Umhellularia Grcmlandica was discovered by " Captain Adrians 

 (of the English Greenland ship the ' Britannia ')j a native of Jut- 

 land." Two specimens " were drawn up with the line, as they 

 were sounding the sea, out of a clayish ground, 236 fathoms 

 deep, that is, 1416 feet, in 79 degrees North latitude, about 

 90 English miles from Greenland." "Each of the two plants 

 was broke into three pieces, which accident, however, did not 

 hinder me from laying it before me according to its compleat 

 form and size." 



The captain gave them to ]M. Dunze of Bremen ; and the 

 latter gave one to ^I. Christlob !Mylius, who described and 

 figured it in a pamphlet entitled ' An Account of a new Zoo- 

 phyte,' 8vo, 1754, and the other to Mr. Collinson, who trans- 

 ferred it to John Ellis, by whom it was described and figured in 

 his work on Corallines. The specimen that belonged to Mylius 

 was given by him to M. Ilollmann of Gottingen, according to 

 Pallas's * Zoophytes,' p. 366. "What has become of Ellis's spe- 

 cimen is not known; it has probably been destroyed; and the 

 specimen that was in M. Ilollmann's collection in 1766 has not 

 since been refeiTcd to. 



No other specimens appear to have been discovered, which is 

 very remarkable when we consider the number of shij)s which 

 visit the Northern seas, and the attention which the Danish, 

 Norwegian, and Swedish naturalists (especially the former) 

 have paid to the natural productions of the coast of Green- 

 land. 



All the accounts of the coral in the more modern zoological 

 works have been taken from Ellis's description and figure; 

 there are some details in the previous account of Mylius which 

 have been overlooked; he also gave a history of the discovery 

 and the means by which the coral came into his hands, which 

 is entirely omitted by Ellis.
