), 1853-54.

Mr. Salter writes : " Well-preserved specimens are frequent ; and 

 both the polymorphous (fig. 9) and branched varieties are found at 

 Grifath's Island. 



" The tubes are by no means of equal size, — numerous small ones 

 occurring between the others. The edges are somewhat thickened. 

 Internally the tubes are sometimes cylindrical and smooth, at others 

 more prismatic. They are sometimes faintly striated inside. The 

 pores occur in single rows at wide distances apart. The transverse 

 diaphragms are not visible in these specimens." Mr. Salter alludes 

 also to another specimen which agrees well with the F. crassa of 

 M'Coy.
