'388 Dr. H. Woodtoard — On some Arctic Fossils — 



Localities. — Griffith's Island, Cape Eiley and Beecliey Island. 

 Leopold's Island (frequent), 



Yig. 3 was obtained by Dr. Horner of the S.Y. "Pandora" from 

 the shore of Beechey Island, August 25, 1875.

Corallium Gothlandicum, Linn., Calamopora Gothlandica, Goldf. Petref. Germ, 

 t. 26, fig. 3, and C. balthica, fig. 4. 



This is a very common species, having been brought home by Dr. 

 Horner ("Pandora"), and also by Captains Austin of the " Eesolute." 

 and Ommanney of the "Assistance," and by Captain Penny. Mr. 

 Salter finds it to be quite identical with Goldfuss's figure. 



"On the same specimens," he writes,^ "a single or double alter- 

 nating row of pores may be seen on each face and the distance 

 between the transverse partitions (diaphragms) varies much ; in the 

 same tube we have, within a very short distance, 5, 4, 3, 2, and 

 1^ diaphragms in the space of one diameter. The columns also 

 vary much in size." 



Localities — Griffith's, Cornwallis, Leopold and Beechey Islands, 

 very widely distributed.

In MM. Edward's and Haime's Monograph on British Fossil 

 Corals, p. 232, the authors observe : " We are inclined to consider 

 the Strephodes gracilis, of M'Coy, as belonging to the genus Oyatlio- 

 phyllum." We cannot but think that Strephodes Pichthornii should 

 also be referred to that genus. From a large number of specimens 

 examined by us in the Arctic collections already mentioned, it 

 certainly does not affect the mode of aggregate or composite growth 

 attributed to Strephodes ; all the individuals being found growing 

 distinct even when placed closely together in the same rock-mass. 



Mr. Salter describes this species as follows : " The tube is short, 

 conical, and longitudinally striated ; sometimes annulated and rugose 

 in growth : and it grows rapidly in breadth, — in the length of an 

 inch and a half attaining an inch in diameter. The cup is very 

 deep, its sides formed of about 56 narrow lamellee of equal size, 

 connected by cross-bars, which are the edges of vesicular plates. 

 Half of these lamellae stop short at the bottom of the cup, but the 

 rest cross a shallow depression, and are then twisted a little into 

 bundles, and united on the crown of a low boss, which is not nearly 

 elevated enough to constitute it a Glisiophylhmi. At first sight the 

 coral looks like a Petraia,^ but the vesicular plates between the 

 numerous lamellae removes it from this genus." 



Localities. — Cape Eiley and Beechey Island, Griffith's and Corn- 

 wallis Islands. 



Fig. 5 on Plate X. was obtained by G. E. De Wilde, Esq. (of the 

 "Pandora"), at Beechey Island, in 1875, and is now in the British 



1 Appendix to Sutherland's Journal, p. ccxxviii. 



2 Named after Mr. Pickthorne, surgeon of the " Pioneer." 



3 Some of the specimens marked S. Fickthornii may helong to a species of 

 Fetraia ; they are, however, too much weathered to be safely determined.
